PROBLEM ORIENTED POLICING

MAY CONTAIN MARKUP

Herman Goldstein

In his seminal work on problem-oriented policing, Herman Goldstein emphasizes the importance of addressing the root causes of crime and disorder within communities. Goldstein’s book provides a framework for law enforcement agencies to shift their focus from reactive responses to proactive measures aimed at preventing recurring issues.

The core concept of problem-oriented policing lies in identifying specific problems within a community, analyzing the underlying factors contributing to those problems, and developing tailored strategies to mitigate them. By working collaboratively with community members, local organizations, and other stakeholders, law enforcement can implement sustainable solutions that address the root causes of crime and disorder.

Goldstein’s book serves as a guide for police departments looking to adopt a more proactive and community-centered approach to policing. By encouraging officers to engage with the community, gather data on recurring issues, and implement evidence-based strategies, problem-oriented policing offers a promising alternative to traditional law enforcement practices.

Overall, Herman Goldstein’s book on problem-oriented policing provides valuable insights and practical tools for law enforcement agencies seeking to build safer and more resilient communities through proactive problem-solving strategies.

The Special Constable in Scotland: Understanding the motivations, expectations and the role of the Special Constabulary within Police Scotland

By Andrew Wooff, Graeme Dickson, Jamie Buchan

This project aims to support Police Scotland’s ‘Policing 2026’ strategy by enhancing the understanding of the motivations, roles and expectations of Special Constables, a group of people largely absent from academic policing discourse in Scotland. This group of volunteers represents an important resource in contemporary policing, particularly against the backdrop of economic constraint (Bullock, 2014). In recent years, the numbers of Special Constables in Scotland – as with the rest of the UK – have been in a general decline (Home Office, 2018; Police Scotland, 2018). This project sought to examine the nature of the Special Constabulary as a volunteering resource in Scotland, considering the way(s) that the motivations, expectations and management of Special Constables could be understood and improved. As such, the report explores the following questions: ● What motivates Special Constables to volunteer for Police Scotland and does this vary depending on how long they have been a Special Constable? ● To what extent does the role of a Special Constable vary by geography and local policing area? ● What are the expectations of Police Scotland for their Special Constabulary and does this vary by geography? ● What could be done to improve the current pathways between Special Constables and regular officer recruitment? ● What, if anything, will help support the development and retention of Special Constables in Police Scotland?

Forty years of problem-oriented policing: A review of progress in England and Wales

By Karen Bullock, Aiden Sidebottom, Rachel Armitage , Matthew P.J. Ashby, Caitlin Clemmow, Stuart Kirby, Gloria Laycock and Nick Tilley

This article analyses and critically reflects on the position of problem-oriented policing within England and Wales. Problem-oriented policing is a framework for improving police effectiveness. Its adoption has consistently been shown to be associated with sizable reductions in a wide range of crimes and public safety issues. However, many studies also find that problem-oriented policing is difficult to embed and sustain within police organisations. This article draws on the experiences and perspectives of 86 informed stakeholders to critically examine the position and practice of problem-oriented policing 40 years after its original formulation by Herman Goldstein in 1979. We argue that despite evidence of renewed interest in problem-oriented policing, the approach is not habitually conducted within police organisations in England and Wales. Where it is conducted, the practice of problem-oriented policing is found to lack discipline, the processes tend not to be faithfully followed, and there are weaknesses at all stages of the process. Implications of the findings for future research and police practice are discussed.

Problem-oriented policing in England and Wales: barriers and facilitators

By Karen Bullock, Aiden Sidebottom, Rachel Armitage, Matthew P.J. Ashby, Caitlin Clemmow, Stuart Kirby, Gloria Laycock & Nick Tilley

Evidence shows that the application of problem-oriented policing can be effective in reducing a wide range of crime and public safety issues, but that the approach is challenging to implement and sustain. This article examines police perceptions and experiences regarding organisational barriers to and facilitators of the implementation and delivery of problem-oriented policing. Drawing on surveys of (n = 4141) and interviews with (n = 86) police personnel from 19 police forces in England and Wales, we identify five key barriers and facilitators to problem-oriented policing: leadership and governance, capacity, organisational structures and infrastructure, partnership working and organisational culture. These factors provide important indicators for what police organisations need to do, or need to avoid, if they are to successfully embed and deliver problem-oriented policing. The article generates critical information about the processes that drive change in police organisations and offers recommendations for police managers who may wish to implement or develop problem-oriented policing. The paper also proposes a research agenda aimed at addressing evidence gaps in our understanding of the implementation and sustenance of problem-oriented policing.

Detroit Project Safe Neighborhoods: Final Evaluation Report

By Edmund F. McGarrell Stephen Oliphant Alaina De Biasi Julie M. Krupa

Project Safe Neighborhoods (PSN) is a national program that seeks to reduce levels of gun and gang crime, and violent crime generally. The Eastern District of Michigan has participated in PSN since its outset in 2001. Although the Eastern District has included attention to violent crime in multiple communities, Detroit has been a primary target area throughout the years of PSN. PSN is a grant supported program by the Bureau of Justice Assistance, U.S. Department of Justice. This report summarizes the implementation and impact of the grant supported program that was funded in fiscal year 2018. During this period, the PSN team focused on Detroit Police Department’s 9th precinct, with targeted enforcement in specific hotspot areas. PSN Detroit relied upon a multi-agency team and followed a comprehensive strategy of targeted enforcement, intervention with at-risk individuals, and youth-focused prevention. The PSN initiative, like law enforcement operations nationally, was significantly affected by the COVID-19 pandemic. This added to the complexity of the evaluation and makes some of our research findings tentative. With this qualification in mind, we find support for the positive impact of PSN. Specifically, following the implementation of PSN in the 9th precinct until the shutdowns associated with the impact of the pandemic in March 2020, the 9th precinct witnessed a decline from 13.6 shooting victimizations per month to 11.9 per month (-12.5%). During this same period, Detroit’s other precincts witnessed a total increase from 63.8 to 72.6 (+13.7%), or an average per precinct increase from 6.3 to 7.3 per month. When examining the specific hotspot areas, we observed a decline of 2.6 shooting victimizations per month in the hotspot zone when compared to a comparison area drawn from parts of the city that did not experience PSN.

These trends were interrupted by the onset of the pandemic, as well as the period of social unrest and protest following the death of George Floyd in Minneapolis. The pandemic had a serious effect in Detroit with the Police Department experiencing significant personnel losses due to illness and quarantine, and the suspension of court operations. As was the case nationally, violent crime increased in Detroit and in the 9th precinct in 2020 and the first half of 2021. In the last quarter of 2021 and the first quarter of 2022, the 9th precinct again witnessed welcome declines in shooting victimizations. These declines were also observed citywide and were particularly noteworthy in the specific PSN target areas within the 9th precinct. The PSN team’s strategy of supporting a focused multi-agency enforcement team, while leveraging comprehensive intervention and place-based strategies appears to have enhanced public safety in Detroit.

Enhanced Community Engagement and Community Policing: A Review of York Regional Police Anti-Racism Practice

By Foster & Associates

  In January 2022 York Regional Police (YRP or ‘the Service’) contracted Foster & Associates to ‘review and report on the provision of recommendations and best practices to enable York Regional Police to build and improve relationships with Black, Indigenous and other racialized communities’. The York Regional Police Board (YRPB or ‘Board’) identified recommendations made at its meeting on September 23, 2022 with the Black community and developed a list of 51 recommendations in total, 43 of which fell within the responsibilities of the Service. A preliminary document was tabled by the Chief with the Board on April 14, 2021 that identified activities already undertaken and in progress, signaling the intent to continue consulting with the Black community to advance positive change that builds trust and confidence in policing

The place-based effects of police stations on crime: Evidence from station closures

By Sebastian Blesse a, André Diegmann

Many countries consolidate their police forces by closing down local police stations. Police stations represent an important and visible aspect of the organization of police forces. We provide novel evidence on the effect of centralizing police offices through the closure of local police stations on crime outcomes. Combining matching with a difference-in-differences specification, we find an increase in reported car theft and burglary in residential properties.and Our results are consistent with a negative shift in perceived detection risks and are driven by heterogeneous station characteristics. We can rule out alternative explanations such as incapacitation, crime displacement, and changes in police employment or strategies at the regional level. We argue that criminals are less deterred due to a lower visibility of the local police.

DARE to Say No: Police and the Cultural Politics of Prevention in the War on Drugs Max Felker-Kantor1

In the fall of 1983, the Los Angeles Police Department sent police officers into elementary schools to teach the Drug Abuse Resistance Education (DARE) Program. Within a decade DARE had become the nation’s preeminent anti-drug education program. Yet the DARE program accomplished much more than teaching kids to resist drugs. DARE shifted the responsibility of preventing drug use from social and public-health policy to local, police-led, educative projects that taught personal responsibility, the value of morally strengthened families, and respect for the authority of the police. By stressing the consequences of poor behavior and demanding respect for law and order, DARE attempted to cultivate popular consent for policies that divorced drug use from social and economic conditions. DARE’s approach helped justify reductions in social welfare spending and the expansion of policing and incarceration during the 1980s and 1990s.

Zero Tolerance in Catalonia. Policing the Other in Public Space

By  Martin Lundsteen &  Miquel Fernández González 

Recent studies have argued for more nuanced understandings of zero tolerance (ZT) policing, rendering it essential to analyze the significance and actual workings of the policies in practice, including the context in which they are introduced. This article aims to accomplish this through a comparison of two case studies in Catalonia: one in the neighborhood of Raval in Barcelona and one in Salt—a municipality in the comarca (or county) of Girona. We identify a transformation in the use of ZT policies in Catalonia and a con‑tradiction between their social effects and proclaimed objectives. This article attempts to address how specific sociocultural groups gain power and privilege from these policies. The main argument is that a set of commonsensical ideas have become hegemonic, which allows and naturalizes certain sociocultural practices in urban space, while persecuting oth‑ers, fundamentally pitting two categories against each other: the desired civil citizen and the undesirable and uncivil stranger

Community policing does not build citizen trustin police or reduce crime in the Global South

By Graeme Blair et al.

More than one-fourth of the world's population lives in conditions of in-security because of high levels of crime and violence, especially in the Global South. Although the police are central to reducing crime and violence, they are also often per-petrators of unjust harm against citizens.We investigated the effects of community policing, a set of practices designed to build trust between citizens and police, increase the co-production of public safety, and reduce crime. Community policing is meant to improve outcome by increasing engagement between citizens and police through increased foot patrols, community meetings, and the adoption of problem-oriented policing strat-egies that address concerns raised by citizens.When cooperation leads to effective police responses, this approach reinforces citizen trust and facilitates further cooperation, creating a virtuous cycle. Community policing has beenimplementedaroundtheworldoneverycon-tinent. However, although there is evidence for its positive effects in rich countries, there is no systematic evidence about whether com-munity policing effectively generates trust and reduces crime in the Global South.

Goldilocks and the three “Ts”: Targeting, testing,and tracking for “just right” democratic policing

By Lawrence W. Sherman

Police are often criticized fordoing “too much” or “too little” policing in various sit-uations. These criticisms amount to testable hypothe-ses about whether “less” force, or intensity, or enforce-ment would have been enough, or whether “more” was needed. The rise of evidence-based policing provides a starting point for public dialogues about those hypotheses, in ways that could help to build police legitimacy.Such dialogues can be focused on the questions posed by the three “Ts”: (1) Is police actiontargetedin a way that is proportionate to the harm that it can prevent?(2) Has the action been tested and found effective with the kinds of targets, and their levels of harm, where it is being used? (3) Is police actiontrack to ensure it is delivered in the way that has been tested, and in compli-ance with relevant legal requirements? In this lecture, I frame the issue as follows:Can more widespread use of better research evidence on targeting, testing, and tracking police actions, shared more clearly among the public and police, help reduce the wide range of oscillation between over-policing and under-policing?PolicyImplications:Theuseofthesequestionsinpub-lic dialogue would be especially relevant to the three biggest threats to police legitimacy in the aftermath ofGeorge Floyd’s murder: (A) police killing people, (B)police stopping people, and (C) police under-patrolling 176SHERMANhigh-crime hot spots (while over-patrolling low-crime areas). One result of applying the three-Ts questions to these threats, for example, could be the end of the vast overuse of stop and search in low-violence areas. At The same time, this approach could also lead to reduc-tions in homicide by increasing stops in highest vio-lence hot spots. Such changes could demonstrate how the “Goldilocks principle” for the three Ts could get policing closer to “just right” for each place and person being policed.

Policing Without the Police? A Review of the Evidence

By Charles Fain Lehman

In the wake of the death of George Floyd and the summer of protests and riots that followed, left-wing activists and politicians have called not simply for reforms to policing, but for its abolition. In order to eliminate the possibility of wrongful killing of civilians, these advocates say, we should defund police departments, reroute their budgets to social services, and replace beat cops with unarmed civilian alternatives wherever possible. In the first half of this brief, I outline why such proposals would be a disaster for public safety. In short, they:

  • Have little basis in evidence;

  • Would increase the risk posed to civilian employees;

  • Would diminish the crime-reduction benefits of current police work; and

  • Would have little impact on the size, and therefore effect, of social welfare spending.

While replacing the police is a misguided idea, that does not mean that lawmakers should dismiss altogether the idea of nonpolice crime-fighting tools. Indeed, there are several evidence-based, effective means to mitigate crime through channels other than more police work. These complementary tools can help relieve stress on overtaxed and understaffed police forces. In the second half of this report, I lay out the evidence behind three options:

  • Reducing crime through changes to the built environment, such as cleaning up vacant lots and green public spaces;

  • Using “nonpolice guardians,” such as neighborhood watches and CCTV cameras, to extend the police’s reach;

  • Targeting problematic alcohol use, a major cause of crime.

Open Drug Scenes and the Merging of Policing Practice and Research: a pracademic approach

By Mia-Maria Magnusson

Policing research has had an upswing as the evidence-based policing movement has grown stronger and entered police practises worldwide. Within the evidence-based policing (EBP) approach, practically and academically skilled individuals, pracademics, have attracted attention as facilitating the merging of policing practice and research.

Using principles from EBP, and with a special focus on translating between policing practice, policy and research, this thesis aims to explore the characteristics of illicit drug markets with a place-based focus and to link this to the enhancement of EBP in Sweden. The theoretical base of the thesis is drawn from disorganization theory, routine activity theory and situational action theory, and these theories are combined with empirical studies from the research field of drug markets. This thesis argues for making use of pracademics to bridge the research-practice gap, a focus on ODSs, and the testing and tracking of methods such as hot spots policing, with an emphasis on properly implemented evidence-based methods and on the goals of enforcement strategies as a means of improving the effectiveness of drug-market policing.

Exploring Police Integrity: Novel Approaches to Police Integrity: Theory and Methodology

Edited by Sanja Kutnjak Ivković and M. R. Haberfeld

This work provides an innovative new look at police ethics, including results from an updated version of the classic Police Integrity Questionnaire, including new social and technological advances. It aims to push the study of police research further, expanding on and testing police integrity theory and methodology, the relationship between community and integrity, and the influence of multiculturalism and globalization on policing and community attitudes.

This work brings together experienced scholars who have used the police integrity theory and the accompanying methodology to measure police integrity in eleven countries, and provide advance and sophisticated explorations of the topic. Organized into three thematic sections, it explores the testing methodology for international comparisons, insights into police-community relations, and explores police subcultures.

Changing Police Culture: Policing in a Multicultural Society

By Janet B. L. Chan

Police culture is often considered as both a cause of police deviance and an obstacle for police reform. In this study of police racism and police reform in Australia, Janet Chan provides a critical assessment of police initiative in response to the problem of policeSHminorities relations. The book examines the dynamics of change and resistance within an organization and captures the complexity and unpredictability of the change process. It questions the utility of the traditional conception of police culture and proposes a new framework for understanding the interrelationships among the structural conditions of police work, police cultural knowledge, and police practice. A highly original and valuable contribution to policing studies and studies of organizational reform, the book is both empirically rich and theoretically informed.

SAFE Charlotte: Alternative Response Models and Disparities in Policing

By Molly M. Simmons, Daniel Tapia, Richard H. Donohue, Denis Agniel, Matthew L. Mizel, Lisa Wagner, Amanda Charbonneau, Danielle Sobol

Under contract with Charlotte, North Carolina, the authors evaluated three of the six policing and public-safety recommendations in the city's SAFE Charlotte: Safety and Accountability for Everyone report. Recommendation 2 is about developing ways to implement a civilian response for low-risk duties. Recommendation 3 requested independent analysis of police–community member contact to determine the extent to which racial/ethnic bias is evident in policing in Charlotte. Recommendation 4 states that Charlotte's Community Policing Crisis Response Team should be expanded, and a specialized civilian responder model should be explored for those experiencing mental health crisis and homelessness.

  • The authors recommend two pilot programs: (1) a new team of clinicians who would deploy in pairs to provide services that could help address substance abuse, mental health, and homelessness and (2) a program that would delegate low-risk, low-priority calls to nonspecialized civilian responders. The estimated costs for the clinician team pilot would be approximately $850,000 for the first year. The estimated costs for the pilot of civilian responders for low-risk, low-priority calls would be approximately $1.4 million to $1.85 million for the first year. Local stakeholders should be involved in every aspect of development and implementation of all potential programs — from hiring to uniforms. The authors analyzed stop data, arrest data, and complaint data and found that Black residents in Charlotte were more likely to be stopped both as a driver and as a pedestrian and, when stopped, were more likely to be arrested.

The Law Enforcement Response to Homelessness: Identifying High-Priority Needs to Improve Law Enforcement Strategies for Addressing Homelessness

By Sean E. Goodison, Jeremy D. Barnum, Michael J. D. Vermeer, Dulani Woods, Siara I. Sitar, Brian A. Jackson

Police often are the first (and sometimes the only) point of government contact for persons experiencing homelessness (PEH). Although it has been common for police to rely on traditional law enforcement powers in dealing with homelessness, many agencies have moved away from arrest-focused methods in favor of approaches that are designed to foster positive relationships with PEH, assess individual needs of each person or area, and guide homeless or unsheltered individuals to the services they require.

To better understand the potential challenges of the law enforcement response to homelessness, the RAND Corporation and the Police Executive Research Forum, on behalf of the National Institute of Justice, convened a workshop of practitioners and researchers to discuss current law enforcement responses to homelessness and identify the highest-priority needs to support and improve existing efforts. During this meeting, four major themes were identified. First, there is a common set of factors underlying homelessness that law enforcement can address. Second, homelessness and overall health and wellness are deeply intertwined issues that should be treated together. Third, effective responses require the collaboration of stakeholders across governments, the private sector, and the community. Finally, acquiring and sharing data is necessary to understand the nature and scope of homelessness in each jurisdiction and to measure the effect of any implemented strategies. All four of these themes are vital to understanding the current challenges confronting the implementation of innovative police responses to homelessness.

Would Law Enforcement Leaders Support Defunding the Police? Probably -- IF Communities Ask Police to Solve Fewer Problems

By Michael J. D. Vermeer, Dulani Woods, Brian A. Jackson

Recent nationwide protests against police use of force and perceptions of systemic racism in law enforcement in the United States have sparked renewed conversation about problems in the U.S. criminal justice system. Much of this conversation has been focused on the idea of "defunding the police." In this Perspective, the authors describe police leaders' and practitioners' views on defunding the police — that is, budgeting less money for police and more for other public safety strategies — and explain why revisiting the role of law enforcement in society could have broader appeal than some think. To do this, the authors draw on experience in workshops held over the past seven years by the Priority Criminal Justice Needs Initiative. In these workshops, police leaders and practitioners have voiced frustration with being the default party that is expected to respond to many complex social problems, such as homelessness, substance use, and mental health crises. Practitioners argue that nonenforcement strategies are often more effective than policing in solving many of these problems. Therefore, the authors suggest that there might be significant law enforcement support for some "defunding" strategies — as long as these efforts relieve some of the unrealistic expectations on police. The authors also describe current police functions that could be reassigned to other community partners, discuss factors that communities must consider if they choose to reallocate police functions, and note evidence of broader support for such reforms in the general population.

Real-Time Crime Centers in Chicago: Evaluation of the Chicago Police Department's Strategic Decision Support Centers

By John S. Hollywood, Kenneth N. McKay, Dulani Woods, Denis Agniel

Strategic Decision Support Centers (SDSCs) are the Chicago Police Department's district-level real-time crime centers, launched in January 2017 and expanded in 2018. They serve as command and control centers for staff to gain awareness of what is happening in their districts and decide on responses. SDSCs support daily and weekly planning meetings and provide near–real-time support for detecting, responding, and investigating crimes as they occur. Their objectives are to improve districts' abilities to reduce crime, hold offenders accountable, improve officer safety, and reduce service times.

In this report, the authors evaluate the processes, organizational structures, and technologies employed in the SDSCs. They also assess the extent to which the introduction of SDSCs was associated with reductions in crime levels in the districts. They find that SDSCs are a promising tool for supporting crime reduction. According to the authors' models, a district that adds an SDSC can expect to see reductions in at least some of the ten types of major crimes modeled, including shootings, robbery, burglary, and criminal sexual assault.

More broadly, the authors see SDSCs as a promising model for improving law enforcement agencies' awareness of their communities, improving their decision-making, and carrying out more effective and more efficient operations that lead to crime reductions and other policing benefits.
