  Biased highway troopers may intentionally misreport the race of the stopped motorists in order to evade detection. I develop a new model of traffic stops that highlights the incentive for biased troopers to misreport their failed minority searches as White. Applying my model to the universe of highway searches in Texas from 2010–2015, I find evidence of widespread bias that varies substantially across troopers. Furthermore, misreporting increased the Hispanic search success rate by 17%. When misreporting became more difficult due to public scrutiny, misreporting troopers faced worse labor outcomes. This suggests an important role for increased accountability in data collection by law enforcement agents.

This open access book brings together insights into Pacific policing, conceptualising policing broadly as order maintenance involving the actions of multiple local, regional and international actors with sometimes competing and conflicting agendas. A complex and multifaceted endeavour, scholarship on this topic is relatively scarce and widely dispersed across diverse sources. It examines how Pacific policing is shaped by changing state-society relations in different national contexts and ongoing processes of globalisation. Particular attention is given to the plural character of Pacific policing, profound challenges of gender equity, changing dynamics of crime, and the prominence of transnational policing in resource and capacity constrained domestic environments. The authors draw on examples from across the Pacific islands to provide a nuanced and contextualised account of policing in this socially diverse and rapidly transforming region.

How can we get more ‘output,’ and of the right sort, from policing? The question has only taken on greater importance with recent, widely publicized instances of police misconduct; declines in public trust in police; and a rise in gun violence, all disproportionately concentrated in economically disadvantaged communities of color. Research typically focuses on two levers: (1) police resources, and (2) policing strategies or policies, historically focused on crime control but increasingly also on accountability, transparency, and fairness. Here we examine a third lever: management quality. We present three types of evidence. First, we show there is substantial variability in violent crime and police use of force both across cities and within a city across police districts, and that this variation is related to the timing of police leader tenures. Second, we show that an effort to change police management in selected districts in Chicago generates sizable changes in policing outcomes. Third, as part of that management intervention the department adopted a predictive policing tool that randomizes which high-crime areas it shows to officers. We use that randomization to generate district-specific measures of implementation fidelity and show that, even within the context of a management intervention designed to improve implementation of the department’s strategies, there is variability in implementation.

This paper examines the impact of police funding on the fraction of homicides that are cleared by arrest. Using data covering homicides in approximately 50 of the largest US cities from 2007 to 2017, I find no evidence that greater police funding resulted in higher homicide clearance rates. This finding is robust to linear regression and instrumental variable approaches, different ways to measure police budgets, and across victims of different races and in different types of neighborhoods. In summary, the way large city police departments have historically spent their funds, more funding has not helped catch more murderers.

We report the first empirical estimate of the race-specific effects of larger police forces in the United States. Each additional police officer abates approximately 0.1 homicides. In per capita terms, effects are twice as large for Black versus white victims. At the same time, larger police forces make more arrests for low-level “quality-of-life” offenses, with effects that imply a disproportionate burden for Black Americans. Notably, cities with large Black populations do not share equally in the benefits of investments in police manpower. Our results provide novel empirical support for the popular narrative that Black communities are simultaneously over and under-policed.

Objective.This study analyzes the relationship between the race of a city’s police chief and the incidence of fatal shootings by police officers.Methods.The Washington Post’s “Fatal ForceDatabase” is used to calculate per-capita rates of fatal shootings by police officers occurring between January 1, 2015 and June 1, 2020 for the 100 largest cities in the United States. I compare fatal shooting rates for cities with police chiefs of different races, both unadjusted and adjusted for differences in city characteristics.Results.Rates of fatal shootings by officers are almost 50 percenthigher in cities with police forces led by white police chiefs than in cities with black police chiefs.Of the 30 cities with the highest rates of fatal shootings, 23 have police departments led by whites and only four have departments led by blacks, while of the 30 cities with the lowest rates, 16 have police departments led by blacks and only 11 are led by whites. Differences in fatal shooting rates persist after controlling for city characteristics.Conclusion.Leaders in the highest position of au-thority may have a powerful effect on the culture of a police department and its resulting behavior.Each year, there are approximately 1,000 fatal shootings by police officers across theUnited States, a statistic that has been fairly steady over the course of the last several years.With recent efforts to track and compile more comprehensive data, researchers have been increasingly studying the factors that contribute to these deaths. Prior research has looked at many factors surrounding fatal officer-involved shootings, including racial and demo-graphic information of both officers and victims, situational and location characteristics,and structural and organizational factors. This study contributes to the literature by look-ing at one as of yet unstudied factor: the race of a city’s police chief.Much of the prior work on police shootings has focused on the demographics of vic-tims. Edwards, Lee, and Esposito (2019) show that age and race are significant factors in determining the risk of being killed by police. Specifically, individuals between the ages of20 and 35 have the highest risk of all different age groups. They also find that blacks, Latinos, and Native Americans are significantly more likely to be killed by police than whites. An important distinction between sheriffs and police chiefs (or commanders, commissioners, captains,and superintendents) is that sheriffs are directly elected, while other top leaders are appointed by the mayor or city council. Sheriff’s departments also may have additional duties for their jurisdictions including supervision of correctional facilities and providing court security. There are only two cities in the data with elected sheriffs,and the analysis is not affected by eliminating these two departments.

The author of this report notes that recruitment and retention are critical issues in law enforcement, and that in order to address those issues, many agencies consider implementing a type of flexible scheduling called job sharing, in which two people share the duties of a single position while dividing the benefits. The author suggests that law enforcement agencies that are unable to implement job sharing may be able to utilize other flexible scheduling arrangements such as part-time positions or extended leave for qualifying events. The author identifies potential benefits of job sharing, including the retention of two people on one salary, improves employee work-life balance, reduces stress and burnout, supports greater productivity, and more. Potential drawbacks discussed by the author include training and equipping two people for one position, more employees to supervise and evaluate, it may require benefit reduction for job sharers, and it may not be allowed by local union contracts or local laws. The author makes several recommendations for the implementation of job sharing programs, including to conduct a focus group or survey to gauge interest in such a program, to identify and evaluate state legislation and local ordinances that may affect the implementation of job sharing, evaluate which units may benefit from a job sharing program and develop specific policies for those units and the specific positions, train employees and supervisors on the topic, and once a program has been implemented, to conduct ongoing evaluations. Alternative options to job sharing may include other types of flexible scheduling, such as the expansion of part-time officers and assignments, working from home, or extended leave policies. The author suggests that proper implementation can improve both recruitment and retention for police agencies as well as prolong officers’ careers and alleviate staffing shortages.

In the summer of 2019, Vallejo officials were responding to a time of transition for the City’s Police Department. The chief was newly retired, and the search for a new leader was underway against a backdrop of recent incidents – including fatal officer-involved shootings – that had prompted public concern and even demonstrations. It seemed as if a number of individual encounters were fitting all too well into larger, troubling narratives about American law enforcement: deadly force under disputed circumstances that affected minority subjects to a disproportionate extent, and strained relationships with residents that arose from and contributed to that reality while raising issues of trust and public confidence. Leadership within Vallejo’s city government decided that the time was right to take a step back and to assess the Department’s strengths, challenges, and opportunities in a new way. The City engaged an outside consultant to conduct this assessment.

This report is the product of that review. It was prepared by OIR Group, a team of private consultants that specializes in police practices and the civilian oversight of law enforcement. Since 2001, OIR Group has worked exclusively with government entities in a variety of contexts related to independent outside review of law enforcement, from investigation to monitoring to systems evaluation. Our members have provided oversight in jurisdictions throughout California, as well as in several other states.

 In 2019, the Chicago Police Department, in partnership with the Policing Project at New York University (NYU), implemented the Chicago Neighborhood Policing Initiative (CNPI). This initiative is composed of two interrelated goals: To measure CNPI’s impact, CORNERS built a multi-method research design capturing perspectives of residents and police in CNPI districts through in-depth interviews, systematic observations at police and community meetings and events, quasi-experimental statistical analyses, and analysis of key documents detailing CNPI activities.

This document was developed through efforts by the U.S. Department of Homeland Security’s (DHS) Homeland Security Advisory Council (HSAC or Council) Intelligence and Information Sharing Working Group, to develop guidelines for local and state agencies in relation to the collection, analysis, and dissemination of terrorism-related intelligence (i.e., the fusion process). Those efforts laid the foundation for the expansion of the Fusion Center Guidelines to integrate the public safety and private sector entities. The guidelines are intended to ensure that fusion centers are established and operated consistently, with enhanced coordination efforts, strengthened partnerships, and improved crime-fighting and antiterrorism capabilities. Key elements include: sector-specific information and sharing plans; identification of goals for the fusion center; creation of a representative governance structure and collaborative environment for intelligence sharing among local, state, tribal, and federal law enforcement agencies, public safety agencies, and the private sector; utilization of memoranda of understanding (MOUs), non-disclosure agreements (NDAs), and other agency agreements, as appropriate; leveraging of databases, systems, and networks to maximize information sharing; creating environments that promote communication among entities; development and publication of privacy and civil liberties policies; ensuring appropriate security measures for the facility, data, and personnel; integration of technology, systems, and people; achievement of a diversified representation of personnel based on the needs and functions of the center; ensuring adequate personnel training; provision of multitiered educational program for intelligence-led policing and information sharing; offering a variety of intelligence services and products to customers; developing and adhering to a policies and procedures manual; defining expectations and performance measurement for determining effectiveness; establishing and maintaining the center based on funding availability and sustainability; and the development and implementation of a communications plan among personnel, officers, and the general public. The eighteen guidelines provided reflect those key concepts; the document includes eight appendices.

The Center for Public Safety Management, LLC (CPSM) was commissioned to review the operations of the Little Rock Police Department. While our analysis covered all aspects of the department’s operations, particular areas of focus of this study included: identifying appropriate staffing of the department given the workload, community demographics, and crime levels; the effectiveness of the organizational structure; and efficiency and effectiveness of division/unit processes. We analyzed the department workload using operations research methodology and compared that workload to staffing and deployment levels. We reviewed other performance indicators that enabled us to understand the implications of service demand on current staffing. Our study involved data collection, interviews with key operational and administrative personnel, focus groups with line level department personnel, on-site observations of the job environment, data analysis, comparative analysis, and the development of alternatives and recommendations. Based upon CPSM’s detailed assessment of the Little Rock Police Department, it is our conclusion that the department, overall, provides quality law enforcement services. The staff is professional and dedicated to the mission of the department. Through this report, we will strive to allow the reader to take a look inside the department to understand its strengths and its challenges. We sincerely hope that all parties utilize the information and recommendations contained herein in a constructive manner to make a fine law enforcement agency even better. As part of this Executive Summary, we offer general observations that we believe identify some of the more significant issues facing the department. Additionally, we also list key recommendations for consideration; we believe these recommendations will enhance organizational effectiveness. Some of these recommendations involve the creation of new job classifications; others involve the reassignment/repurposing of job duties to other sections and units. Oftentimes these types of recommendations require a substantial financial commitment on the part of a jurisdiction. In the case of the Little Rock Police Department, some may be accomplished by a realignment of workload and/or reclassification of job descriptions. It is important to note that in this report we will examine specific sections and units of the department and will offer a discussion of our observations and recommendations for each.

• More...

  The list of recommendations is extensive. Should the Little Rock Police Department choose to implement any or all recommendations, it must be recognized that this process will not take just weeks or even months to complete, but perhaps years. The recommendations are intended to form the basis of a long-term improvement plan for the city and department. It is important that we emphasize that this list of recommendations, though lengthy, is common in our operational assessments of agencies around the country and should in no way be interpreted as an indictment of what we consider to be a fine department. While all of the recommendations are important, we suggest the Little Rock Police Department in conjunction with other city departments, the city council, the city manager, and members of the community decide which recommendations should take priority for implementation.

  This paper shows that shootings are predictable enough to be preventable. Using arrest and victimization records for almost 644,000 people from the Chicago Police Department, we train a machine learning model to predict the risk of being shot in the next 18 months. Out-of-sample accuracy is strikingly high: of the 500 people with the highest predicted risk, almost 13 percent are shot within 18 months, a rate 128 times higher than the average Chicagoan. A central concern is that algorithms may “bake in” bias found in police data, overestimating risk for people likelier to interact with police conditional on their behavior. We show that Black male victims more often have enough police contact to generate predictions. But those predictions are not, on average, inflated; the demographic composition of predicted and actual shooting victims is almost identical. There are legal, ethical, and practical barriers to using these predictions to target law enforcement. But using them to target social services could have enormous preventive benefits: predictive accuracy among the top 500 people justifies spending up to $134,400 per person for an intervention that could cut the probability of being shot by half.

Between 2016 and 2021, more than 400 unarmed people were killed by police during traffic stops. In addition, metropolitan areas that rely more on revenue from fines and fees experience more police killings. This study analyzed over 2,700 U.S. municipalities from 2009 to 2018 to describe the type of municipalities that collect the most money in monetary sanctions and investigate whether killings by police are more frequent in places that rely on fines and fees revenue. The author found that suburbs with larger Black populations rely the most on revenue from monetary sanctions and that municipalities that rely on such revenue have more police killings. This suggests municipalities’ fiscal landscape not only influences police contact with the public but also influences police violence.

Cash bail payments are generally imposed to ensure an individual appears in court after arrest. Lesser known is the practice of bond conversion, wherein bond money is held to pay for legal financial obligations if the individual is found guilty. Procedural justice theory is a useful framework for understanding bail processes. Individuals subject to bond conversion may experience distrust towards a system whose policies are not transparent, potentially reducing compliance with the law. We conduct an assessment of statutes relevant to bond conversion for all 50 states and the US Code. Nearly half of all states and the US Code permit bond conversion via statute; statutes most often authorize conversion to pay for fines, costs, and restitution; most do not require the depositor be given notice, do not include language making exceptions for low-income individuals, and do not exclude third parties.

  We estimate the causal impact of financial sanctions in the U.S. criminal justice system. We utilize a regression discontinuity design and exploit two distinct natural experiments: the abrupt introduction of driver responsibility fees (DRF) in Michigan and Texas. These discontinuously imposed additional surcharges ($300–$6,000) for criminal traffic offenses. Although the policies generated almost $3 billion of debt, we find consistent evidence that the DRFs had no impact on recidivism, earnings, or romantic partners’ outcomes over the next decade. Without evidence of a general or specific deterrence effect and modest success with debt collection, we find little justification for these policies.

The proliferation of counterfeits for sale on e-commerce sites has created new and more dangerous challenges to brand owners than counterfeits sold through brick and mortar establishments. Most brand owners are currently focusing their efforts on simplifying and streamlining Notice and Takedown (“NTD”) procedures set up by ecommerce platforms to remove illegal listings. The shortcomings of these efforts are that NTDs do not directly reach the counterfeiter who remains free to conduct its illegal activities with impunity and that NTDs do not prevent delisted counterfeiters from reappearing in short order under a new fictitious name and identity. Brand owners should seek to induce China to rigorously enforce its recently enacted Electronic Commerce Law (“ECL”), which was designed by China’s lawmakers to create a “choke point” that excludes counterfeiters and other unscrupulous merchants from gaining access to online accounts. The ECL requires multiple layers of government review and approval that were designed so that they can be satisfied only by legitimate and economically viable business entities. To date, e-commerce sites in China do not strictly comply with the ECL, and U.S.-based ecommerce sites do not require any compliance whatsoever with the ECL. Rigorous enforcement of the ECL should result in preventing counterfeiters from gaining access to e-commerce sites based in China and the United States and should lead to a decrease in sales of counterfeits on the internet.

Whatever our postcode or the colour of our skin, we all deserve to grow up in communities where we are cared for and given the tools we need to flourish in life. But instead of investing in young people or providing support to deal with the causes of social problems, the government has given the police more powers to try and tackle the symptoms of these issues. This has led to more and more people being treated unfairly by the police, rather than being given the help they need. Our communities need investment, so that together we can create spaces and services that we know will give our young people the best chance in life. And we need to roll back the powers of the police so no-one faces harsh and traumatising treatment at the hands of police. That’s why a coalition including Liberty, have launched a groundbreaking report calling for a new approach to tackling serious youth violence, with the powers of the police rolled back and more funding and support given for young people to thrive.,

Police stops are associated with reductions in crime but also a broad range of negative individual-level outcomes.

Police stop interventions produce meaningful and significant reductions in crime without evidence of spatial displacement. However, people subject to stops are associated with significantly less desirable mental and physical health outcomes, attitudes toward police, and self-reported crime/delinquency. For some outcome measures, the negative effects of pedestrian stops are considerably more pronounced for youth, though the data did not permit a comparison of individual effects by race.

What is this review about?

Police stops have become one of the most controversial yet widely-used crime prevention strategies in modern policing. This intervention involves the police-initiated stop of an individual (or group of individuals) on the street, for the purpose of investigation and/or questioning. Police stops have been commonly used as a tactic to combat violent and gun-related crime.

  Predictive policing algorithms are increasingly used by law enforcement agencies in the United States. These algorithms use past crime data to generate predictive policing boxes, specifically the highest crime risk areas where law enforcement is instructed to patrol every shift. I collect a novel dataset on predictive policing box locations, crime incidents, and arrests from a major urban jurisdiction where predictive policing is used. Using institutional features of the predictive policing policy, I isolate quasi-experimental variation to examine the causal impacts of algorithm-induced police presence. I find that algorithm-induced police presence decreases serious property and violent crime. At the same time, I also find disproportionate racial impacts on arrests for serious violent crimes as well as arrests in traffic incidents i.e. lower-level offenses where police have discretion. These results highlight that using predictive policing to target neighborhoods can generate a tradeoff between crime prevention and equity.
