Deaths of civilians at the hands of on-duty police are in the national spotlight as never before. How many killings by police occur annually? What circumstances provoke police to shoot to kill? Who dies? The lack of answers to these basic questions points to a crisis in American government that urgently requires the attention of policy experts. When Police Kill is a groundbreaking analysis of the use of lethal force by police in the United States and how its death toll can be reduced.

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.

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.

In this illuminating history that spans past campaigns against piracy and slavery to contemporary campaigns against drug trafficking and transnational terrorism, Peter Andreas and Ethan Nadelmann explain how and why prohibitions and policing practices increasingly extend across borders. The internationalization of crime control is too often described as simply a natural and predictable response to the growth of transnational crime in an age of globalization. Andreas and Nadelmann challenge this conventional view as at best incomplete and at worst misleading. The internationalization of policing, they demonstrate, primarily reflects ambitious efforts by generations of western powers to export their own definitions of "crime," not just for political and economic gain but also in an attempt to promote their own morals to other parts of the world.

A thought-provoking analysis of the historical expansion and recent dramatic acceleration of international crime control, Policing the Globe provides a much-needed bridge between criminal justice and international relations on a topic of crucial public importance.

In this report, RAND Corporation researchers summarize what is currently known about killings committed by police officers in the United States and identify existing evidence about various ways to prevent these killings. A relatively large body of research on these topics exists, but these studies often suffer from methodological shortcomings, largely stemming from the dearth of available data. Recognizing the need for more-rigorous work to guide efforts to reform police — and, more specifically, to reduce police killings — the authors present work focused on the development of a research agenda, or a road map, to reduce police killings. The report, based on an extensive literature review as well as interviews with policing experts, contains a series of recommendations for areas in which research efforts may be most effective in helping inform policy-making and decision-making aimed at reducing police killings.

The authors identified six focus areas — foundational issues (such as racial inequities, police culture, and police unions), data and reporting, training, policies, technology, and consequences for officers. Reviewing the priority research topics in each focus area, similar themes emerged, especially around the need for more-extensive and more-systematic data collection and around the use of agency policies to better govern a range of operations related to police violence, such as data collection and reporting and technology.

  In this report, the authors use the terms police killings, police violence, and police shootings to describe these types of police behaviors, whether wrongful or not. The authors identify specific instances of these behaviors as misconduct, illegality, wrongful, or excessive when those descriptions apply.

Congress enacted the Death in Custody Reporting Act of 2013 (DCRA) to address the lack of reliable information about law enforcement–related deaths and deaths in correctional institutions. The U.S. Department of Justice has conducted several activities designed to respond to the provisions specified in the DCRA legislation, as well as their own federal mandates, toward a comprehensive understanding of the prevalence and characteristics of deaths that occur in law enforcement custody. Despite these efforts, no national data collection program currently describes all deaths that occur in law enforcement custody. These data are critical to support strategies to reduce such deaths; to promote public safety through appropriate responses to reported crimes, calls for service, and police-community encounters; and to build trust with communities.

  To better understand the needs around developing and leveraging data from a national data collection of law enforcement–related deaths, RTI International and the RAND Corporation, on behalf of the National Institute of Justice, convened a panel of experts to discuss the challenges to conducting a national data collection, to recommend potential solutions to those challenges, and to recommend research and other applications for the collected data. Through a three-session virtual workshop, participants identified 19 high-priority needs to support a comprehensive and robust data collection program on law enforcement–related deaths. These high-priority needs address challenges related to scope, definition, and detail of the collection; data collection elements and reporting needs; and the utility of the information to inform law enforcement training, programs, and policies.

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.

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.

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.

The National Institute of Justice tasked RAND to host a panel of law enforcement experts to identify high-priority needs for innovation in law enforcement, covering advances in technology, policy, and practice. The needs discussed in this report can help prioritize research, development, and dissemination efforts in ways that will provide the greatest value to law enforcement practitioners.

The panel identified four top findings. First, there is a need to improve practitioners' knowledge of available research and technology, starting with a central knowledge repository and research on how to improve dissemination and training methods. Second, there is a need for practices and technologies to improve police-community relations, both to improve encounters with the public and to improve community relations more broadly. Third, there is a need to improve the sharing and use of information in a range of ways. These include means to get crime analysis capabilities to all agencies (including small and disadvantaged agencies), software development to reduce information overload, and model proposal and contract language to make systems interoperable. Fourth, there is a need to reduce backlogs in forensic processing; panelists suggested broadening U.S. Department of Justice forensic grants outside of DNA to help address the backlogs.

Additional high-priority needs included further development of policies and use cases for unmanned aerial vehicles, best practices for selecting and using personal gear, and improving defenses against active shooters. The latter included improving both suspicious activity reporting processes and efforts to educate the public on responding to an active shooter. There is also a need for a review of technologies that might improve officers' health.

When police brutality becomes front-page news, it triggers a sudden, intense interaction between the media, the public, and the police. Regina Lawrence ably demonstrates how these news events provide the raw materials for looking at underlying problems in American society. Journalists, policy makers, and the public use such stories to define a problematic situation, and this process of problem definition gives the media a crucial role in our public policy debates.

Lawrence extensively analyzes more than 500 incidents of police use-of-force covered by the New York Times and the Los Angeles Times from 1985 to 1994, with additional analysis of more recent incidents such as as the shooting of Amadou Diallo in New York. The incidents include but are not limited to those defined as "police brutality." Lawrence reveals the structural and cultural forces that both shape the news and allow police to define most use-of-force incidents, which occur in far greater numbers than are reported, she says.

• More.....

  Lawrence explores the dilemma of obtaining critical media perspectives on policing policies. She examines the factors that made the coverage of the Rodney King beating so significant, particularly after the incident was captured on video. At the same time, she shows how an extraordinary news event involving the police can become a vehicle for marginalized social groups to gain entrance into the media arena.

  In contrasting "event-driven" problem definition with the more thoroughly studied "institutionally driven" news stories, Lawrence's book fills a major gap in media studies. It also offers a broader understanding of the interplay between the criminal justice system and the media in today's world.Description text goes here

How do high-profile acts of police brutality affect public trust and cooperation with law enforcement? To investigate this question, we develop a new measure of civilian crime reporting that isolates changes in community engagement with police from underlying changes in crime: the ratio of police-related 911 calls to gunshots detected by ShotSpotter technology. Examining detailed data from eight major American cities, we show a sharp drop in both the call-to-shot ratio and 911 call volume immediately after the police murder of George Floyd in May 2020. Notably, reporting rates decreased significantly in both non-white and white neighborhoods across the country. These effects persist for several months, and we find little evidence that they were reversed by the conviction of Floyd’s murderer. Together, the results illustrate how acts of police violence may destroy a key input into effective law enforcement and public safety: civilian engagement and reporting.

This report examines the outcomes of the consent decree between the Civil Rights Division of the United States Department of Justice and the Pittsburgh Police Bureau.

In 1994, the United States Congress expanded the powers of the Civil Rights Division of the Justice Department by granting it the authority to file civil lawsuits against States and municipalities that display a "pattern or practice" of police misconduct. The department has filed six lawsuits, all of which have been settled out of court through consent decrees. These decrees specify the reforms the police agencies must implement; the first consent decree was negotiated in Pittsburgh, PA. Researchers at the Vera Institute of Justice questioned whether the use of this new Federal intervention power could make a sustainable difference in the operation of local law enforcement agencies.

• More.....

  Researchers studied the Pittsburgh Police Bureau both before and after the consent decree was lifted in 2002. Research methods involved observations of police in field and management settings, interviews with key officials and community leaders, focus groups with police officers, surveys of citizens, and reviews of the Federal monitor's reports and police data. Findings indicated two key factors were most responsible for the quick compliance with the terms of the decree: the leadership displayed by the police chief and guidance received from the Federal monitor. Several changes were made to the way the police agency operated, including the addition of new systems to track the use of force, traffic stops, and searches, as well as new procedures to increase officer accountability and new policies and training. Despite budget cutbacks, these new reforms remain in place and the surveys of community leaders and citizens indicate significant improvements in police services. Problems remain however, as front-line police officers complain about tighter management and citizens continue to voice concerns about police misconduct. The overall findings suggest that this type of Federal intervention can bring lasting improvements in police accountability. Description text goes here

Do collective bargaining rights for law enforcement result in more civilian deaths at the hands of the police? Using an event-study design, we find that the introduction of duty to bargain requirements with police unions has led to a significant increase in non-white civilian deaths at the hands of police during the late twentieth century. We find no impact on various crime rate measures and suggestive evidence of a decline in police employment, consistent with increasing compensation. Our results indicate that the adoption of collective bargaining rights for law enforcement can explain approximately 10 percent of the total non-white civilian deaths at the hands of law enforcement between 1959 and 1988. This effect is robust to a contiguous county approach, accounting for heterogeneity in treatment timing, and numerous other specifications. While the relationship between police unions and violence against civilians is not clear ex-ante, our results show that the popular notion that police unions exacerbate police violence is empirically grounded.

This paper provides the first empirical examination of the impact of federal and state "Pattern-or-Practice" investigations on crime and policing. For investigations that were not preceded by "viral" incidents of deadly force, investigations, on average, led to a statistically significant reduction in homicides and total crime. In stark contrast, all investigations that were preceded by "viral" incidents of deadly force have led to a large and statistically significant increase in homicides and total crime. We estimate that these investigations caused almost 900 excess homicides and almost 34,000 excess felonies. The leading hypothesis for why these investigations increase homicides and total crime is an abrupt change in the quantity of policing activity. In Chicago, the number of police-civilian interactions decreased by almost 90% in the month after the investigation was announced. In Riverside CA, interactions decreased 54%. In St. Louis, self-initiated police activities declined by 46%. Other theories we test such as changes in community trust or the aggressiveness of consent decrees associated with investigations -- all contradict the data in important ways.

As a new Commissioner of the Metropolitan Police is appointed, Policy Exchange has published our report, “‘Policing Can Win’: The New Commissioner’s First 100 Days” by David Spencer, Policy Exchange’s Head of Crime & Justice.

The central thesis to this report is that ‘Policing Can Win’ over those who would commit crime and disorder in our communities. In addition to summarising the core issues the Met has faced over the last five years, this report sets out the three areas where substantial changes must be made:

Leadership at Every Level: Providing the leadership that the officers and staff of the Met need to effectively fight crime and keep the public safe. Fighting Crime and Reconnecting with the Public: Reigniting the tradition that only by working closely with the public will the police be successful in retaining the public’s confidence, fighting crime and disorder, and keeping the public safe. Police Officer Conduct and Competence:Eliminating from policing those who are incompetent or would break the public’s trust in policing by committing criminality or misconduct.

Though recognition of the importance and severity of human trafficking has grown in recent years, the identification and investigation of human trafficking cases remains a complex undertaking for local law enforcement. Effectively responding to human trafficking requires officers to notice and identify victims who often have been hidden from or had poor relationships with law enforcement in the past (e.g., women in prostitution, migrants, immigrant community member, and poor women). Sometimes officers may be reluctant to intervene in sex and labor trafficking situations due to a belief that victims were complicit with their own victimization. Local law enforcement response is further complicated by immigration issues since many local agencies have made a decision to not inquire about citizen status during routine policing activities as a means of building trust and confidence in the local community. Additionally, the crime of human trafficking may take backseat to other institutional priorities such as violence and drugs. Finally, officers must look at old problems or traditional crime categories such as prostitution through a different lens and therefore reclassify "offenders" such as prostitutes as victims.

  Since the enforcement of the law in the United States is predominately carried out by the thousands of local, county and state agencies representing diverse environments and local crime problems and coming from a variety of different organizational structures, fully understanding how law enforcement perceives and responds to the problem of human trafficking in the United States necessitates inquiry into the specific experiences of these agencies. The majority of research on law enforcement responses to human trafficking to date has focused on the experiences of a narrow number of large municipal police departments who were perceived to be most likely to come into contact with incidents of human trafficking. In response, this project addresses four main areas: 1) the perceptions of trafficking held by law enf rcement and the preparation agencies have taken to address the problem, 2) the frequency in which law enforcement identifies and investigates cases of human trafficking and 3) the characteristics of those cases investigated by law enforcement and 4) the investigation and prosecution of human trafficking cases.

Stark racial inequity has long been a deeply troubling aspect of our criminal justice system. In recent years, traffic stops have emerged as a key factor driving some of these inequities and an area of potential reform. Are there opportunities to identify kinds of traffic stops that could be enforced in alternative ways—potentially improving officer and civilian safety, enhancing police efficiency, and reducing racial disparities—without jeopardizing road safety?

To explore this question, in this report we use data on 3.4 million traffic stops made in 2019 by California’s 15 largest law enforcement agencies to examine racial disparities in stop outcomes and experiences across time of the day, type of law enforcement agency, and type of traffic violation.

Suspect Citizens offers the most comprehensive look to date at the most common form of police-citizen interactions, the routine traffic stop. Throughout the war on crime, police agencies have used traffic stops to search drivers suspected of carrying contraband. From the beginning, police agencies made it clear that very large numbers of police stops would have to occur before an officer might interdict a significant drug shipment. Unstated in that calculation was that many Americans would be subjected to police investigations so that a small number of high-level offenders might be found. The key element in this strategy, which kept it hidden from widespread public scrutiny, was that middle-class white Americans were largely exempt from its consequences. Tracking these police practices down to the officer level, Suspect Citizens documents the extreme rarity of drug busts and reveals sustained and troubling disparities in how racial groups are treated.
