Community-Oriented Policing and Problem-Oriented Policing

In 1979, Hermon Goldstein observed from several studies conducted at the time on standard policing practices that law enforcement agencies seemed to be more concerned about the means rather than the goals of policing. He argued that law enforcement agencies should shift away from the traditional, standard model of policing and that police become more proactive, rather than reactive, in their approaches to crime and disorder (Hinkle et al., 2020; Weisburd et al., 2010). Goldstein’s work set the stage for the development of two new models of policing: community-oriented policing (COP) and problem-oriented policing (POP).

COP is a broad policing strategy that relies heavily on community involvement and partnerships, and on police presence in the community, to address local crime and disorder. POP provides law enforcement agencies with an analytic method to develop strategies to prevent and reduce crime and disorder, which involves problem identification, analysis, response, and assessment (National Research Council, 2018).

Although COP and POP differ in many ways, including the intensity of focus and diversity of approaches (National Research Council, 2004), there are several important similarities between them. For example, COP and POP both represent forms of proactive policing, meaning they focus on preventing crime before it happens rather than just reacting to it after it happens. Further, both COP and POP require cooperation among multiple agencies and partners, including community members (National Research Council, 2018). In addition, POP and COP overlap in that each involves the community in defining the problems and identifying interventions (Greene, 2000).

Although few studies focus on youth involvement in COP and POP, youths can play an important role in both strategies. In COP, youths often are part of the community with whom police work to identify and address problems. Youths can be formally involved in the process (i.e., engaging in local community meetings) or informally involved in efforts to strengthen the relationship between the police and members of the community. For example, a police officer on foot patrol may decide to engage with youths in the community through casual conversation, as part of a COP approach (Cowell and Kringen, 2016). Or police might encourage youth to participate in activities, such as police athletic leagues, which were designed to prevent and reduce the occurrence of juvenile crime and delinquency, while also seeking to improve police and youth attitudes toward each other (Rabois and Haaga, 2002). Using POP, law enforcement agencies may specifically focus on juvenile-related problems of crime and disorder. For example, the Operation Ceasefire intervention, implemented in Boston, MA, is a POP strategy that concentrated on reducing homicide victimization among young people in the city (Braga and Pierce, 2005).

This literature review discusses COP and POP in two separate sections. In each section, definitions of the approaches are provided, along with discussions on theory, examples of specific types of programs, overlaps with other policing strategies, and outcome evidence.

Specific research on how police and youth interact with each other in the community will not be discussed in this review but can be found in the Interactions Between Youth and Law Enforcement literature review on the Model Programs Guide.  

Community-Oriented Policing Definition

Community-oriented policing (COP), also called community policing, is defined by the federal Office of Community-Oriented Policing Services as “a philosophy that promotes organizational strategies that support the systemic use of partnerships and problem-solving techniques to proactively address the immediate conditions that give rise to public safety issues such as crime, social disorder, and fear of crime” (Office of Community-Oriented Policing Services, 2012:3). This policing strategy focuses on developing relationships with members of the community to address community problems, by building social resilience and collective efficacy, and by strengthening infrastructure for crime prevention. COP also emphasizes preventive, proactive policing; the approach calls for police to concentrate on solving the problems of crime and disorder in neighborhoods rather than simply responding to calls for service. This model considerably expands the scope of policing activities, because the targets of interest are not only crimes but also sources of physical and social disorder (Weisburd et al., 2008).

After gaining acceptance as an alternative to traditional policing models in the 1980s, COP has received greater attention and been used more frequently throughout the 21st century (Greene, 2000; National Research Council, 2018; Paez and Dierenfeldt, 2020). The Violent Crime Control and Law Enforcement Act of 1994 articulated the goal of putting 100,000 additional community police officers on the streets and established the federal Office of Community-Oriented Policing Services. Research from 2013 suggests that 9 out of 10 law enforcement agencies in the United States that serve a population of 25,000 or more had adopted some type of community policing strategy (Reaves, 2015).

COP comprises three key components (Office of Community-Oriented Policing Services, 2012):

• Community Partnerships. COP encourages partnerships with stakeholders in the community, including other government agencies (prosecutors, health and human services, child support services and schools); community members/groups (volunteers, activists, residents, and other individuals who have an interest in the community); nonprofits/service providers (advocacy groups, victim groups, and community development corporations); and private businesses. The media also are an important mechanism that police use to communicate with the community.
• Organizational Transformation. COP emphasizes the alignment of management, structure, personnel, and information systems within police departments to support the philosophy. These changes may include increased transparency, leadership that reinforces COP values, strategic geographic deployment, training, and access to data.
• Problem-Solving. Proactive, systematic, routine problem-solving is the final key component of COP. COP encourages police to develop solutions to underlying conditions that contribute to public safety problems, rather than responding to crime only after it occurs. The SARA model (which stands for Scanning, Analysis, Response, and Assessment) is one major conceptual model of problem-solving that can be used by officers (for a full description of the SARA model, see Problem-Oriented Policing below).

At the heart of COP is a redefinition of the relationship between the police and the community, so that the two collaborate to identify and solve community problems. Through this relationship, the community becomes a “co-producer” of public safety in that the problem-solving process draws on citizen expertise in identifying and understanding social issues that create crime, disorder, and fear in the community (Skolnick and Bayley, 1988; Gill et al., 2014; National Research Council, 2018).

COP is not a single coherent program; rather, it encompasses a variety of programs or strategies that rest on the assumption that policing must involve the community. Elements typically associated with COP programs include the empowerment of the community; a belief in a broad police function; the reliance of police on citizens for authority, information, and collaboration; specific tactics (or tactics that are targeted at particular problems, such as focused deterrence strategies) rather than general tactics (or tactics that are targeted at the general population, such as preventive patrol); and decentralized authority to respond to local needs (Zhao, He, and Lovrich, 2003). One Major Cities Chiefs Association (MCCA) survey of MCCA members found that some of the most common COP activities were officer representation at community meetings, bicycle patrols, citizen volunteers, foot patrols, police “mini-stations” (see description below), and neighborhood storefront offices (Scrivner and Stephens, 2015; National Research Council, 2018).

Community members who engage in COP programs generally report positive experiences. For example, residents who received home visits by police officers as part of a COP intervention reported high confidence in police and warmth toward officers, compared with residents who did not receive visits (Peyton et al., 2019). Notably, however, those who participate in COP–related activities, such as community meetings, may not be representative of the whole community (Somerville, 2008). Many individuals in communities remain unaware of COP activities, and those who are aware may choose not to participate (Adams, Rohe, and Arcury, 2005; Eve et al., 2003). Additionally, it can be difficult to sustain community participation. While police officers are paid for their participation, community members are not, and involvement could take time away from family and work (Coquilhat, 2008).

Specific Types of COP Programs

Because COP is such a broad approach, programs that involve the community may take on many different forms. For example, some COP programs may take place in a single setting such as a community center, a school, or a police mini-station. Other COP–based programs, such as police foot patrol programs, can encompass the entire neighborhood. The following are different examples of specific types of COP programs and how they can affect youth in a community.

School Resource Officers (SROs) are an example of a commonly implemented COP program in schools. SROs are trained police officers who are uniformed, carry firearms and a police department badge, and have arrest powers. They are tasked with maintaining a presence at schools to promote safety and security (Stern and Petrosino, 2018). The use of SROs is not new; SRO programs first appeared in the 1950s but increased significantly in the 1990s as a response to high-profile incidents of extreme school violence and the subsequent policy reforms (Broll and Howells, 2019; Lindberg, 2015). SROs can fulfill a variety of roles. They are intended to prevent and respond to school-based crime; promote positive relationships among law enforcement, educators, and youth; and foster a positive school climate (Thomas et al., 2013).

The National Association of School Resource Officers (NASRO), the largest professional organization of SROs, formally defines the SRO roles using a “triad model,” which aligns with community policing models (May et al., 2004), and includes the three primary functions of SROs: 1) enforcing the law; 2) educating students, school staff, and the community; and 3) acting as an informal counselor or mentor (Broll and Howells, 2019; Fisher and Hennessy, 2016; Javdani, 2019; Thomas et al., 2013). There may be significant variability in how these roles and responsibilities are balanced, as they are usually defined through a memorandum of understanding between the local law enforcement agency and the school district (Fisher and Hennessy, 2016). Even with the SRO responsibilities formally spelled out, there may still be tensions and ambiguities inherent to the SRO position based on their positioning at the intersection of the education system and the juvenile justice system, which often have competing cultures and authority structures (Fisher and Hennessy, 2016). As members of the police force, the SROs may view problematic behaviors as crimes, whereas educators view them as obstacles to learning. Another ambiguity is that as an informal counselor/mentor, the SRO is expected to assist students with behavioral and legal issues, which may result in a conflict of interest if the adolescent shares information about engaging in illegal activities (Fisher and Hennessy, 2016).

Evaluation findings with regard to the effectiveness of the presence of SROs in schools have been inconsistent. In terms of school-related violence and other behaviors, some studies have found that SROs in schools are related to decreases in serious violence (Sorensen, Shen, and Bushway, 2021; Zhang, 2019), and decreases in incidents of disorder (Zhang, 2019). Others have found increases in drug-related crimes (Gottfredson et al., 2020; Zhang, 2019) associated with the presence of SROs in schools, and other studies have shown no effects on bullying (Broll and Lafferty, 2018; Devlin, Santos, and Gottfredson, 2018). In terms of school discipline, one meta-analysis (Fisher and Hennessy, 2016) examined the relationship between the presence of SROs and exclusionary discipline in U.S. high schools. Analysis of the seven eligible pretest–posttest design studies showed that the presence of SROs was associated with rates of school-based disciplinary incidents that were 21 percent higher than incident rates before implementing an SRO program. However, in another study, of elementary schools, there was no association found between SRO presence and school-related disciplinary outcomes, which ranged from minor consequences, such as a warning or timeout, to more serious consequences such as suspension from school (Curran et al., 2021).

Further, several studies have been conducted on the effects of SROs on students’ attitudes and feelings. One example is a survey of middle and high school students (Theriot and Orme, 2016), which found that experiencing more SRO interactions increased students’ positive attitudes about SROs but decreased school connectedness and was unrelated to feelings of safety. Conversely, findings from a student survey, on the relationship between awareness and perceptions of SROs on school safety and disciplinary experiences, indicated that students’ awareness of the presence of SROs and their perceptions of SROs were associated with increased feelings of safety and a small decrease in disciplinary actions. However, students belonging to racial and ethnic minority groups reported smaller benefits related to SROs, compared with white students (Pentek and Eisenberg, 2018).

Foot Patrol is another example of a program that uses COP elements. Foot patrol involves police officers making neighborhood rounds on foot. It is a policing tactic that involves movement in a set area for the purpose of observation and security (Ratcliffe et al., 2011). The primary goals of foot patrol are to increase the visibility of police officers in a community and to make greater contact and increase rapport with residents. Officers sometimes visit businesses on their beat, respond to calls for service within their assigned areas, and develop an intimate knowledge of the neighborhood. Additionally, police officers on foot patrols may offer a level of “citizen reassurance” to community members and may decrease a resident’s fear of crime by bringing a feeling of safety to the neighborhood (Wakefield, 2006; Ratcliffe et al., 2011; Walker and Katz, 2017). Another duty of foot patrol officers is to engage youth in the community, and some are instructed to go out of their way to engage vulnerable youth. For example, if an officer sees a group of youths hanging out on a street corner, the officer may stop and initiate casual conversation in an effort to build a relationship (Cowell and Kringen, 2016).

Though foot patrols limit the speed at which an officer can respond to a call (compared with patrol in a vehicle), research has found that community members are more comfortable with police being in the neighborhood on foot. Residents are more likely to consider an officer as “being there for the neighborhood” if they are seen on foot (Cordner, 2010; Piza and O’Hara, 2012).

While there are mixed findings regarding the effectiveness of foot patrols on crime (Piza and O’Hara, 2012), improved community relationships are one of the strongest benefits. Research has shown that foot patrol improves the relationships between community members and police officers through increasing approachability, familiarity, and trust Ratcliffe et al. 2011; Kringen, Sedelmaier, and Dlugolenski, 2018). Foot patrols can also have a positive effect on officers. Research demonstrates that officers who participate in foot patrol strategies have higher job satisfaction and a higher sense of achievement (Wakefield, 2006; Walker and Katz, 2017).

Mini-Stations are community-forward stations that allow police to be more accessible to members of a community. Mini-stations (also known as substations, community storefronts, and other names) can be based in many places—such as local businesses, restaurants, or community centers—and can be staffed by police officers, civilian employees, volunteers, or a combination of these groups, and have fewer officers stationed in them (Maguire et al., 2003). These stations allow officers to build on existing relationships with businesses in the area and give citizens easier access to file reports and share community concerns. Additionally, they are a means to achieving greater spatial differentiation, or a way for a police agency to cover a wider area, without the cost of adding a new district station (Maguire et al., 2003). Residents can also go to mini-stations to receive information and handouts about new policing initiatives and programs in the community. Police mini-stations also increase the overall amount of time officers spend in their assigned patrol areas. The concept of mini-stations stems from Japanese kobans , which gained prominence in the late 1980s. Officers who worked in kobans became intimately familiar with the neighborhood they served and were highly accessible to citizens (usually within a 10-minute walk of residential homes) [Young, 2022].

Mini-stations can also be helpful to youth in the community. For example, Youth Safe Haven mini-stations are mini-stations that are deployed in 10 cities by the Eisenhower Foundation. These mini-stations were first developed in the 1980s and are located in numerous youth-related areas, including community centers and schools (Eisenhower Foundation, 2011). In addition to crime outcomes (such as reduced crime and fear of crime), goals of youth-oriented mini-stations include homework help, recreational activities, and providing snacks and social skills training. Older youths can be trained to be volunteers to assist younger youths with mentoring and advocacy. There are mixed findings regarding mini-stations and their effect on crime rates, but research has shown that adults and older youths who participate in mini-station community programs (or have children who participate) are more likely to report crime, and younger youths are more comfortable speaking with police (Eisenhower Foundation, 1999; Eisenhower Foundation, 2011).

Theoretical Foundation

COP approaches are usually rooted in two different theories of crime: broken windows theory and social disorganization theory (Reisig, 2010; National Research Council, 2018). Both focus on community conditions to explain the occurrence of crime and disorder.

Broken Windows Theory asserts that minor forms of physical and social disorder, if left unattended, may lead to more serious crime and urban decay (Wilson and Kelling, 1982). Visual signs of disorder (such as broken windows in abandoned buildings, graffiti, and garbage on the street) may cause fear and withdrawal among community members. This in turn communicates the lack of or substantial decrease in social control in the community, and thus can invite increased levels of disorder and crime (Hinkle and Weisburd, 2008). In response, to protect the community and establish control, the police engage in order maintenance (managing minor offenses and disorders). Four elements of the broken windows strategy explain how interventions based on this approach may lead to crime reduction (Kelling and Coles, 1996). First, dealing with disorder puts police in contact with those who commit more serious crimes. Second, the high visibility of police causes a deterrent effect for potential perpetrators of crime. Third, citizens assert control over neighborhoods, thereby preventing crime. And finally, as problems of disorder and crime become the responsibility of both the community and the police, crime is addressed in an integrated fashion. COP programs rooted in broken windows theory often use residents and local business owners to help identify disorder problems and engage in the development and implementation of a response (Braga, Welsh, and Schnell, 2015).

Social Disorganization Theory focuses on the relationship between crime and neighborhood structure; that is, how places can create conditions that are favorable or unfavorable to crime and delinquency (Kubrin and Weitzer, 2003). Social disorganization refers to the inability of a community to realize common goals and solve chronic problems. According to the social disorganization theory, community factors such as poverty, residential mobility, lack of shared values, and weak social networks decrease a neighborhood’s capacity to control people’s behavior in public, which increases the likelihood of crime (Kornhauser, 1978; Shaw and McKay, 1969 [1942]). Researchers have used various forms of the social disorganization theory to conceptualize community policing, including the systemic model and collective efficacy (Reisig, 2010). The systemic model focuses on how relational and social networks can exert social controls to mediate the adverse effects of structural constraints, such as concentrated poverty and residential instability. The model identifies three social order controls with decreasing levels of influence: 1) private, which includes close friends and family; 2) parochial , which includes neighbors and civic organizations; and 3) public, which includes police (Bursik and Grasmick, 1993; Hunter, 1985). Community policing efforts based on the systemic model can increase informal social controls by working with residents to develop stronger regulatory mechanisms at the parochial and public levels (Kubrin and Weitzer, 2003; Resig, 2010). Collective efficacy, which refers to social cohesion and informal social controls, can mitigate social disorganization. Community policing can promote collective efficacy by employing strategies that enhance police legitimacy in the community and promote procedurally just partnerships, to encourage residents to take responsibility for public spaces and activate local social controls (Resig, 2010).

Outcome Evidence

Although there are numerous programs that incorporate COP, there are limited examples of COP programs that directly target youth, and fewer that have been rigorously evaluated (Forman, 2004; Paez and Dierenfeldt, 2020). The following programs, which are featured on CrimeSolutions , are examples of how COP has been implemented and evaluated in different cities.

The Chicago Alternative Policing Strategy (CAPS , developed in 1993, incorporates aspects of both community and problem-oriented policing (see Problem-Oriented Policing, below). The CAPS approach has been implemented by dividing patrol officers into beat teams and rapid response teams in each of the districts. Beat teams spend most of their time working their beats with community organizations, while rapid response teams concentrate their efforts on excess or low-priority 911 calls. Meetings occur monthly for both teams, and they receive extensive training. This structure enables officers to respond quickly and effectively to problems that they have not been traditionally trained to handle but have learned how to do by receiving training, along with residents, in problem-solving techniques. Civic education, media ads, billboards, brochures, and rallies have been used to promote awareness of the program in the community (Skogan, 1996; Kim and Skogan, 2003).

To evaluate the effects of the CAPS program, one study (Kim and Skogan, 2003) examined the impact on crime rates and 911 calls. Data were collected from January 1996 to June 2002, using a time-series analysis. The study authors found statistically significant reductions in crime rates and 911 calls in police beats that implemented the CAPS program, compared with police beats that did not implement the program.

Some studies have found that foot-patrol interventions make varying impacts on different types of street violence. Operation Impact , a saturation foot-patrol initiative in the Fourth Precinct of Newark, NJ, was selected as the target area based on an in-depth analysis of the spatial distribution of street violence. The initiative primarily involved a nightly patrol of 12 officers in a square-quarter-mile area of the city, which represented an increase in police presence in the target area. Officers also engaged in proactive enforcement actions that were expected to disrupt street-level disorder and narcotics activity in violence-prone areas. One study (Piza and O’Hara, 2012) found that the target area that implemented Operation Impact experienced statistically significant reductions in overall violence, aggravated assaults, and shootings, compared with the control area that implemented standard policing responses. However, there were no statistically significant differences between the target and control areas in incidents of murder or robbery.

With regard to community-based outcomes, other studies have shown that COP programs have demonstrated positive results. A COP intervention implemented in New Haven, CT , consisted of a single unannounced community home visit conducted by uniformed patrol officers from the New Haven Police Department. During the visits, the patrol officers articulated their commitment to building a cooperative relationship with residents and the importance of police and residents working together to keep the community safe. One evaluation found that residents in intervention households who received the COP intervention reported more positive overall attitudes toward police, a greater willingness to cooperate with police, had more positive perceptions of police performance and legitimacy, had higher confidence in police, reported higher scores on perceived warmth toward police, and reported fewer negative beliefs about police, compared with residents who did not receive home visits. These were all statistically significant findings. However, there was no statistically significant difference in willingness to comply with the police between residents in households that received home visits, compared with those who did not (Peyton et al., 2019).

Problem-Oriented Policing Definition

Problem-oriented policing (POP) is a framework that provides law enforcement agencies with an iterative approach to identify, analyze, and respond to the underlying circumstances that lead to crime and disorder in the community and then evaluate and adjust the response as needed (Braga et al., 2001; Hinkle et al., 2020; National Research Council, 2004). The POP approach requires police to focus their attention on problems rather than incidents (Cordner and Biebel, 2005). Problems, in this model, are defined “as chronic conditions or clusters of events that have become the responsibility of the police, either because they have been reported to them, or they have been discovered by proactive police investigation, or because the problems have been found in an investigation of police records” (National Research Council, 2004:92).

The POP strategy contrasts with incident-driven crime prevention approaches, in which police focus on individual occurrences of crime. Instead, POP provides police with an adaptable method to examine the complicated factors that contribute and lead to crime and disorder, and develop customized interventions to address those factors (National Research Council, 2018).

As noted previously, the idea behind the POP approach emanated several decades ago (Goldstein, 1979) from observations that law enforcement agencies seemed to be more concerned about the means rather than the goals of policing, or “means-over-ends syndrome” (Goldstein, 1979; Eck, 2006; MacDonald, 2002). In 1990, this work was expanded to systematically define and describe what it meant to use POP approaches in policing. During the 1990s, law enforcement agencies in the United States and other countries (such as Australia, Canada, and the United Kingdom) began to implement POP strategies (Scott, 2000).

The traditional conceptual model of problem-solving in POP, known as the SARA model, consists of the following four steps (Weisburd et al., 2010; Hinkle et al., 2020; National Research Council, 2004):

• Scanning. Police identify problems that may be leading to incidents of crime and disorder. They may prioritize these problems based on various factors, such as the size of the problem or input from the community.
• Analysis. Police study information about the identified problem or problems, using a variety of data sources, such as crime databases or surveys of community members. They examine information on who is committing crimes, victims, and crime locations, among other factors. Police then use the information on responses to incidents — together with information obtained from other sources — to get a clearer picture of the problem (or problems).
• Response. Police develop and implement tailored strategies to address the identified problems by thinking “outside the box” of traditional police enforcement tactics and creating partnerships with other agencies, community organizations, or members of the community, depending on the problem. Examples of responses in POP interventions include target hardening, area cleanup, increased patrol, crime prevention through environmental design measures, multiagency cooperation, and nuisance abatement.
• Assessment. Police evaluate the impact of the response through self-assessments and other methods (such as process or outcome evaluations) to determine how well the response has been carried out and what has been accomplished (or not accomplished). This step may also involve adjustment of the response, depending on the results of the assessment.

The SARA model was first defined by a POP project conducted in Newport News, VA, during the 1980s. The Newport News Task Force designed a four-stage problem-solving process . A case study of the project revealed that officers and their supervisors identified problems, analyzed, and responded to these problems through this process, thus leading to the SARA model (Eck and Spelman, 1987).

Since the creation and development of SARA, other models have been established, in part to overcome some noted weaknesses of the original model, such as an oversimplification of complex processes or a process in which problem-solving is nonlinear. These other models include the following 1) PROCTOR (which stands for PROblem, Cause, Tactic or Treatment, Output, and Result); 2) the 5I’s (Intelligence, Intervention, Implementation, Involvement, and Impact); and 3) the ID PARTNERS (which stands for I dentify the demand; D rivers; P roblem; A im, R esearch and analysis; T hink creatively; N egotiate and initiate responses; E valuate; R eview; and S uccess) [Sidebottom and Tilley, 2010]. However, compared with these models, the SARA model appears to be used more often by agencies that apply a POP approach to law enforcement (Sidebottom and Tilley, 2010; Borrion et al., 2020).

A POP approach can be used by law enforcement agencies to address youth-related issues, including offenses committed by youths (such as gun violence, vandalism, graffiti, and other youth-specific behaviors such as running away from home or underage drinking.

For example, in the 2019–20 school year, about one third of public schools experienced vandalism (Wang et al., 2022). If a police agency wanted to tackle the problem of school vandalism , often committed by youth, they could apply the SARA model to determine the scope of the problem, develop an appropriate response, and conduct an overall assessment of efforts. A problem-oriented guide, put together by the Problem-Oriented Policing Center at Arizona State University, outlines the steps that law enforcement agencies can take to use the SARA model and address the issues of vandalism committed specifically at schools (Johnson, 2005).

Thus, during the scanning step of the SARA model, to identify the problem police would focus on the specific problem of school vandalism by examining multiple sources of data, including information gathered from both police departments and school districts. During the analysis step, police would ask about the specific school vandalism problems they are targeting, such as 1) how many and which schools reported vandalism to the police, 2) which schools were vandalized, 3) what are the characteristics (such as the age, gender, school attendance rate) of any youth identified as committing the vandalism, and 4) on what days and times the vandalism occurred. The analysis step also should include information from various data sources, including official reports to the police of school vandalism incidents, interviews with SROs, and information from students at the school (Johnson, 2005).

Once police have analyzed the school vandalism problem and have a clear picture of the issue, they would then move on to the response step. The response depends on what police learn about the vandalism problem at schools. For example, if police find that vandalism occurs because youths have easy access to school grounds, especially after school hours, they might suggest a response that improves building security. Finally, during the assessment stage, police would determine the degree of effectiveness of their response to school vandalism through various measures of success, such as the reduction in the number of incidents of vandalism, the decrease in the costs for repair of damaged property, and the increase of incidents (when they do occur) in which the person or persons who engaged in vandalism are identified and apprehended (Johnson, 2005).

Overlap of POP With Other Policing Strategies

POP shares several similarities and overlapping features with other policing models, such as focused deterrence strategies and hot-spots policing. Hot-spots policing involves focusing police resources on crime “hot spots,” which are specific areas in the community where crime tends to cluster. Hot-spots policing interventions tend to rely mostly on traditional law enforcement approaches (National Research Council, 2004; Braga et al., 2019). Focused deterrence strategies (also referred to as “pulling levers” policing) follow the core principles of deterrence theory. These strategies target specific criminal behavior committed by a small number of individuals who repeatedly offend and who are vulnerable to sanctions and punishment (Braga, Weisburd, and Turchan, 2018).

While POP, focused deterrence, and hot spots policing are three distinct policing strategies, there can be an overlap in techniques. For example, a POP approach can involve the identification and targeting of crime hot spots, if the scanning and analysis of the crime problems in a community reveal that crime is clustering in specific areas. Further, a hot-spots policing intervention may use a problem-oriented approach to determine appropriate responses to address the crime in identified hot spots. However, POP can go beyond examination of place-based crime problems, and hot-spots policing does not require the detailed analytic approach used in POP to discern which strategy is appropriate to prevent or reduce crime (Hinkle et al., 2020; National Research Council, 2018; Gill et al., 2018). Similarly, POP involves targeting resources to specific, identified problems, in a similar way that focused deterrence strategies target specific crimes committed by known high-risk offenders. However, focused deterrence strategies tend to rely primarily on police officers to implement programs, whereas POP may involve a variety of agencies and community members (National Research Council, 2004).

Although POP, focused deterrence, and hot-spots policing differ in some distinct ways (such as intensity of focus and involvement of other agencies), these strategies may often overlap (National Research Council, 2004).

POP draws on theories of criminal opportunity to explain why crime occurs and to identify ways of addressing crime, often by altering environmental conditions (Reisig, 2010). While much criminological research and theory are concerned with why some individuals offend in general, POP strategies often concentrate on why individuals commit crimes at particular places, at particular times, and against certain targets (Braga, 2008; Goldstein, 1979; Eck and Spelman, 1987; Eck and Madensen, 2012). Thus, POP draws on several theoretical perspectives that focus on how likely individuals (including those who may commit a crime and those who may be victimized) make decisions based on perceived opportunities. These include rational choice theory, routine activities theory , and situational crime prevention (Braga, 2008; Braga et al., 1999; Eck and Madensen, 2012; Hinkle et al., 2020; McGarrell, Freilich, and Chermak, 2007). These three theories are considered complements to one another (Tillyer and Eck, 2011).

Rational Choice Theory focuses on how incentives and constraints affect behavior (Cornish and Clark 1986; Gull, 2009). In criminology, rational choice theory draws on the concepts of free will and rational thinking to examine an individual’s specific decision-making processes and choices of crime settings by emphasizing their motives in different situations. The starting point for rational choice theory is that crime is chosen for its benefits. Thus, rational choice theory informs POP by helping to examine and eliminate opportunities for crime within certain settings. Eliminating these opportunities should help to intervene with a potential offender’s motives to commit a crime (Karğın, 2010).

Routine Activity Theory , formulated by Cohen and Felson (1979), is the study of crime as an event, highlighting its relation to space and time and emphasizing its ecological nature (Mir ó–Llinares , 2014). It was originally developed to explain macro-level crime trends through the interaction of targets, offenders, and guardians (Eck, 2003). The theory explains that problems are created when offenders and targets repeatedly come together, and guardians fail to act. Since its formulation, routine activity theory has expanded. In terms of POP, routine activity theory implies that crime can be prevented if the chances of the three elements of crime (suitable target, motivated offender, and accessible place) intersecting at the same place and at the same time are minimized (Karğın, 2010). The SARA problem-solving methodology allows law enforcement agencies to examine and identify the features of places and potential targets that might generate crime opportunities for a motivated offender and develop solutions to eliminate these opportunities, thereby preventing future crime (Hinkle et al., 2020).

Situational Crime Prevention was designed to address specific forms of crime by systematically manipulating or managing the immediate environment with the purpose of reducing opportunities for crime. The goal is to change an individual’s decisionmaking processes by altering the perceived costs and benefits of crime by identifying specific settings (Clarke, 1995; Tillyer and Eck, 2011). Situational crime prevention has identified a number of ways to reduce opportunity to commit crime, such as: 1) increase the effort required to carry out the crime, 2) increase the risks faced in completing the crime, 3) reduce the rewards or benefits expected from the crime, 4) remove excuses to rationalize or justify engaging in criminal action, and 5) avoid provocations that may tempt or incite individuals into criminal acts (Clarke 2009). Certain POP strategies make use of situation crime prevention tactics during the response phase, such as physical improvements to identified problem locations. These may include fixing or installing street lighting, securing vacant lots, and getting rid of trash from the streets (Braga et al., 1999).

Although the POP approach is a well-known and popular approach in law enforcement, there have been a limited number of rigorous program evaluations, such as randomized controlled trials (National Research Council 2018; Gill et al. 2018), and even fewer evaluations specifically centered on youth. 

One meta-analysis (Weisburd et al., 2008) reviewed 10 studies, which examined the effects of problem-oriented policing on crime and disorder. These included various POP interventions and took place in eight cities across the United States (Atlanta, GA; Jersey City, NJ; Knoxville, TN; Oakland, CA; Minneapolis, MN; Philadelphia, PA; San Diego, CA; and one suburban Pennsylvania area.) and six wards in the United Kingdom. The studies evaluated interventions focused on reducing recidivism for individuals on probation or parole; interventions on specific place-based problems (such as drug markets, vandalism and drinking in a park, and crime in hot spots of violence); and interventions that targeted specific problems such as school victimization. Findings across these studies indicated that, on average, the POP strategies led to a statistically significant decline in measures of crime and disorder.

The following programs, which are featured on CrimeSolutions, provide a brief overview of how POP has been implemented and evaluated in the United States. Programs with examined youth-related outcomes or a specific focus on youth are noted; however, most of the research on POP interventions does not focus on youth.

Operation Ceasefire in Boston (first implemented in 1995) is a problem-oriented policing strategy that was developed to reduce gang violence, illegal gun possession, and gun violence in communities. Specifically, the program focused on reducing homicide victimization among young people in Boston (Braga and Pierce, 2005). The program involved carrying out a comprehensive strategy to apprehend and prosecute individuals who carry firearms, to put others on notice that carrying illegal firearms faces certain and serious punishment, and to prevent youth from following in the same criminal path. The program followed the steps of the SARA model, which included bringing together an interagency working group of criminal justice and other practitioners to identify the problem (scanning); using different research techniques (both qualitative and quantitative) to assess the nature of youth violence in Boston ( analysis ); designing and developing an intervention to reduce youth violence and homicide in the city, implementing the intervention, and adapting it as needed ( response ); and evaluating the intervention’s impact ( assessment ). An evaluation of the program found a statistically significant reduction (63 percent) in the average number of youth homicide victims in the city following the implementation of the program. There were also statistically significant decreases in citywide gun assaults and calls for service (Braga et al., 2001). Similarly, another study found a statistically significant reduction (24.3 percent) in new handguns recovered from youth (Braga and Pierce, 2005).

Another program implemented in the same city, the Boston Police Department’s Safe Street Teams (SSTs) , is an example of a place-based, problem-oriented policing strategy to reduce violent crime and includes some components targeting youth. Using mapping technology and violent index crime data, the Boston Police Department identified 13 violent crime hot spots in the city where SST officers could employ community- and problem-oriented policing techniques such as the SARA model. SST officers implemented almost 400 distinct POP strategies in the crime hot spots, which fell into three broad categories: 1) situational/environment interventions, such as removing graffiti and trash or adding or fixing lighting, designed to change the underlying characteristics and dynamics of the places that are linked to violence; 2 ) enforcement interventions, including focused enforcement efforts on drug-selling crews and street gangs, designed to arrest and deter individuals committing violent crimes or contributing to the disorder of the targeted areas; and 3) community outreach/social service interventions, designed to involve the community in crime prevention efforts. Examples of these activities included providing new recreational opportunities for youth (i.e., basketball leagues), partnering with local agencies to provide needed social services to youth, and planning community events. One evaluation (Braga, Hureau, and Papachristos, 2011) found that over a 10-year observation period areas that implemented the SSTs interventions experienced statistically significant reductions in the number of total violent index crime incidents (17.3 percent), in the number of robbery incidents (19.2 percent), and in the number of aggravated assault incidents (15.4 percent), compared with the comparison areas that did not implement the interventions. However, there were no statistically significant effects on the number of homicides or rape/sexual assault incidents. The study also did not examine the impact on youth-specific outcomes.

The Problem-Oriented Policing in Violent Crime Places (Jersey City, N.J.) intervention used techniques from hot spots policing and POP to reduce violent crime in the city. The program and evaluation design followed the steps of the SARA model. During the scanning phase, the Jersey City Police Department and university researchers used computerized mapping technologies to identify violent crime hot spots. During the analysis phase, officers selected 12 pairs of places for random assignment to the treatment group, which received the POP strategies, or to the control group. During the response phase, the 11 officers in the department’s Violent Crime Unit were responsible for developing appropriate POP strategies at the hot spots. For example, to reduce social disorder, aggressive order maintenance techniques were applied, including the use of foot and radio patrols and the dispersing of groups of loiterers. During the assessment phase, the police department evaluated the officers’ responses to the problems, and either adjusted the strategies or closed down the program to indicate that the problem was alleviated. An evaluation found statistically significant reductions in social and physical incivilities (i.e., disorder), the total numbers of calls for service, and criminal incidents at the treatment locations that implemented POP techniques, compared with the control locations (Braga et al., 1999).

COP and POP are two broad policing approaches that, while sharing many characteristics, are still distinct—owing to the focus of their respective approaches. COP’s focus is on community outreach and engagement and does not necessarily rely on analysis methods such as the SARA model. For POP, the primary goal is to find effective solutions to problems that may or may not involve the participation of the community (Gill et al., 2014).

Though COP and POP may differ in their approaches, the end goal is the same in both models. Both are types of proactive policing that seek to prevent crime before it happens. COP and POP also both rely on cooperation from numerous different parties and agencies, including community members (National Research Council, 2018). The two models are similar enough that they often overlap in implementation. For example, the Chicago Alternative Policing Strategy (CAPS) incorporates elements from both models. Using aspects of COP, police officers divide into beat teams and spend most of their time working with community organizations. With regard to POP, CAPS trains officers and residents to use problem-solving techniques that stem from its theoretical basis (Skogan, 1996; Kim and Skogan, 2003).

There are, however, limitations in the research examining the effectiveness of these models. For example, evaluation studies on COP and POP tend to focus on results related to crime and disorder; other outcomes, such as collective efficacy, police legitimacy, fear of crime, and other community-related outcomes are often overlooked or not properly defined (Hinkle et al., 2020; Gill et al., 2014). Exploring other community-related outcomes would be useful, as community involvement is an important component to both models. Further, some researchers have noted specific limitations to the implementation of COP and POP interventions. With regard to COP programs, for example, the definition of “community” is sometimes lacking. This can be an important factor to define, as community may mean something different across law enforcement agencies (Gill et al., 2014). Regarding POP programs, it has been noted that the rigor of the SARA process is limited and that law enforcement agencies may take a “shallow” approach to problem-solving (National Research Council, 2018:193; Borrion et al., 2020). To date, the research on both models has lacked focus on youth; only a few evaluations have focused on youth in either in the implementation process or in examined outcomes (Braga et al., 2001; Gill et al., 2018). Despite these limitations, however, the outcome evidence supports the effectiveness of COP and POP interventions to reduce crime and disorder outcomes.

4.3. Policing Eras

Tiffany Morey and Kate McLean

Policing researchers George Kelling and Mark Moore (1991) have identified three eras of policing in the United States. These eras are discussed below, and are often referred to as the Political Era , the Reform Era , and the Community Era. Each era is defined by differences in seven areas, namely (1) Authorization; (2) Function; (3) Organization; (4) Demand; (5) Environment; (6) Tactics; (7) Outcomes.   [1]

Political Era:  The political era is often referred to as the first era of policing in the United States and it began around the 1840s with the creation of the first bona fide police agencies in America  [2]

This era of policing is marked by the industrial revolution, an influx of immigrants, the formation of large cities, and the abolition of slavery.  The first municipal police departments in the U.S. were formed during this period, including that of New York City (1845) and Chicago (1855).

With the advent of the industrial revolution came a surge in new job opportunities, attracting many individuals – including new immigrants – to growing cities. These intertwined phenomena generated new conflicts, and a rise in crime, in places that were newly-teeming with diverse individuals. The abolition of slavery was also accompanied by the rise of new laws intended to target and criminalize the Black population – as well as vigilante terrorist organizations such as the Ku Klux Klan.  Often growing out of Southern Slave Patrols (the previous form of “law enforcement” in the South), the Klan began to make terrifying appearances throughout the new country, often operating virtually unencumbered.

As its name suggests, the first era of law enforcement was dominated by political calculations, namely the interests of mayors and party machines within growing U.S. cities. Not unlike today, policing during this era was largely under the control of local politicians, who expected municipal police officers to serve their personal agendas, for example, by breaking up protests  ( NOTE:  The word policeman/men is utilized in this era/context, because during this time period, women were not allowed in the profession. If they were accepted, they were permitted only to work with juveniles or women in a “mothering” role). Policing was a well-paid profession with little (or no) required training, and low professional standards; to become an officer of the New York City Police Department, a standard bribe of $500 was accepted. Black policemen were rarely hired in the political era, only making their way into uniform in the late 1800s. When the Civil Rights Act of 1875 was ruled unconstitutional, Black officers all but disappeared from policing until the 1950s.

Reform Era : As the Political Era of policing ended up being laced with corruption and brutality, it was followed by the Reform Era. One police chief was largely at the forefront of this new era, Chief August Vollmer . He is considered the pioneer for police professionalism. August Vollmer was the Chief of Police in Berkeley, California (1905-1932). He had many beliefs about policing that would forever change the world of local law enforcement:

• Candidates who were testing to be in policing had to undergo psychological and intelligence tests
• Detectives would utilize scientific methods in their investigations, through forensic laboratories
• Recruits, for the first time, would attend a training academy (police did not receive any formal training prior to August Vollmer’s arrival)
• Criminal justice should be formalized as an academic discipline and science (Vollmer helped found  the first School of Criminology at the University of California at Berkeley)

Chief August Vollmer saw police officers as “social workers with a badge,” who needed to delve into the causes behind crimes in order to solve the root issue – not just arrest it. [3]  He believed that, in order to rehabilitate offenders, police officers needed to look behind the handcuffs and start looking into the person, and reasons behind the behavior. [4]

Vollmer supported the diversification of police departments during this era, but efforts in this area admittedly fell short.

The Community Era- 1980s to 2000:  In the 1960s and 1970s, the crime rate doubled – not to mention, it was a time of tremendous civil and political unrest. Civil rights movements spread across the U.S., and the police were on the front lines. Media coverage showed white officers brutalizing African Americans,  left-wing student groups, and anti-war protesters, inflaming police-citizen tensions. The U.S. Supreme Court handed down the landmark Miranda v. Arizona  and Mapp v. Ohio  decisions restricting police power. Overall, the “writing was on the wall” – policing had to change. The Community Era of policing began with the intention of involving community members, and addressing their interests, within policing strategies and decisions. Ultimately, this era aspired toward not only improved relations, but more effective policing through collaboration with community members themselves.

This new era of community policing held that police couldn’t act alone; the community must pitch in as well. Whether the problems were a dispute between neighbors, or high crime areas dealing with drug markets and violence, these issues did not develop overnight, and could not be solved by the police alone. Instead, these community problems needed a multi-pronged approach, where the police worked together with the community to solicit their “expertise” as long-term residents so, over time, the issues could be systematically solved. Out-of-the-box thinking was common in this era of community policing, as community stakeholders urged police to consider new, or reconsider old, strategies. For example, the role of police patrol in reducing crime, and increasing citizens’ trust, was explored through two landmark studies (with mixed results). During this time, police candidates started showing up to the application process with Associate’s and Bachelor’s degrees. The ‘old school officers’ sometimes mocked these well-educated candidates, but the landscape was changing and officers needed more thorough training to answer the call.

Problem-oriented policing was an offshoot of community policing, in that it drew on the interests and knowledge of community members, but focused on the problems first. The biggest difference was that problem-oriented policing used a defined process for working towards the solution. The problem was torn apart layer by layer and rectified according to set parameters that had a proven record of working.

The Community Era was also a time for research. Prior to this era, research on crime, police, or criminal justice topics were few and far between. With new federal government funding options available, this era’s missions could be supported through grants and the needed research began. Proof of what worked, what didn’t, and suggestions on how to improve policing were abundant. Without research or studies, policing can become stagnant. The Kansas City, and Newark, Patrol Experiments were examples of such major research undertakings.

The Community Era also gave rise to the more controversial “Broken Windows Theory” and “Broken Windows” or “Zero-Tolerance” policing. Original theorists James Q. Wilson and George Kelling (same as above) postulated that diverse signs of community disorder – such as littler, panhandling, or literal “broken windows” – could encourage first minor, and then major, crimes, if left unaddressed. This was because these small signs of disorder signaled that “no one cared,” and perhaps, that no one would do anything   if larger infractions were committed. Resting on this supposition, Broken Windows policing advocated for “cracking down” on minor criminal infractions, in order to discourage more serious criminals from taking their chances. The legacy of Broken Windows policing is mixed, with commentators crediting this style of law enforcement with the “crime miracle” of the 1990s, and others focusing on the patterns of police abuses that followed.

Community Era Example

“I remember the Community Era very well. I was a new police officer during this time and actually at the forefront of Community Policing and Problem-Oriented Policing. I was the first woman officer at my police department that was pregnant and the administration was open to suggestions when asked what to do with me when my belly expanded. I politely suggested that once I was five to six months pregnant and began to show (and not fit in my uniform or patrol belt anymore), I will be voluntarily transferred to the Crime Prevention Division. With my doctor approving this decision, my belly grew, and I transferred to this new division. I remember hitting the streets and knocking on doors, spewing how great of a panacea Community Policing was. It took some buy-in and with the citizens who ‘bought-it,’ the concept actually became a reality and worked! Months later we had a string of burglaries occurring in a high-crime neighborhood. The detectives, patrol, everyone hit the streets, knocking on doors, questioning everyone, in an attempt to find the criminals responsible. With no avail, I turned to Community Policing. I brought in a mounted police officer and horse. My colleagues chucked and shook their heads in response! What was I thinking?!?! “It was a waste of resources,” they balked! How could a cop on a horse solve this crime? I was glad; I ‘wasted my time,’ because it worked! The officer on the horse brought citizens out of their houses that normally would never have spoken to a police officer normally. The horse was such a spectacle in the neighborhood, that it was the catalyst that caused citizens to not only come out of their houses but to start talking about what and who they had been seeing in and around their neighborhood that did not belong. One such sighting was a vehicle description, which led to criminals responsible for the burglaries. ”

A Fourth Era? The Homeland Security Era, 2001 to Present

On September 11 th , 2001, when terrorists hijacked 4 airplanes and flew them into the World Trade Center buildings and Pentagon, a fourth era of policing, the era of Homeland Security, was said to emerge.  [5] The long-lasting repercussions of this terrorist act would forever change life for Americans, and the daily activities of all policing departments. There is some debate in the field as to the order of policing eras and what they should be called. Some scholars list the policing eras as:

• Pre-Policing Era
• Political Era
• Community Era

While others believe the policing eras are:

• Homeland Security Era

The reality of the 9/11 tragedy was that it did start a new era of policing. In fact, a case could be made for a large dark line that became metaphorically visible on 9/11/01, when the Community Era shifted to the Homeland Security Era as airplanes destroyed America’s feelings of safety.

Policing under Homeland Security is marked by a more focused concentration on intelligence gathering through routine law enforcement activities, as well as increased interest in the centralization of policing. [6]  Scholars have increasingly examined the pros and cons of a national police department in the United States (for example, following the example of Canada’s Royal Canadian Mounted Police.) With the advent of the Homeland Security Era, a new model of centralized organizational control began, due to the need for information dissemination. One of the biggest flaws of 9/11 was the lack of communication between law enforcement agencies. After 9/11, the Department of Homeland Security was developed and one of its first major missions became the dissemination of information and communication. So, while a national police department does not exist in the United States, there are ongoing efforts to better connect law enforcement all all levels through common reporting systems.

Police: Community Policing

Origins and evolution of community policing.

Community policing has been evolving slowly since the civil rights movement in the 1960s exposed the weaknesses of the traditional policing model. Even though its origin can be traced to this crisis in police-community relations, its development has been influenced by a wide variety of factors over the course of the past forty years.

The Civil Rights Movement (1960s). Individual elements of community policing, such as improvements in police-community relations, emerged slowly from the political and social upheavals surrounding the civil rights movement in the 1960s. Widespread riots and protests against racial injustices brought government attention to sources of racial discrimination and tension, including the police. As visible symbols of political authority, the police were exposed to a great deal of public criticism. Not only were minorities underrepresented in police departments, but studies suggested that the police treated minorities more harshly than white citizens (Walker). In response to this civil unrest, the President's Commission on Law Enforcement and the Administration of Justice (1967) recommended that the police become more responsive to the challenges of a rapidly changing society.

One of the areas that needed the most improvement was the hostile relationship separating the police from minorities, and in particular the police from African Americans. Team policing, tried in the late 1960s and early 1970s, developed from this concern, and was the earliest manifestation of community policing (Rosenbaum). In an attempt to facilitate a closer police community relationship, police operations were restructured according to geographical boundaries (community beats). In addition, line officers were granted greater decision-making authority to help them be more responsive to neighborhood problems. Innovative though it was, staunch opposition from police managers to decentralization severely hampered successful team implementation, and team policing was soon abandoned.

Academic interest (1970s). All the attention surrounding the police and the increased availability of government funds for police research spawned a great deal of academic interest. Researchers began to examine the role of the police and the effectiveness of traditional police strategies much more closely. In 1974 the Kansas City Patrol Experiment demonstrated that increasing routine preventive patrol and police response time had a very limited impact on reducing crime levels, allaying citizens' fear of crime, and increasing community satisfaction with police service. Similarly, a study on the criminal investigation process revealed the limitations of routine investigative actions and suggested that the crime-solving ability of the police could be enhanced through programs that fostered greater cooperation between the police and the community (Chaiken, Greenwood, and Petersilia).

The idea that a closer partnership between the police and local residents could help reduce crime and disorder began to emerge throughout the 1970s. One of the reasons why this consideration was appealing to police departments was because the recognition that the police and the community were co-producers of police services spread the blame for increasing crime rates (Skogan and Hartnett). An innovative project in San Diego specifically recognized this developing theme by encouraging line officers to identify and solve community problems on their beats (Boydstun and Sherry).

The importance of foot patrol. It is clear that challenges to the traditional policing model and the assumption that the police could reduce crime on their own, helped generate interest in policing alternatives. However, it was not until the late 1970s that both researchers and police practitioners began to focus more intently on the specific elements associated with communityoriented policing. The major catalyst for this change was the reimplementation of foot patrol in U.S. cities. In 1978, Flint, Michigan, became the first city in a generation to create a city-wide program that took officers out of their patrol cars and assigned them to walking beats (Kelling and Moore). Meanwhile, a similar foot patrol program was launched in Newark, New Jersey.

The difference between these two lay primarily in their implementation. In Flint, foot patrol was part of a much broader program designed to involve officers in community problem-solving (Trojanowicz). In contrast, the Newark Foot Patrol Experiment , which was modeled on the study of preventive patrol in Kansas City, focused specifically on whether the increased visibility of officers patrolling on foot helped deter crime. Results from these innovative programs were encouraging. It appeared that foot patrol in Flint significantly reduced citizens' fear of crime, increased officer morale, and reduced crime. In Newark, citizens were actually able to recognize whether they were receiving higher or lower levels of foot patrol in their neighborhoods. In areas where foot patrol was increased, citizens believed that their crime problems had diminished in relation to other neighborhoods. In addition, they reported more positive attitudes toward the police. Similarly, those officers in Newark who were assigned to foot patrol experienced a more positive relationship with community members, but, in contrast to Flint, foot patrol did not appear to reduce crime. The finding that foot patrol reduced citizen fear of crime demonstrated the importance of a policing tactic that fostered a closer relationship between the police and the community.

As foot patrol was capturing national attention, Herman Goldstein proposed a new approach to policing that helped synthesize some of the key elements of community policing into a broader and more innovative framework. Foot patrol and police-community cooperation were integral parts of Goldstein's approach, but what distinguished problem-oriented policing (POP) was its focus on how these factors could contribute to a police officer's capacity to identify and solve neighborhood problems. By delineating a clear series of steps, from identifying community problems to choosing among a broad array of alternative solutions to law enforcement, Goldstein showed how increased cooperation between the police and community could do more than reduce fear of crime. An intimate familiarity with local residents could also provide the police with an invaluable resource for identifying and solving the underlying causes of seemingly unrelated and intractable community problems. With its common emphasis on police-community partnerships, parts of the philosophy of problem-oriented policing were readily incorporated into ideas about community policing.

The beginnings of a coherent community policing approach (1980s). Interest in the development of community policing accelerated with the 1982 publication of an article entitled "Broken Windows." Published in a national magazine, The Atlantic Monthly , the article received a great deal of public exposure. Drawing upon the findings of the Newark Foot Patrol Experiment , James Q. Wilson and George L. Kelling constructed a compelling and highly readable argument challenging the traditional crime-fighting role of the police, and exploring the relationship between social disorder, neighborhood decline, and crime.

According to Wilson and Kelling, officers on foot patrol should focus on problems such as aggressive panhandling or teenagers loitering on street corners that reduce the quality of neighborhood life. Similar to a broken window, the aggressive panhandler, or the rowdy group of teenagers, represent the initial signs of social disorder. Left unchecked they can make citizens fearful for their personal safety and create the impression that nobody cares about the neighborhood. Over time, this untended behavior increases the level of fear experienced by lawabiding citizens, who begin to withdraw from neighborhood life. As residents retreat inside their homes, or even choose to leave the area altogether, local community controls enervate and disorderly elements take over the neighborhood. Eventually, this process of neighborhood deterioration can lead to an increase in predatory crime. Wilson and Kelling argue that by patrolling beats on foot and focusing on initial problems of social disorder, the police can reduce fear of crime and stop the process of neighborhood decay.

Goldstein's work and Wilson and Kelling's article sparked widespread interest in problem solving, foot patrol, and the relationship between the police and the community, all of which were becoming broadly associated with community policing. Police departments were quick to seize upon the ideas and publicity generated by these scholars, and in the 1980s they experimented with numerous problem-and communityoriented initiatives. In 1986 problem-oriented policing programs were implemented in Baltimore County, Maryland, and Newport News, Virginia (Taft; Eck and Spelman). In Baltimore County, small units composed of fifteen police officers were assigned to specific problems and responsible for their successful resolution. In Newport News, the police worked with the community to identify burglaries as a serious problem in the area. The solution involved the police acting as community organizers and brokering between citizens and other agencies to address the poor physical condition of the buildings. Ultimately the buildings were demolished and residents relocated, but more importantly problem-oriented policing demonstrated that the police were capable of adopting a new role, and it did appear to reduce crime (Eck and Spelman).

An initiative to reduce the fear of crime in Newark and Houston through different police strategies, such as storefront community police stations and a community-organizing police response team, was successful in reducing citizens' fear of crime (Pate et al.). Interestingly, the results in Houston suggested that generally the program was more successful in the areas that needed it least. Whites, middle-class residents, and homeowners in low-crime neighborhoods were more likely to visit or call community substations than minorities, those with low incomes, and renters (Brown and Wycoff).

These studies further catalyzed interest in community policing and problem solving, and from 1988 to 1990 the National Institute of Justice sponsored the Perspectives on Policing Seminars at Harvard University's Kennedy School of Government. Not only did this help popularize these innovations in policing, but it helped scholars and practitioners refine and synthesize the mixture of ideas and approaches labeled community-and problem-oriented policing. One policing seminar paper in particular received a great deal of scholarly attention. The Evolving Strategy of Policing , by George Kelling and Mark Moore, summarized the history of policing and identified what was unique about recent developments in the field. In contrasting three different policing approaches and finishing with the advent of the "community problem-solving era," Kelling and Moore appeared to be sounding a clarion call, announcing the arrival of a complete paradigm shift in law enforcement.

In the face of such bold proclamations, it is unsurprising that scholars began to examine community policing more critically, and queried whether it could fulfill its advocates' many promises. Contributors to an edited volume on community policing entitled Community Policing: Rhetoric or Reality? noted that without a workable definition of community policing, its successful implementation was difficult. They also suggested that community policing might just be "old wine in new bottles," or even a communityrelations exercise employed by police departments to boost their legitimacy in the eyes of the public (Greene and Mastrofski). The outgrowth of these thoughtful criticisms was to encourage researchers to design more rigorous methodological studies that could evaluate the effects of community policing more clearly.

Community policing as a national reform movement (1990s and beyond). By the 1990s, community policing had become a powerful national movement and part of everyday policing parlance. Encouraged by the federal funds made available through the Office of Community Oriented Policing Services (COPS), police departments across the country shifted their attention toward implementing community policing reforms. Annual conferences on community policing became commonplace, and researchers began to study community-policing programs in cities all over America. Besides the availability of funds and promising research findings, the political appeal of community policing and its close affinity to long-term trends in societal organization contributed to the widespread acceptance of community policing (Skogan and Hartnett).

Given the large concentration of African Americans and Hispanics in American cities, groups who have historically been engaged in a hostile relationship with the police, an approach to law enforcement that promised to improve police-community relations by working with, rather than targeting, racial and ethnic minorities held great appeal for local politicians concerned with pleasing their constituents. In addition, community policing reflected a more general underlying trend in the structure, management, and marketing practices of large organizations. In contrast to rigid bureaucracies and their dependence on standard rules and policies, decentralization created smaller, more flexible units to facilitate a speedier and more specialized response to the unique conditions of different organizational environments. Rather than emphasizing control through a strict organizational hierarchy, management layers were reduced, organizational resources were made more accessible, and both supervisors and their subordinates were encouraged to exercise autonomy and independence in the decision-making process. Finally, the extent to which consumers were satisfied with the market produce, in this case police services, became an important criteria for measuring police performance (Skogan and Hartnett).

At the outset of the twenty-first century, the momentum behind community policing shows no signs of slowing down. Even though police departments may have been slow to adopt all the philosophical precepts, tactical elements, and organizational changes commensurate with the entire community-policing model, its slow and steady evolution suggests that it is a permanent fixture on the landscape of American policing (Zhao and Thurman).
