Is the Chicago Consent Decree Working? Consent Decrees for Police Reform: The Chicago Experience

By Charles Fain Lehman

In 2019, the Chicago Police Department (CPD)—one of the most controversial police departments in the nation—was placed under a federally enforced consent decree that mandates sweeping reforms and subjects the department to the supervision of a court-appointed independent monitor. Although implementation of the decree is still ongoing, this report reviews the preliminary evidence of its effects. Across a variety of indicators, it seems that the consent decree has not had an appreciable effect on police conduct or public perception of the department. And there is at least some evidence that the process leading up to the consent decree exacerbated Chicago’s already-substantial crime problem. While prior research on consent decrees suggests that they can sometimes have an effect, that outcome is far from certain, casting further doubt on the prospects of Chicago’s decree. Why is the consent decree having little or no measurable impact? It may be the result of unwillingness on the part of CPD and the city to embrace reform. Alternatively, the consent decree’s ineffectiveness may be attributed to preexisting reforms that CPD had already implemented on its own before the decree took effect. Both of these explanations, however, cast doubt on the viability of the federal investigation and consent decree process as a tool for achieving police reform.

Examining the effects of the killing of George Floyd by police in the United States on attitudes of Black Londoners: a replication

By Amy Nivette,Christof Nägel &Emily Gilbert

High-profile incidents of police misconduct can have serious conse-quences for public trust in the police. A recent study in the British Journal of Political Science found that Eric Garner’s death in NYC led to more negative attitudes towards the police in London among Black residents compared to White and Asian residents. The current study aimed to replicate this transnational effect by assessing the impact of George Floyd’s death on Londoners’ perceptions of police. Using the same data and methodological approach, we did not replicate the immediate effect on Black Londoners’ attitudes. We did find that attitudes across ethnic groups became more negative when using a wider temporal bandwidth. However, we discovered violations to the excludability assumption, meaning we cannot be certain that the effect is solely due to the murder of George Floyd, or at least partly due to different dynamics, like the effects of the COVID-19 pandemic and the accompanying policies. This means that while it is possible that police killings in other contexts play a role in shaping attitudes towards local police, these effects are difficult to disentangle from other global and local factors. misconduct can reduce trust and confidence in the police among the wider public (Kochel, 2019; Nägel & Lutter, 2021; Reny & Newman, 2021).

Exceptionally Lethal: American Police Killings in a Comparative Perspective

By Paul J. Hirschfield

Police in the United States stand out in the developed world for their reliance on deadly force. Other nations in the Americas, however, feature higher or similar levels of fatal police violence (FPV). Cross-national comparative analyses can help identify stable and malleable factors that distinguish high-FPV from low-FPV countries. Two factors that clearly stand out among high-FPV nations are elevated rates of gun violence—which fosters a preoccupation with danger and wide latitude to use preemptive force—and ethnoracial inequality and discord. The latter seems to be tied to another fundamental difference between the United States and most other developed nations—the “radically decentralized structure of U.S. policing” (Bayley & Stenning 2016). Hyperlocalism limits the influence of external oversight, along with expertise and resources for effective training, policy implementation, and accountability. However, elevated rates of FPV among some Latin American countries with relatively centralized policing demonstrate that decentralization is not a necessary condition for high FPV. Likewise, relatively low FPV in Spain and Chile suggests that achieving low FPV is also possible without the extensive resources and training that appear to suppress FPV in wealthy Northern European nations.

Race, Place, and Effective Policing

By Anthony A. Braga, Rod K. Brunson, and Kevin M. Drakulich

The police need public support and cooperation to be effective in controlling crime and holding offenders accountable. In many disadvantaged communities of color, poor relationships between the police and residents undermine effective policing. Weak police–minority community relationships are rooted in a long history of discriminatory practices and contemporary proactive policing strategies that are overly aggressive and associated with racial disparities. There are no simple solutions to address the complex rift between the police and the minority communities that they serve. The available evidence suggests that there are policies and practices that could improve police–minority community relations and enhance police effectiveness. Police departments should conduct more sophisticated analysis of crime problems to ensure that crime-control programs are not indiscriminate and unfocused, engage residents in their crime reduction efforts by revitalizing community policing, ensure procedurally just police contacts with citizens, and implement problem-solving strategies to prevent crimes beyond surveillance and enforcement actions.

Disorder policing to reduce crime: A systematic review

By Anthony A. Braga, Brandon C. Welsh, Cory Schnell

Disorderly conditions are seen as a precursor to more serious crime, fear of crime, and neighborhood decline. Policing disorder is associated with reductions in crime, but only when community and problem-solving tactics are used. Aggressive, order maintenance based approaches do not seem to be effective.

What is this review about?

Policing social and physical disorderly conditions is rooted in the broken windows approach: disorder is a precursor to more serious crime, fear of crime, and neighborhood decline. Addressing disorder has become a central fixture of policing, especially in the United States. Yet, evaluations of the effectiveness of disorder policing strategies in controlling crime yield conflicting results.

Policing disorderly conditions can be divided into two main strategies: (a) order maintenance or zero tolerance policing, where police attempt to impose order through strict enforcement and (b) community policing and problem-solving policing, where police attempt to produce order and reduce crime through cooperation with community members and by addressing specific recurring problems.

This review examined the effects of disorder policing strategies compared to traditional law enforcement actions (e.g., regular levels of patrol) on the rates of crime, including property crime, violent crime, and disorder/drug crime. This review also examined whether policing disorder actions at specific locations result in crime displacement (i.e., crime moving around the corner) or diffusion of crime control benefits (i.e., crime reduction in surrounding areas).

Improving Police Clearance Rates of Shootings: A Review of the Evidence

By Anthony A. Braga

Clearance rates for fatal and nonfatal shootings, especially cases involving gang- and drug-related violence, are disturbingly low in many American cities. Low clearance rates undermine police efforts to hold offenders accountable, to disrupt cycles of gun violence, and to provide justice to victims. The prevailing view has been that follow-up investigations are of limited value because crimes are primarily cleared by patrol officers making on-scene arrests and through eyewitnesses and forensic evidence at the crime scene. Other research, however, suggests that the work of criminal investigators can increase the likelihood that crimes might be cleared through arrest. After years of homicide clearance rates that were lower than the national average, the Boston Police Department engaged a research and development enterprise to improve their posthomicide criminal-investigation processes and practices. A rigorous evaluation found that the intervention significantly increased key investigative activities and improved clearance rates relative to existing homicide clearance trends in other Massachusetts and U.S. jurisdictions. This research enterprise was extended to compare city investigative resources invested in clearing gun-homicide cases relative to nonfatal gun assaults. The study found that gun homicides and nonfatal shooting cases shared very similar characteristics. However, higher clearance rates for gun homicides relative to nonfatal shootings were primarily a result of sustained investigative effort in homicide cases made following the first two days. Police departments should invest additional resources in the investigation of nonfatal gun assaults. When additional investigative effort is expended, law enforcement improves its success in gaining the cooperation of key witnesses and increases the amount of forensic evidence collected and analyzed.

Law Enforcement Training and the Domestic Far Right

By Steven M. Chermak, Joshua D. Freilich and Zachary Shemtob

This article examines issues related to training as it pertains to domestic terrorism in general and responding to far-right extremists in particular. First, it hightlights current training practices and training focused on the far right. Second, it details knowledge about the nature and extent of the threat posed by far-right extremists. Third, a review of the empirical research indicates that training could be enhanced if three key issues are emphasized: Future training should promote a better understanding of the contours of the far right; discuss the unique geographic, crime-incident, and structural characteristics of the far right; and describe the need to examine all ideologically motivated crimes, regardless of whether they are also defined as terrorist. The conclusion discusses how training could be enhanced by strategically integrating the existing knowledge base.

Microtargeting Unmasked: Safeguarding Law Enforcement, the Military, and the Nation in the Era of Personalized Threats

By Lindsay, Greg; Brown, Jason C.; Johnson, Brian David; Owens, Christopher; Hall, Andrew; Carrott, James H.

From the document: "Microtargeting is the practice of collecting and analyzing personal data to create highly specific messaging for advertising, marketing, and influence campaigns. With microtargeting, the adversary's goal is to destabilize the leadership and decisionmaking of federal institutions tasked with protecting the population. This report describes how, in the coming decade, state and non-state adversaries will use microtargeting tactics to attack high-value individuals (HVIs) in military, law enforcement, and civilian leadership to stigmatize, extort, and even assassinate figures crucial to the security and stability of the United States. Adversaries will also use microtargeting tactics to manipulate and exploit individuals in proximity to HVIs when the HVI is unreachable (e.g., physical proximity, familial ties, business associates, and/or friends)."

Regulating US Private Security Contractors

USED BOOK. MAY CONTAIN MARK-UP

By Jovana Jezdimirovic Ranito

FROM THE INTRODUCTION: “…September 16, 2007, Nisour Square in Baghdad, Iraq: Blackwater contractors, working under a State Department contract, kill 17 civilians and injure 20 during a firefight. Fast forward to September 11, 2009, Washington, DC: a Court of Appeals dismisses the charges against contractors and claims they were under US government contractor immunity. More recently, in 2014, after a number of appeals regarding the Court of Appeals and Supreme Court's decision about Abu Ghraib, which ended with a dismissal of charges, detainees filed a suit against contractors again, but still without a favorable outcome. Also, in 2015, in Washington, DC, four of the Blackwater contractors involved in the Nisour Square Massacre received a sentence from a federal judge after years of dismissals and new trials. These lengthy sentences were thrown out on August 4, 2017, by Federal Appeals Court and it ordered a new trial.

These examples are just the most reported ones, but they illustrate well the state of the US regulation regarding private security contractors operating in combat zones overseas…”

Into the Kill Zone: A Cop's Eye View of Deadly Force

By David Klinger

What's it like to have official sanction to shoot and kill? In this brilliantly written, controversial, and compelling book, author David Klinger - who himself shot and killed a suspect during his first year as an officer in the Los Angeles Police Department - answers this and many other questions about what it's like to live and work in the place where police officers have to make split-second decisions about life and death: The Kill Zone.

Klinger, now a university professor, writes eloquently about what happens when police officers find themselves face-to-face with dangerous criminals, the excruciating decisions they have to make to shoot or to hold their fire, and how they deal with the consequences of their choices.

2023 National Intelligence Strategy

By United States. Office Of The Director Of National Intelligence; Intelligence Community (U.S.)

From the document: "Following the attacks of September 11, 2001, and in the wake of the Intelligence Reform and Terrorism Prevention Act passed by Congress in 2004, Director of National Intelligence John D. Negroponte signed out the Intelligence Community's (IC) first National Intelligence Strategy. The strategy explained that the Intelligence Community's clear charge was to: [1] Integrate the domestic and foreign dimensions of U.S. intelligence so that there are no gaps in our understanding of threats to our national security; [2] Bring more depth and accuracy to intelligence analysis; and [3] Ensure that U.S. intelligence resources generate future capabilities as well as present results. Now, almost twenty years after our first strategy was issued, the Intelligence Community's charge remains just as clear, even as the strategic environment has changed dramatically. The United States faces an increasingly complex and interconnected threat environment characterized by strategic competition between the United States, the People's Republic of China (PRC), and the Russian Federation, felt perhaps most immediately in Russia's ongoing aggression in Ukraine. In addition to states, sub-national and non-state actors--from multinational corporations to transnational social movements--are increasingly able to create influence, compete for information, and secure or deny political and security outcomes, which provides opportunities for new partnerships as well as new challenges to U.S. interests. In addition, shared global challenges, including climate change, human and health security, as well as emerging and disruptive technological advances, are converging in ways that produce significant consequences that are often difficult to predict. [...] The six goals outlined in this National Intelligence Strategy have emerged as our understanding of the kinds of information, technology, and relationships needed to be effective in the future has expanded."

Perceptions Are Not Reality: What Americans Get Wrong About Police Violence

By Goldberg, Zach

From the document: "Recently, there has been a dramatic increase in media and public attention to police brutality and racial bias. By some measures, the volume of media references to these topics has been greater over the past decade than ever before. Google search behavior shows that Americans are consuming this messaging ('Figure 1'), and their attitudes toward police--particularly Democrats' and liberals' attitudes--have responded accordingly. Confidence in police has never been lower, while antipolice sentiment, perceptions of police brutality and racism, and support for defunding the police have never been higher. So much have perceptions of racist policing grown that, as of 2021, more than half (52%) of Democrats felt that levels of racism were greater among police officers than other societal groups (up from 35% in 2014). Fears of the police among black Americans have increased to the point that, in 2020, roughly 74% of black respondents to a Quinnipiac University poll said that they 'personally worry' about being the victim of police brutality, compared with 64% and 57% who said so in 2018 and 2016, respectively. Yet these trends in media coverage and public perceptions seem divorced from empirical reality. A stark illustration of this was provided by a nationally representative survey conducted in 2019 by the Skeptic Research Center, which found that nearly 33% of people--including 44% of liberals--thought that 1,000 or more unarmed black men 'alone' were killed by police in 2019. In fact, according to the Mapping Police Violence (MPV) database, 29 unarmed black (vs. 44 white) men were killed by police that year."

2023 Biodefense Posture Review

By United States. Department Of Defense

From the document: "The Department of Defense (DoD) is at a pivotal moment in biodefense as it faces an unprecedented number of complex biological threats (biothreats). This inaugural DoD Biodefense Posture Review (BPR) initiates key reforms--built on the foundations of the 2022 National Defense Strategy (NDS), the October 2022 National Biodefense Strategy and Implementation Plan for Countering Biological Threats, Enhancing Pandemic Preparedness, and Achieving Global Health Security (NBS); and lessons learned from the coronavirus disease 2019 (COVID-19) pandemic response--to posture DoD to counter biothreats through 2035. Developments in biological technology (biotechnology) are driving an increase in the scope and diversity of biothreats that DoD could face in the next decade. Additionally, as the planet's climate continues to change and its population grows, emerging infectious diseases are expected to develop and spread more frequently and potentially threaten DoD's readiness to achieve and maintain its national defense goals. The COVID-19 pandemic response presented opportunities for DoD to both improve its overall preparedness and posture, as well as to reinforce and reimagine its role in support of the broader U.S. Government and our allies and partners."

The Sociology of Privatized Security

USED BOOK. MAY CONTAIN MARK-UP

Edited by Ori Swed and Thomas Crosbie

FROM THE PREFACE: “This book started as a known unknown. We knew and admired the rich body of work being produced by political scientists, international relations scholars, legal scholars and historians (as well as a handful of sociologists) on the emerging private military and security industry. We knew about and were concerned with the political consequences of this development, with its nasty barbs of undermining legitimacy, stability and professionalism in the conduct of war and security operations. And we knew that we didn't know what this meant from a sociological perspective. With time, this known unknown transformed before our eyes into an unknown known. In other words, we realized that many of our fellow sociologists were as concerned as we were with establishing and promoting a sociological perspective on the privatization of security. The problem changed from one of disciplinary neglect to one of disciplinary resistance. In The Sociology of Privatized Security, we present a collection of nine chapters written by more than a dozen sociologists on a topic that is widely discussed in the public sphere but almost absent from the discipline. The book came about for that very reason: we want to bring this important topic into disciplinary discussion, to push our collcagues to take seriously the global trend toward privatizing security and military affairs as something that really matters to contemporary societies and to social life…”

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.

Creating Safe and Healthy Neighborhoods with Place-based Violence Interventions

By Bernadette C. Hohl, Michelle C. Kondo, Sandhya Kajeepeta, John M. MacDonald, Katherine P. Theall, Marc A. Zimmerman, and Charles C. Branas

Violence is a leading cause of death and disability in the United States and abroad, with far-reaching consequences for individuals and communities. Interventions that address environmental and social contexts have the potential for greater populationwide effects, yet research has been slow to identify and rigorously evaluate these types of interventions to reduce violence. Several urban communities across the US are conducting experimental and quasi-experimental community-based research to examine the effect of place-based interventions on violence. Using examples from Philadelphia, Pennsylvania; Flint, Michigan; Youngstown, Ohio; and New Orleans, Louisiana, we describe how place-based interventions that remediate vacant land and abandoned buildings work to reduce violence. These examples support the potential for place-based interventions to create far-reaching and sustainable improvements in the health and safety of communities that experience significant disadvantage. These interventions warrant the attention of community stakeholders, funders, and policy makers.

Safe Cities profile series: Key indicators by census metropolitan area

By Shana Conroy, Cristine Rotenberg, McKenzie Haringa and Sarah Johnston-Way

The Safe Cities profile series provides the most recent data on community safety and crime, and other social characteristics, for Canada’s census metropolitan areas (CMAs). Key indicators include community safety and sense of belonging, self-reported experiences of victimization, and police-reported crime—which are based on results from the General Social Survey on Canadians’ Safety (Victimization), the new Survey of Safety in Public and Private Spaces, and the Uniform Crime Reporting Survey. To complement community safety and crime data, CMA-level statistics from supplementary data sources are also provided, including population and demographics; education, employment and income; and housing and families. Efforts to promote community safety and well-being are central to Canada’s actions to achieve the United Nations’ Sustainable Development Goals (SDGs), which are part of the 2030 Agenda for Sustainable Development. The SDGs provide a shared blueprint for peace and prosperity, and they were adopted by all United Nations Member States in 2015. The SDGs mark an urgent call for action by all countries—both developing and developed—in a global partnership to address safety and security issues at home and abroad. They include a focus on ending inequality and gender-based violence while promoting sustainable cities, communities and institutions in the pursuit of peace and justice (Employment and Social Development Canada 2019).

Effects of neighborhood upgrading programs on domestic violence in Bolivia

By Nora Ruth Libertun de Duren

Landlocked in the center of South America, Bolivia experienced rapid urbanization only in recent decades. Its urban population became a majority in the 1990s, almost three decades later than the rest of Latin America’s southern cone. However, the country has made up for lost time since then with a very sharp transition from a rural to an urban society. The 2012 urbanization rate was 6.75 percent, more than four times the average for the rest of the region. Currently, one in three urban residents in Bolivia is a rural migrant who arrived in a city between 2006 and 2011 (Trohanis, Zaengerling, & Sanchez-Reaza, 2015). By 2025, three-quarters of Bolivia’s projected 14 million people will live in cities (UN-DESA, 2012). As in many developing countries, the majority of rural migrants in Bolivia settle in informal neighborhoods in peripheral areas of the country’s largest cities. It is estimated that 45 percent of Bolivia’s urban residents reside in an informal neighborhood (IDB, 2016). The housing units in these neighborhoods often resemble rural dwellings; they are usually self-built, and they are not connected to basic services such as water and sanitation. The neighborhoods frequently have unpaved, fuzzily demarcated, and unlighted roads of diverse widths. Accordingly, property boundaries among residents are blurry and may lead to conflicts among neighbors. Nevertheless, lack of formal titles does not preclude the existence of an active real estate market (Birch et al., 2016). Properties are traded and leased. There is an important income inequality within informal neighborhood residents; those who rent tend to be significantly poorer than those who own property (Talukdar, 2018). Typically, informal neighborhoods residents are more exposed to violence and insecurity, given that police and firemen do not often service these neighborhoods (Perlman, 2010). While there are no official crime statistics in Bolivia for these neighborhoods, residents report a high sense of insecurity (Gamboa, 2014); a phenomenon seen in informal neighborhoods in other countries, too (Parks, 2014). Also, while there are no formal statistics on violence against women, its main risk factors. -family history, early cohabitation, alcohol abuse, and low level of education- (Klugman et al., 2014)- are highly prevalent in informal neighborhoods (McIlwaine, 2013).
