This essay argues for increased recognition and support of community-based violence intervention (CVI) as an integral element of public safety strategies to reduce community violence. While the work of CVI has long been important to the communities in which they were created, the unprecedented rise in gun violence since 2020, coupled with growing recognition from community members, elected officials and law enforcement that violence reduction strategies rooted in community are necessary for community safety, make this work more vital than ever. Achieving sustained reductions in violence will require not just the incorporation of CVI into public safety plans, but also the intentional investment in an ecosystem of human capital development and community stability for the people and neighborhoods most impacted by violence.

Community violence, or interpersonal violence between non-intimate partners that occurs in public places, is rooted in poverty and trauma, which, particularly in the United States, are undergirded by racial capitalism and white supremacy. Community-based outreach has been well documented as an integral strategy for reaching historically marginalized and disenfranchised populations in multiple fields. Community-based violence intervention (CVI) approaches that utilize outreach workers—professionals who identify and engage youth and adults who have a high risk of violence involvement—have the potential to quell violence in cities around the country. Indeed, the Biden-Harris Administration has not only highlighted CVI as an important element of community safety, but it has also committed federal dollars to CVI programs.

This amplification of CVI as a promising violence-reduction approach has also led to greater scrutiny of the various challenges these initiatives face in their implementation and operation, capacity, staffing needs, and the contexts for which they are employed. Without a more precise grasp of the elements that make these approaches effective and the challenges that must be mitigated for successful implementation and operation, outreach-based violence intervention programs, regardless of the intent or passion of the staff, may fail to achieve their goal of significantly reducing violence in their communities. However, if properly funded, supported, implemented, and evaluated, CVI has the potential to expand the paradigm of community safety without furthering over-reliance on law enforcement and the criminal legal system. This report seeks to fill gaps in our understanding of how best to implement, support, and sustain outreachbased CVI efforts by synthesizing existing literature and drawing on interviews with over a dozen CVI program leaders with deep expertise in the field.

Outreach-Based CVI Program Models and Their Needs

The majority of outreach-based CVI programs today are individualized interventions that operate as independent community-based organizations. They require identifying individuals who are most likely to engage in violence, through community contacts, law enforcement, research, or voluntary participation, and then getting proximate to these individuals, building relationships and relentlessly pursuing connection in order to link them to resources, such as case management, therapy, professional development, or substance abuse treatment that will allow them to make different choices.

Some of these organizations use the health care system, rather than the community, as an entry point to locate those who are most affected by violence and who may be caught in violent cycles. (continued)

In the 2010s, viral videos of seemingly routine police encounters depicting tragedy have sent shockwaves through both communities and law enforcement agencies across the country, setting off a national conversation on the relationship communities have with law enforcement. At the national level, these encounters have coincided with reduced public confidence in American policing, particularly among youth and minority populations. While low levels of trust have existed in certain communities throughout history, the most recent wave of high-profile incidents has prompted widespread calls to meaningfully address issues of community concern, such as officer-involved shootings and excessive force, discriminatory policing, aggressive crime fighting strategies, and accountability for misconduct. Across the nation, law enforcement leaders, academics, and government officials have seemingly reached a consensus that addressing such issues with a focus on public trust and legitimacy is integral to fair and effective public safety in an increasingly diverse nation. The response by governments, law enforcement executives, community groups, and technical advisors to the challenge of mending police-community relations has been significant. In the aftermath of unrest in Ferguson, Missouri, and elsewhere, then President Barack Obama established the Task Force on 21st Century Policing to identify policing practices that promote public safety and build community trust in law enforcement. The Final Report of the President’s Task Force on 21st Century Policing, published in May 2015, offered several recommendations, including many relating to public trust, procedural justice, and legitimacy; accountability and transparency; community policing efforts; and the inclusion of community members in policy development, training programs, and review of force incidents. In addition, the task force’s report recommended that civilian oversight of law enforcement be established in accordance with the needs of the community and with input from local law enforcement stakeholders.4 Civilian oversight of law enforcement can contribute significantly to the implementation and institutionalization of many of the task force’s recommendations and further the development of public trust, legitimacy, cooperation, and collaboration necessary to improve police-community relations and enhance public safety. At its core, civilian oversight can be broadly defined as the independent, external, and ongoing review of a law enforcement agency and its operations by individuals outside of the law enforcement agency being overseen. Civilian oversight may entail, but is not limited to, the independent investigation of complaints alleging officer misconduct, auditing or monitoring various aspects of the overseen law enforcement agency, analyzing patterns or trends in activity, issuing public reports, and issuing recommendations on discipline, training, policies, and procedures. Taken together, these functions can promote greater law enforcement accountability, increased transparency, positive organizational change, and improved responsiveness to community needs and concerns. By acting as an independent and neutral body reviewing the work of the law enforcement agency and its sworn staff, civilian oversight of law enforcement offers a unique element of legitimacy that internal accountability and review mechanisms simply cannot. Similarly, a civilian oversight agency’s impartiality, neutrality, and adherence to findings of fact can alleviate officer skepticism in internal systems and bolster procedural fairness within the law enforcement agency as a whole. The organizational structure and authority of civilian oversight agencies in the United States varies widely. While civilian oversight agencies can be broadly categorized into review-focused, investigation-focused, or auditor/ monitor-focused models, no two oversight agencies are identical. Effective civilian oversight systems will reflect the particular needs of their local partners and incorporate feedback from community members, law enforcement and their unions, and government stakeholders in order to achieve the most sustainable and appropriate structure. As the field of civilian oversight grows in sophistication, cities are frequently combining various aspects of traditional oversight models to produce hybrid forms best suited for their local context. As a whole, this report, the nine case studies, and the online toolkit are part of NACOLE’s work to expand, improve, and assist civilian oversight of law enforcement efforts throughout the country. This work provides comprehensive guidance for oversight practitioners, law enforcement, community organizations, and local officials to further develop effective civilian oversight. Additional research, guidance, and understanding will be necessary as the field of oversight continues to evolve and grow.

This report is about two opposite but related issues: (1) the use of drones by police agencies to protect public safety and (2) the use of drones by malicious actors to commit various crimes such as acts of terrorism. Thus, the story of drones is about two radically different sides of the same coin. This report should be seen as two separate reports. The bulk of the document, chapters 1 and 2, provides guidance to police and sheriffs’ departments about how to identify the ways in which drones could facilitate their work and how to create a drone program to accomplish those goals. The remainder of the document, chapter 3, is about the malicious use of drones. As of early 2020, the United States is extremely vulnerable to drone attacks because only in late 2018 were federal law enforcement agencies given the legal authority to use the most effective types of technologies to detect and mitigate drone threats. Local police and sheriffs’ departments still are unable to purchase or use most counter-drone technologies because of concerns they might break the law when employing them and the danger of interference with air traffic in the National Airspace System. This is not merely oversight by Congress and federal agencies; there are important reasons for limiting drone detection and mitigation technologies. Careless or unskilled use of these technologies could result in disaster. For example, technologies that use radio signals to jam an incoming malicious drone or seize control of it, improperly used, might interfere with radio signals used by commercial or private airplanes or air traffic controllers. A number of federal and local law enforcement agencies have begun to explore counter-drone strategies at major events and mass gatherings such as the Super Bowl. But this work is still developing. Federal, state, and local lawmakers and government officials, including law enforcement officials, should accelerate their efforts to address these issues as soon as possible. The drone strikes against oil facilities in Saudi Arabia in September 2019, which temporarily disrupted approximately half of that kingdom’s oil production capacity, demonstrate how much harm can be done by the malicious use of drones. The United States must not wait until it suffers a drone attack to undertake large-scale efforts to develop strategies by law enforcement agencies at all levels of government for (1) identifying drone threats and (2) mitigating drone threats in real time.

The research behind this report In 2018 and 2019, the Police Executive Research Forum (PERF), with support from the U.S. Department of Justice’s (DOJ) Office of Community Oriented Policing Services and the U.S. Department of Homeland Security’s (DHS) Office for State and Local Law Enforcement, conducted research, disseminated a survey of law enforcement agencies, and hosted a two-day forum to discuss police use of drones and the police response to the threat of drones being used maliciously. This project consisted of three major components: (1) an informal survey of 860 law enforcement agencies nationwide; (2) interviews with more than 50 police executives and personnel in agencies that operate a drone program or have plans to implement one; and (3) a two-day national conference in which police executives, federal stakeholders, and other experts from across the country discussed and debated the considerations associated with police use of drones. The purpose of this report is to assist police agencies interested in establishing their own drone programs.1 Key findings and recommended practices This report is divided into three chapters:

1. Pre-Implementation Considerations

2. Establishing a Drone Program

3. Malicious Use of Drones

This report focuses on the police response to antisocial behaviour. It also highlights examples of positive practice and joint working between the police and other organisations to address antisocial behaviour.

We drew on evidence from academic research, national guidance and findings from:

• our police effectiveness, efficiency and legitimacy (PEEL) programme;

• force management statements (self-assessments that chief constables and their London equivalents prepare and give to us each year);

• a request for promising practice to all forces by the College of Policing; and publicly available data.

If and how policing affects crime has long been studied. On the relationship between police force size and crime, different authors come to different conclusions. This study examines the relationship between police resourcing, including workforce size, structure and stability over time using data for 42 police forces in the UK over a 13-year period.

We construct two novel panel datasets. The first comprises measures of police workforce Size, Structure and Stability. The second provides measures of both crime frequency and crime severity. Issues of endogeneity make the modelling of the police-crime association complicated. Consequently, we analyse the data using a panel vector autoregression (PVAR) model which is capable of forecasting a temporal sequence of the interdependencies between police-crime relationships.

Changes in total police personnel play an important role in reducing both crime frequency and severity, but the findings are more nuanced than this. Results highlight that the structure and stability of police organisations are important although these impacts are not always the same for crime volume and crime severity. We find that increases in frontline (non-sworn) support staff are associated with reductions in crime, while turnover rates of police staff are associated with increases in crime. In contrast, changes to the number of sworn police officers do not appear to be a good predictor of crime volume.

The findings suggest that investment in frontline support staff and the development of strategies to retain skills and knowledge by reducing staff turnover may be efficient approaches for Police Forces to maximise the impact on crime of their workforce in resource-pressed policing settings. While previous research has found that police force size has a limited effect on crime, our findings indicate that more nuanced measurements of police resourcing are necessary to understand how police impact upon crime risk. The idea of police forces using basic officer-to-population ratios to make staffing decisions appears outdated and over-simplistic.

Situational crime prevention (SCP) is an environmental crime control perspective with enormous practical and policy relevance due to its practitioner-friendly theoretical approach. This study examines whether SCP interventions reduce incident casualty outcomes in active shooter incidents. We used an inductive, open-source data set of 555 active shooter and mass public shooting sites to study the applicability of SCP to active shooter and mass public violence. Our findings suggest a harm mitigation role for SCP: active shooter sites with stronger holistic SCP had fewer casualties. We assessed perpetrator motivation to test displacement, a core critique of SCP, and found that the harm mitigation potential of SCP persists even in the presence of a highly motivated offender.

Policy summary

SCP could be a practical and effective method to decrease casualties in the event of an active shooting, which is a highly motivated crime type that is difficult to predict and prevent. Public locations may select a range of appropriate SCP techniques based on individual resources and needs. The totality and interactions of these techniques may contribute to public safety in general, with diffuse benefits. This policy solution is highly oriented toward practice and real-life application, and may be used to supplement existing preventative measures like threat assessment and gun legislation.

Preventing targeted violence in America is everyone's responsibility. Far too often, communities have witnessed mass injury and loss of life at the hands of an attacker, only to learn that the perpetrator had a long history of threatening or concerning behaviors. In many cases, the attacker's behavior was witnessed by community bystanders, some of whom sought to report their concerns to public safety officials. Unfortunately, many communities lack the structured systems to receive, evaluate, and respond to these reports in a way that reduces the likelihood of a violent outcome. The framework presented herein is the latest NTAC [National Threat Assessment Center] offering intended to support the violence prevention efforts of state and local law enforcement agencies. The steps that follow describe how agencies can adopt the principles of the Secret Service model to proactively identify and intervene with those who intend to carry out acts of targeted violence in their communities. These steps are not intended to be prescriptive, but rather offer a scalable blueprint that can be implemented by agencies varying in size, structure, and resources, all of which share the Secret Service's mission of preventing targeted violence.

Traditional police response to crime has been reactive, yet nationwide trends toward problem-oriented and community-oriented policing have changed this approach in many departments. Over the past decade, police executives have shifted to more proactive policing and have instituted collaborative programs with a wide range of community groups and other organizations to prevent crime. These programs likely have contributed to decreasing rime, with most success demonstrated by the vast reduction in the nation’s homicide rate.

This report reviews current trends in homicide rates, the changing police perspective on homicide prevention, and summarizes innovative police department programs as captured in a Bureau of Justice Assistance (BJA) and Police Executive Research Forum (PERF) exploratory project that examined the homicide prevention practices of over 70 police departments. The goal of this report is to highlight successful policing strategies and programs offered by departments in cities that have reduced homicide. Descriptions of homicide prevention strategies and key program elements common to successful police departments around the country may serve as a guide to other police executives seeking to reduce homicide in their communities.

The serious nature of intimate partner violence and the harm to women and their children has been acknowledged in numerous documents (Statistics Canada, 2005; Tutty & Goard, 2002). The costs to society for charging abusive partners and providing treatment in the hope of stopping domestic violence are substantial (Bowlus, McKenna, Day & Wright, 2003; Greaves, Hankivsky, & Kingston-Reichers, 1995; Healey, Smith, & O‘Sullivan, 1998).

The criminal justice system is an institution that deals with a high number of cases of domestic assaults yearly. While there is no separate domestic violence offence, abusers are subject to a variety of charges, from common assault to uttering threats to murder, that would apply to anyone regardless of the relationship between the victim and the perpetrator. Nevertheless, the dynamics and the intimate relationship between the accused and the victims in domestic violence cases, has severely challenged the criminal justice response that typically deals with crimes committed by strangers.

Beginning with the development of the court in Winnipeg in 1991, specialized domestic violence courts have become increasingly available across Canada with the goal of more effectively addressing the criminal justice response to domestic violence. The extensive effort involved in creating such specialized justice responses should be acknowledged. To date, however, few evaluations have been published that assess whether these initiatives make a difference, exceptions being the work of Ursel in Winnipeg, the Yukon Domestic Violence Treatment Option (Hornick, Boyes, Tutty & White, 2005: funded by NCPC), some courts in Ontario (Moyer, Rettinger & Hotton (2000), cited in Clarke, 2003; Dawson & Dinovitzer, 2001), and Tutty and Ursel in the Canadian prairie provinces (Ursel, Tutty, & LeMaistre, 2008).

Calgary‘s model developed in early 2000 with the input of key players from not only the criminal justice institutions such as police services, the Crown Prosecutor offices, probation, Legal Aid and the defence bar, but also community agencies that offer batterer intervention programs and support, shelter and advocacy for victims. The model was innovative, with the initial emphasis on a specialized domestic violence docket court with the aim of speeding up the process for those charges with domestic abuse offences to both allow low risk offenders to take responsibility for their actions and speed their entry into treatment.

Such actions were thought to better safeguard victims, both because their partners were mandated to treatment much earlier, and to prevent repercussions to victims who, if the case proceeded to court, might be required to testify. Crisis intervention theory has long posited that the sooner one receives intervention, the more likely the counselling will be effective (Roberts & Everly, 2006). Also, the safety and wishes of the victims are taken into consideration by the court team early on in the process, while the assault is still fresh in their minds and they are not influenced by the accused to the same extent as they might be later on.

The problem of policing is often portrayed as providing sufficient personnel to sate demand. Pluralism, however, complicates the issue since the public disagree among themselves over which activities or individuals should be policed. In turn, police priorities may differ from these demands, inciting public discontent. In these circumstances, how can public policing sustain its legitimacy? Lessons can be learnt from how political theories have grappled with pluralism and legitimacy. This article analyses how three major political theorists, John Rawls, Michael Walzer and Friedrich Hayek, dealt with these issues. It mines their insights to nominate the principle of non- domination, defined as freedom from interference on an arbitrary basis, as best suited to justify policing in an era of pluralism.

Background: Hot spots policing is one of the most influential police innovations, with a strong body of experimental research showing it to be effective in reducing crime and disorder. However, most studies have been conducted in major cities, and we thus know little about whether it is effective in smaller cities that account for a majority of police agencies. The lack of experimental studies in smaller cities is likely partly due to challenges of designing statistically powerful tests in such contexts.

Objectives: The current paper explores the challenges of statistical power and “noise” resulting from low base rates of crime in smaller cities and provides suggestions for future evaluations to overcome these limitations.

Research Design: Crime data from a randomized, experimental evaluation of broken windows policing in hot spots are used to illustrate the challenges that low base rates present for evaluating hot spots police innovations in smaller cities.

Results: Analyses show that low base rates make it difficult to detect treatment effects. Very large effect sizes would be required to reach sufficient power, and random fluctuations around low base rates make detecting treatment effects difficult irrespective of power by masking differences between treatment and control groups.

Conclusions: Low base rates present strong challenges to researchers attempting to evaluate hot spots policing in smaller cities. As such, base rates must be taken directly into account when designing experimental evaluations. The paper offers suggestions to researchers who attempt to expand the examination of hot spots policing and other microplace-based interventions to smaller jurisdictions.

Problem-oriented policing was first introduced in an article by Herman Goldstein in 1979. It was formally field-tested in the 1980s in Baltimore County (Cordner, 1986) and Newport News (Eck and Spelman, 1987), given a wider audience through an Atlantic Monthly magazine article in 1989 (Wilson and Kelling), and systematically described and explained in Goldstein's 1990 book. Today, it is widely regarded as the most analytical and intellectually challenging strategy in the police arsenal.

Questions linger, however, about the implementation and practicality of problem-oriented policing (POP). The SARA process (scanning, analysis, response, assessment) for carrying out POP is analytically and creatively demanding, as well as time-consuming. Some observers question whether police have the knowledge and skill to implement the SARA process properly. Police officers often question whether they have the time to do so.

The research reported here carefully examined problem-oriented policing in practice by ordinary police officers in one agency - the San Diego, California Police Department. The objective was to discover and describe the reality of everyday, street-level POP as practiced by generalist patrol officers. San Diego was chosen because of its reputation as a national leader in problem-oriented policing.

This paper discusses some of the difficulties encountered in attempting to introduce ideas derived from research on repeat victimization to the police services of the United Kingdom. Repeat victimization is the phenomenon in which particular individuals or other targets are repeatedly attacked or subjected to other forms of victimization, including the loss of property. It is argued that repeat victimization is a good example of the kind of problem solving envisaged by Goldstein and discussed in his original conception of problem-oriented policing.

This article asks if investigative police stops (1) help officers find contraband, and (2) serve as a bulwark against violent crime. We focus on the experiences of Fayetteville, North Carolina, which in 2012 mandated that police officers obtain written permission from motorists before conducting searches absent any probable cause. The effect of these mandates was a dramatic reduction in the use of so-called “consent searches.” Using traffic stops data available from the North Carolina Department of Justice, we show that after these reforms went into effect officers made fewer overall searches, but contraband continued to be recovered at pre-reform levels, indicating a reduction in low-quality searches with minimal substantive impact. Moreover, we find that homicide rates are statistically indistinguishable between the pre- and postreform periods. Thus, Fayetteville local government was able to implement community pleasing police reforms without jeopardizing community safety.

We evaluate the factors associated with an officer’s decision to search a driver or vehicle after a routine traffic stop, and we compare the accuracy of these searches by looking at the share leading to arrest. Racial disparities in search rates by race and gender of driver are similar for all types of officers; all tend to search Black male drivers at higher rates than any other demographic. White male officers have higher search rates for all types of drivers. Further, they conduct the greatest share of “fruitless searches” (those not leading to arrest), and these searches are particularly targeted on those drivers with the greatest number of cumulative disadvantages

Substantial evidence suggests that focussing police resources on hotspots of crime has a discernable crime-re duction effect. However, little is known about the efficacy of proactively policing areas with higher concentrations of more common low-harm problems in society. This study evaluates the first national double-blind randomized controlled trial in which clearly identifiable hotspots (n = 488) of low-harm ‘quality-of-life’ incidents nested in 31 participating police stations were randomized to be either actively policed by any available police officer or by ‘business-as-usual’ reactive policing over a 12-month period. A series of count-based regression models show a moderate and statistically significant reduction in the number of quality-of-life incidents in treatment versus control hotspots, with more than 2,000 quality-of-life incidents prevented, without evidence of spatial displacement to street segments nearby. However, we find no diffusion of benefits in terms of other crime types within the same hotspots, which may suggest that either low- and high-harm crime hotspots are not spatially aligned with each other, that focusing police officers on one type of crime does not produce a suppression effect on other types of crime, or both. We discuss the implications of these results for crime policy and future research.

We systematically review the effectiveness of police presence. In doing so, we investigate concepts of police presence and differences between reported effects. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and protocols, we systematically identify and review eligible studies on police presence. Further, quality assessment and findings synthesis are used to map limitations of current research as well as grounds for future avenues. The systematic search strategies yielded 49 studies focusing on testing the effects of police presence or evaluating its measurement. We find evidence that police presence has mostly crime reduction effects on crimes related to motor theft, property, violence, and guns. Police presence also reduces calls for service and improves traffic behaviour. Police presence focused on specific areas, times, and types of crime achieves maximum effectiveness. The reviewed studies show a high degree of heterogeneity in reporting, however, which limits comparability of findings across studies. Research on police presence presents evidence for significant crime preventative effects of focused police actions. Police presence shows the strongest effects when focused on certain areas, times, or types of crimes. We encourage future research to focus on police presence en route and its effects, including crime prevention, traffic regulation, and fear of crime.

We have entered a new era of increasingly disruptive protests. This report shows how decisions made by the police, prosecutors, courts, Parliament and Government mean that undue weight is being placed on the rights and interests of disruptive (and, at times, criminal) activists at the expense of the rights, wellbeing and interests of ordinary members of the public.

This report addresses two central questions:

• Do the police, and other authorities, use their existing powers effectively to deal with disruptive protest?

• Is the existing legal regime fit for purpose?

The answer to both questions, as we show in this report, is no.

As the new Government will soon commence their review of the legislation relating to protest and the Home Office continues their appeal in a high-profile protest-related court case this report is highly relevant to the contemporary policy making and legal context.

The report argues that the new Government must prioritise the rights, wellbeing and interests of ordinary members of the public – otherwise they risk finding themselves in the same difficulties as their predecessors.

In addition to a detailed analysis of the police approach to protest, this report also contains recent polling on the public mood and a detailed review of the current legal regime. The report has 26 recommendations for Government, police forces, the Crown Prosecution Service and the Mayor of London.

Sanctioned by the courts and taught in police manuals, deceptive tactics are employed by virtually every police department across the country. Officers seeking to elicit a confession will routinely lie to suspects about the evidence and make statements that imply leniency. While effective at times, deception is ethically dubious and can result in severe consequences for suspects. The United States is an outlier in allowing police to deceive suspects, as the practice is prohibited or highly restricted in most peer nations, including England, France, Germany, and Japan. First, deceptive interrogation tactics frequently induce false confessions, which are a leading cause of wrongful convictions in the United States. Further, the acceptability of lying to suspects during interrogations seems to encourage deception in other, more troubling contexts. Research shows that testimonial lies, such as perjury in court and falsifying police reports, are commonly employed by officers to secure convictions and circumvent constitutional protections. While such practices remain illegal, testimonial lies are rarely identified or punished. As a result, the justifications and skills cultivated through deceiving suspects in interrogations naturally bleed over into other police work. Ultimately, the pervasiveness of police deception undermines the integrity and legitimacy of the criminal justice system. It leads to wrongful convictions, weakens civil liberties, and erodes public trust in law enforcement. While there are difficult trade-offs in regulating police deception, its negative consequences require policy responses. Contrary to contentions that deceit is a necessary tool of law enforcement, experiences in other nations suggest that restricting police deception does not hamper criminal investigations. Policymakers should consider measures to curtail police deception, such as requiring that interrogations be recorded, banning or limiting certain deceptive tactics, and increasing judicial scrutiny of interrogation practices
