Against Serious Violence Reduction Orders: discriminatory, harmful and counterproductive

By Tim Head

Serious Violence Reduction Orders (SVROs) are a new police stop and search power, being piloted by forces in England and Wales. Introduced under the controversial Police Crime Sentencing and Courts Act (2022), SVROs are part of a broader expansion of police powers and the rolling back of safeguards and avenues for police accountability. The Home Office itself has admitted that many of the potential harmful consequences of SVROs will likely fall on people of colour, on Black people in particular. In “Against SVROs”, we review the evidence around high-discretion police powers similar to SVROs, which overwhelmingly shows that they do not work to reduce serious violence. Contrary to the government's claim that SVROs will "break the cycle of offending”, we found that high-discretion police powers and behavioural orders push people, disproportionately people of colour, into the criminal justice system. These policing interventions are clearly evidenced to harm the mental and physical health of those targeted, while reproducing deep-seated racial discrimination in the use and abuse of police powers.

Voluntary Interviews: Police Use of Voluntary Interview and the Application of the Appropriate Adult

By Chris Bath

Police forces in England and Wales carried out an estimated 145,000 voluntary interviews under caution in 2022/23, of which around one fifth were of children. Only 4.8% of adults attending a voluntary interview were recorded as meeting the criteria for appropriate adult (AA) support – around half the rate in police custody. While custody rightly attracts scrutiny, this report highlights both why and how a strategic focus should be brought to bear on voluntary interviews. Part 1 presents an analysis of quantitative data provided by police forces. Part 2 sets out the policy and practice challenges from the perspective of local appropriate adult scheme leaders.

Going cyberpunk: Conceptualizing the smart(er) artificially intelligent firearm for policing's Utopian future

By Mehzeb Chowdhury

As policing develops into a more professional, evidence-driven and technical endeavour, heightened public concern regarding organizational competence and police culture-related fallacies have become augmented, especially in the case of officer-involved shootings. Introduction of body-worn cameras, increased CCTV coverage, vehicle dash-cams and the advent of social media, have provided avenues for investigation into misconduct, but institutional and individual failings such as racism, sexism and other forms of discrimination remain a concern. Technical innovations like smart guns, smart targeting and programmable projectiles have instigated conversations about traditional firearms and whether alternatives using cutting-edge technology could address some of these shortcomings. This article examines existing policing technologies, providing an overview of advanced computational and sensor systems, the risks and dangers of these mechanisms, as well as their potential benefits and drawbacks. It conceptualizes whether existing technologies can be transformed into a smarter, more efficient firearm, powered by artificial intelligence (AI). The premise of the AI-assisted firearm being the promise of a future in which unwanted outcomes in officer/citizen encounters can be counteracted through AI assisting in better decision-making. The article considers hardware and software, policy issues, associated risks and potential advantages of the firearms system, providing a wider perspective on the increasing use of computational technologies in policing practice, and highlighting areas for further research and discussion.

Local Police Departments, Procedures, Policies, and Technology, 2020 – Statistical Tables

By Sean E. Goodison,  and Connor Brooks

In 2020, 57% of local police departments almost always or always authorized oleoresin capsicum (OC) spray or foam, and 53% almost always or always authorized conducted energy devices, such as Tasers and stun guns (figure 1). Figure 1 displays the authorization of less-lethal equipment and techniques in 2020. Less-lethal equipment and techniques are weapons and tactics that are not intended to cause death or serious injury. Among less-lethal techniques, 73% of local police departments almost always or always authorized open-hand techniques and another 25% authorized them in  limited circumstances. Similarly, about 65% of departments almost always or always authorized takedown techniques and another 31% authorized them under limited circumstances. Conversely, more than half (59%) of local police departments never authorized vascular restraints or carotid holds. About 69% of local police departments never authorized respiratory neck restraints, while 29% did so under limited circumstances and 1% almost always or always authorized them.  This report uses selected variables from the 2020 Law Enforcement Management and Administrative Statistics (LEMAS) data collection, conducted by the Bureau of Justice Statistics (BJS), to describe equipment, policies, and procedures in local police departments by population served. Additionally, this report describes the percentage of officers who work in departments with said equipment, policies, and procedures. Local police departments include general-purpose law enforcement agencies such as municipal, county, and regional police departments, but exclude other types of general-purpose law enforcement agencies, such as sheriffs’ offices and primary state and highway patrol agencies. For information on personnel in local police departments, see Local Police Departments Personnel, 2020 (NCJ 305187, BJS, November 2022). Findings in this report are primarily based on the 2020 LEMAS survey. Conducted periodically since 1987, the LEMAS survey collects data on a range of topics from a nationally representative sample of general-purpose state and local law enforcement agencies. (See Methodology in Local Police Departments Personnel, 2020 (NCJ 305187, BJS, November 2022).)

Improving Learning Outcomes in Police Academy Training

By Dianne Beer-Maxwell, Jon Blum, Timothy Bonadies, Jessica Herbert, and Peggy Schaefer

When performing official duties, law enforcement officers rely heavily on knowledge and skills learned during basic academy training. Entry-level law enforcement training is typically delivered in topic-centric classes with little or no connection between concepts, despite significant content overlap. For example, an understanding of search and seizure law is applicable across many contexts, including in lessons about motor vehicle stops, arrests, investigation, use of force, and interview and interrogation. Similarly, communication skills are needed across the board to be effective at interviewing people, de-escalating violent situations, and building relationships with the community. Existing research from other professions recommends integrating or reinforcing foundational and overlapping content consistently to help people retain critical knowledge and skills. The concept of integrating and reinforcing training content consistently has not previously been tested in law enforcement. The Academy Innovations project evaluates the results of reinforcing a critical foundational skill across multiple topics through use of an integrated curriculum in a basic academy setting. In this guide we will 1. introduce and define the concepts of integrated curriculum and retention interval; 2. explain a groundbreaking study that examined the effects of integrated curriculum on retention interval in five law enforcement academies; 3. present eight best practices for integrating curricula in law enforcement academies.

Influence Policing:: Strategic communications, digital nudges, and behaviour change marketing in Scottish and UK preventative policing

By  Ben Collier , James Stewart , Shane Horgan, Lydia Wilson and Daniel R. Thomas 

Influence policing is an emerging phenomenon: the use of digital targeted ‘nudge’ communications campaigns by police forces and law enforcement agencies to directly achieve strategic policing outcomes. While scholarship, civil society, and journalism have focused on political influence and targeting (often by malicious actors), there has been next to no research on the use of these influence techniques and technologies by governments for preventative law enforcement. With grant funding from SIPR and support from The Scottish Centre for Crime and Justice Research (SCCJR), we have studied how this novel mode of police practice is developing through an in-depth study of Police Scotland’s strategic communications unit and a wider systematic overview of these campaigns across the UK. Key findings: Police Scotland . Since 2018, Police Scotland has had a dedicated team devoted to strategic communications marketing campaigns - developing methods for crime prevention through communications. These adapt classic forms of ‘strategic communications’ and ‘social marketing’ to incorporate novel techniques and tools, tailoring them to crime prevention - particularly the use of behaviour change theory and digital targeting and segmentation infrastructures. These influence (including ‘nudge’) communications go beyond ‘information’ campaigns or those which simply tell or ask the public to do something, and instead incorporate psychological design elements which attempt to alter the decision environment in which members of the public make choices about their behaviour - often linking up with other interventions such as the redesign of public services.  In a wider policing context, these innovations can be understood as a development of problem-oriented and intelligence-led policing models in a digital context. The campaigns - focusing on areas with a perceived ‘online’ component, such as violence against women and girls, online grooming, and hate crime - are conceived as part of a public health prevention approach, often using perpetrator-focused adverts to deliver messages to those profiled as ‘at risk’ of offending. This is part of a move away from campaigns which simply rely on telling the public what to do, or which focus on putting the responsibility for crime prevention on victims. There are two main elements to campaigns - the first are attempts to directly change people’s behaviour through ‘nudge’ communications, and the second are wider attempts to shape the cultural narratives that are perceived to contribute to crime.  In Scotland, digital targeting is mostly used at the broad demographic level (i.e. age and gender), although some use of fine-detail location and interest-based targeting is evident.  Online targeted paid advertising is used in conjunction with conventional media buying, and organic and ‘earned’ communication with stakeholders and civil society partners.  Campaigns are largely developed in house, but the media buying and some campaign development is done with commercial advertising and marketing partners. Civil Society stakeholders play a key role in consultation and development of campaigns, and in the ‘organic’ promotion.  The digital platforms themselves play a major role in shaping what is possible, sometimes redirecting the intervention through algorithmic processes or promoting organic sharing.  Evaluation of the campaigns is able to use some outcome measures but also still relies heavily on ‘vanity’ metrics (such as apparent views and click throughs) provided by the platforms - and effects are difficult to measure.  The use of influencers (usually well-known public figures) in some campaigns to amplify messages is a clear innovation - though raises some concerns. These influencers have legitimacy with and knowledge of targeted communities, and generally retain their audiences across multiple platforms (even when these platforms change or fail).  We suggest the term Influence officers to describe the professional police communications specialists who design and develop these campaigns, who represent a growing new role in ‘frontline’ policing. The centralised unit and single national force structure in Scotland has had some positive effects when compared to English forces, providing mechanisms for accountability (and saying ‘no’ to unsuitable or harmful campaigns) where more formal structures don’t yet exist. However, this is reliant on the tacit knowledge and expertise of a small group of practitioners - and some aspects of this approach would benefit from being on a more formal institutional footing.  Despite its proliferation across the UK, this is a distinctively Scottish mode of ‘influence policing’ and the ‘influence officer’ as a possible emerging role within policing.

Policing the Police: Personnel Management and Police Misconduct

By Max Schanzenbach

Police misconduct is at the top of the public policy agenda, but there is surprisingly little understanding of how police personnel management policies affect police misconduct. Police-civilian interactions in large jurisdictions are, in principle at least, highly regulated. But these regulations are at least partially counteracted by union contracts and civil service regulations that constrain discipline and other personnel decisions, thereby limiting a city’s ability to manage its police force. This Essay analyzes police personnel management by bringing forth evidence from a variety of data sources on police personnel practices as well as integrating an existing, but relatively siloed, literature on police misconduct. The empirical findings that emerge are as follows: (1) policing is a surprisingly secure, well-paid job with little turnover prior to retirement age; (2) inexperienced police officers are, all else equal, more likely to commit misconduct and, at the same time, more likely to receive high risk assignments; and (3) bad cops are a serious problem, are identifiable, and are rarely removed or disciplined. Taken together, these facts suggest that attempts to regulate police conduct directly or through civil rights litigation are impeded by the inability of those who supervise police to control individual officers through assignments, discipline, and removal. The nexus of compensation, seniority, promotion, discipline, and pension policies that characterize much police personnel management cannot be rationalized under traditional labor and employment contract analysis. Existing compensation  and pension policies could be rationalized, however, if supervisors were empowered to manage police through assignments, penalties, and promotion.

Are Police Officers Bayesians? Police Updating in Investigative Stops

By Jeffrey Fagan and Lila Nojima

Theories of rational behavior assume that actors make decisions where the benefits of their acts exceed their costs or losses. If those expected costs and benefits change over time, the behavior will change accordingly as actors learn and internalize the parameters of success and failure. In the context of proactive policing, police stops that achieve any of several goals—constitutional compliance, stops that lead to “good” arrests or summonses, stops that lead to seizures of weapons, drugs, or other contraband, or stops that produce good will and citizen cooperation—should signal to officers the features of a stop that increase its rewards or benefits. Having formed a subjective estimate of success (i.e., prior beliefs), officers should observe their outcomes in subsequent encounters and form updated probability estimates, with specific features of the event, with a positive weight on those features. Officers should also learn the features of unproductive stops and adjust accordingly. A rational actor would pursue “good” or “productive” stops and avoid “unproductive” stops by updating their knowledge of these features through experience. We analyze data on 4.9 million Terry stops in New York City from 2004–2016 to estimate the extent of updating by officers in the New York Police Department. We compare models using a frequentist analysis of officer behavior with a Bayesian analysis where subsequent events are weighted by the signals from prior events. By comparing productive and unproductive stops, the analysis estimates the weights or values—an experience effect—that officers assign to the signals of each type of stop outcome. We find evidence of updating using both analytic methods, although the “hit rates”—our measure of stop productivity including recovery of firearms or arrests for criminal behavior—remain low. Updating is independent of total officer stop activity each month, suggesting that learning may be selective and specific to certain stop features. However, hit rates decline as officer stop activity increases. Both updating and hit rates improved as stop rates declined following a series of internal memoranda and trial orders beginning in May 2012. There is also evidence of differential updating by officers conditional on a variety of features of prior and current stops, including suspect race and stop legality. Though our analysis is limited to NYPD stops, given the ubiquity of policing regimes of intensive stop and frisk encounters across the United States, the relevance of these findings reaches beyond New York City. These regimes reveal tensions between the Terry jurisprudence of reasonable suspicion and evidence on contemporary police practices across the country.

Use of extreme risk protection orders to reduce gun violence in Oregon

By April M. Zeoli, Jennifer Paruk, Charles C. Branas, Patrick M. Carter, Rebecca Cunningham, Justin Heinze and Daniel W. Webster

We examined petition and respondent characteristics from extreme risk protection order (ERPO) cases in Oregon for the 15 months after implementation (n = 93). Most petitions were filed by law enforcement (65%) a were more likely to be granted than petitions filed by family/household members (p < 0.001). Most ERPO respondents were reported by petitioners to have histories of suicidality (73%) or interpersonal violence (75%), with over half of death threats, suicide threats, or suicide attempts with known timing occurring within 1 week of the petition being filed. Policy Implications: ERPO petitions and orders are overwhelmingly being used as intended, that is, specifically for cases of imminent risk of harm to self or others. Greater dissemination of public information about ERPOs may increase their appropriate use and the proportion of high-risk individuals and families who may benefit. Legal aid assistance for family or household members in filling out petitions is advisable.

Detecting AI Fingerprints: A Guide to Watermarking and Beyond

By Srinivasan, Siddarth

From the document: "Over the last year, generative AI [artificial intelligence] tools have made the jump from research prototype to commercial product. Generative AI models like OpenAI's ChatGPT [Chat Generative Pre-trained Transformer] [hyperlink] and Google's Gemini [hyperlink] can now generate realistic text and images that are often indistinguishable from human-authored content, with generative AI for audio [hyperlink] and video [hyperlink] not far behind. Given these advances, it's no longer surprising to see AI-generated images of public figures go viral [hyperlink] or AI-generated reviews and comments on digital platforms. As such, generative AI models are raising concerns about the credibility of digital content and the ease of producing harmful content going forward. [...] There are several ideas for how to tell whether a given piece of content--be it text, image, audio, or video--originates from a machine or a human. This report explores what makes for a good AI detection tool, how the oft-touted approach of 'watermarking' fares on various technical and policy-relevant criteria, governance of watermarking protocols, what policy objectives need to be met to promote watermark-based AI detection, and how watermarking stacks up against other suggested approaches like content provenance."

People Seeking Asylum Confined Outside in Appalling Conditions: Findings and Recommendations from a Monitoring Visit to San Diego

By The Womens Refugee Commission

In October 2023, the Women’s Refugee Commission’s (WRC) Migrant Rights and Justice program visited San Diego, California, and Tijuana, Baja California, Mexico, to assess the conditions that people seeking asylum at the US-Mexico border face. We visited a migrant shelter and an encampment located between two border walls where migrants await apprehension, and volunteered to aid migrants and people seeking asylum following their release from immigration custody. We also met with local officials, nonprofit organization partners, and individuals seeking asylum. Based on what we learned, WRC compiled this report on our assessments and recommendations.

How Government Pay: Lawsuits, Budgets, and Police Reform

By Joanna C. Schwartz

For decades, scholars have debated the extent to which financial sanctions cause government officials to improve their conduct. Yet little attention has been paid to a foundational empirical question underlying these debates: When a plaintiff recovers in a damages action against the government, who foots the bill? In prior work, I found that individual police officers virtually never pay anything toward settlements and judgments entered against them. But this finding prompts another question: Where does the money come from, if not from individual officers? The dominant view among those who have considered this question is that settlements and judgments are usually paid from jurisdictions’ general funds with no financial impact on the involved law enforcement agencies, and some have suggested that agencies would have stronger incentives to improve behavior were they required to pay settlements and judgments from their budgets. But, beyond anecdotal information about the practices in a few large agencies, there has been no empirical inquiry into the source of funds used by governments to satisfy suits involving the police.

In this Article, I report the results of the first nationwide study to examine how cities, counties, and states budget for and pay settlements and judgments in cases against law enforcement. Through public records requests, interviews, and other sources, I have collected information about litigation budgeting practices in one hundred jurisdictions across the country. Based on the practices in these one hundred jurisdictions, I make two key findings. First, settlements and judgments are not always—or even usually—paid from jurisdictions’ general funds; instead, cities, counties, and states use a wide range of budgetary arrangements to satisfy their legal liabilities. All told, half of the law enforcement agencies in my study financially contribute in some manner to the satisfaction of lawsuits brought against them.

Second, having a department pay money out of its budget toward settlements and judgments is neither necessary nor sufficient to impose a financial burden on that department. Some law enforcement agencies pay millions from their budgets each year toward settlements and judgments, but the particularities of their jurisdictions’ budgeting arrangements lessen or eliminate altogether the financial impact of these payments on these agencies. On the other hand, smaller agencies that pay nothing from their budgets toward lawsuits may nevertheless have their very existence threatened if liability insurers raise premiums or terminate coverage in response to large payouts.

Chicago Police Department 911 Response Time Data Collection and Reporting

By City of Chicago, Office of Inspector General

The objectives of the inquiry were to determine the completeness rates of CPD response times recorded by CPD and the Office of Emergency Management and Communications (OEMC), and to identify factors contributing to missing response time data for 911 calls for CPD service.

As a result of this inquiry, OIG found that CPD’s data collection of 911 response times is incomplete; the Department fails to record timestamps for various statuses throughout the dispatch and police response for a substantial number of 911 calls. Calls for high priority emergency events had a higher rate of recorded response times for all statuses that occur during a unit’s response (Acknowledge, Enroute, and On-scene) compared to calls for events with a lower priority classification. The timepoint in the police response process that is least often recorded is the On-scene time, or the time when the responding CPD unit arrives at the location of service; this remains true regardless of call priority level or geographic location. The On-scene status is the last time point in the sequence of events before responding members engage with an emergency event, which may contribute to the low On-scene time completeness rates. Additionally, the interface of the Computer Aided Dispatch (CAD) system, which records a timestamp when CPD members enter their response status, displays the response status buttons sequentially, and is dependent on the previous status in the process being entered.

Perceiving social injustice during arrests of Black and White civilians by White police officers: An fMRI investigation

By Tzipporah P. Dang , Bradley D. Mattan , Denise M. Barth , Grace Handley, Jasmin Cloutier, Jennifer T. Kubota

From social media to courts of law, recordings of interracial police officer-civilian interactions are now widespread and publicly available. People may be motivated to preferentially understand the dynamics of these interactions when they perceive injustice towards those whose communities experience disproportionate policing relative to others (e.g., non-White racial/ethnic groups). To explore these questions, two studies were conducted (study 1 neuroimaging n = 69 and study 2 behavioral n = 58). The fMRI study examined White participants’ neural activity when viewing real-world videos with varying degrees of aggression or conflict of White officers arresting a Black or White civilian. Activity in brain regions supporting social cognition was greater when viewing Black (vs. White) civilians involved in more aggressive police encounters. Additionally, although an independent sample of perceivers rated videos featuring Black and White civilians as similar in overall levels of aggression when civilian race was obscured, participants in the fMRI study (where race was not obscured) rated officers as more aggressive and their use of force as less legitimate when the civilian was Black. In study 2, participants who had not viewed the videos also reported that they believe police are generally more unjustly aggressive towards Black compared with White civilians. These findings inform our understanding of how perceptions of conflict with the potential for injustice shape social cognitive engagement when viewing arrests of Black and White individuals by White police officers.

Policing Productivity Review: Improving outcomes for the public

By National Police Chiefs’ Council (UK)

This Review was established to ‘identify ways in which forces across England and Wales can be more productive, improving outcomes’1 . In the three fnancial years to March 2023, Government funded the recruitment of an additional 20,000 police ofcers. This – together with additional resources provided by precept - is a considerable investment into policing. As new recruits build up experience and capabilities, we would expect to see its impact in terms of public safety. Compared to 2007, ofcer numbers have increased seven per cent whilst the population has increased by about 12 per cent (and with it, demand). However, like-for-like comparisons are not necessarily helpful: technology for example should have made police forces more productive since then. But to a large extent we have found that if the uplift has helped fll the most urgent capacity gaps (and improve performance), it has not taken away the need to prioritise and task resources effectively. A productivity drive is as necessary now as it was in the years of officer reduction. An environment of budget pressures suggests difficult choices ahead for public sector investment. Public agencies will need to evidence, more than ever, that they are providing value for money and becoming more productive. Pouring additional resources into a service might create more outputs but it does not per se increase productivity if these resources are not used wisely. Neither do officer numbers guarantee reduced crime2. Effective resource allocation is essential to deliver the greatest gains. Coordinated planning and multi-agency collaboration are vital to maximise the chances of better public outcomes. In this context, as a prerequisite to further investment demands and to strengthening public legitimacy, it is imperative that the policing sector is able to demonstrate how it is making best use of its resources and what direct benefits its activity delivers to the public. THE OPERATING LANDSCAPE OF POLICING IS SHIFTING Policing demand has changed. Since the mid-1990s, there have been long-term falls in overall crime levels but since 2014, offences have risen again (while still 20 per cent below their 2002/03 level). New technologies have created new criminal opportunities: the Office for National Statistics (ONS) reports 3.8 million fraud offences and cyber-enabled, or cyber-dependent crimes, and even across “traditional” crimes, the Metropolitan Police Service assesses that two ffths of robberies and 70 percent of theft are for mobile phones. Technological advances can also give rise to investigative opportunities, and policing productivity (and its perceived effectiveness in using technology) can act as a deterrent to criminality. Some patterns of crime are less easy to read. Violent offences recorded by police increased, but the Crime Survey for England and Wales suggests a decrease. Recorded sexual offences have markedly increased . More victims are fnding the courage to come forward and report crimes such as rape, domestic abuse and the sexual exploitation of children. The recognition of vulnerability in victimisation has become a powerful element shaping policing since the death of Fiona Pilkington and her daughter in 2007. Because of these changes, policing today requires a very different skillset. In 2003, armed with a knowledge of three crime types (burglary, theft and criminal damage), a constable knew how to approach 80 per cent of the demand coming their way. In 2023, in order to manage the same proportion of their work, this constable has to be competent across six disparate and wider categories of crime: theft, fraud (including online), violence with injury, stalking and harassment, public order and violence without injury. Non crime demand on officers equally broadened in scope during that time.

It’s a matter of (change over) time: the role of police conduct on the dynamics of attitudes towards legal authority

By Thiago R. Oliviera

This thesis draws on procedural justice theory and work into legal socialisation and legal cynicism to investigate the dynamics of public perceptions of trustworthiness and legitimacy of legal authority over time. Illustrating how longitudinal data can be theoretically fruitful in studies on public-police relations, I rely upon several analytic strategies that exploit panel data to examine attitudinal change over time. To examine the development of legitimacy judgements during adolescence, the mutual reproduction of different aspects of police trustworthiness over time, and the degree to which police contact leads to attitudinal change, I draw on data from three longitudinal surveys, which are representative of the adult population living in selected neighbourhoods in S˜ao Paulo, Brazil, adolescents who live in S˜ao Paulo, and the adult population living in Australia. At the heart of the thesis are four empirical papers. The first paper suggests that perceptions of overpolicing and underpolicing undermine legitimacy judgements and mutually reproduce each other over time, with implications for people’s recognition of the ruling power of the law. The second paper focuses on the development of legitimacy judgements among adolescents, and shows that exposure to neighbourhood and police violence may damage the process of healthy legal socialisation. The third paper examines whether police-citizen encounters are teachable moments, with the potential of leading to either positive or negative attitudinal change depending upon the perceived appropriateness of the interaction. The fourth paper addresses the issue of causality – an important gap in the procedural justice literature. Analysis suggests that aggressive police stops (e.g., at gunpoint) have a shortterm effect on perceived police fairness and a long-term effect on perceived overpolicing. Overall, results indicate that reliance on coercive policing strategies have several social costs, including public detachment and alienation from from the law. Adolescents who witness cases of police brutality show diminished development in legitimacy judgements, and the experience or expectation that police officers repeatedly intrude in the lives of people (overpolicing) and fail to ensure public safety (underpolicing) undermine people’s recognition of the state’s monopoly of violence. Yet, there is room for improvement. Perceptions of procedural fairness seem to enhance police trustworthiness and legitimacy. In sum, results indicate that people develop legal attitudes throughout the life course, but police (mis)conduct can lead to attitudinal change over time.

Socialization through violence: Exposure to neighborhood and police violence and the developmental trajectories of legitimacy beliefs among adolescents in São Paulo.

By: Thiago R Oliveira, Johnathan Jackson, Renan Theodoro de Olivieria

Objectives: Examine the legal socialization of adolescents aged 11 to 14 years in São Paulo, Brazil, a city characterized by a high prevalence of police violence and organized crime. Assess the extent to which exposure to neighborhood and police violence and aggression influence adolescents’ developmental trajectories of beliefs about the legitimacy of the law.

Methods: A four-wave longitudinal survey of 2005-born adolescents living in São Paulo was fielded annually between 2016 and 2019 and measured respondents’ perceptions of legal legitimacy, exposures to neighborhood and police violence, and police contact. Adopting a life- course approach, developmental trajectories are estimated using quadratic latent growth curve models.

Results: Witnessing police officers assaulting a suspect, being involuntarily stopped by the police, and seeing people selling drugs on the street are all negatively associated with changes in legal legitimacy beliefs. Exposure to gunshots, gun-carrying, or robberies are not associated with changes in legitimacy beliefs.

Conclusions: Indicating that adolescents in São Paulo are socialized through violence, exposure to police violence and proximity to organized crime could undermine their development of legal legitimacy beliefs. Exposure to other episodes of neighborhood violence might be too frequent in this context and do not distinguish adolescents’ developmental trajectories of legitimacy beliefs.

The Laws that Regulate Police: The Wilson Center's Policing Legislation Database

By Brandon L Garrett

In the past three years, there has been a surge of lawmaking concerning policing at the federal, state and local levels, including in response to the killing of George Floyd in May 2020 and subsequent racial justice movements across the country. Unwarranted uses of force, including deadly force, are all too common in America, particularly for Black men. Unfortunately, legal barriers often prevent meaningful accountability in response to a crisis of poor police practices and actions. Some recent legislation has at times taken a more comprehensive approach towards the challenge of addressing injustices and rethinking public safety, while other legislation takes a targeted approach, and still additional legislation has addressed a range of newer issues concerning policing, including deployment of technology, data collection, officer wellbeing, behavioral health diversion, and funding. To better understand lawmaking in response to calls for reform, at the Wilson Center for Science and Justice, we began tracking the introduction of policing-related legislation in Spring 2020.1 Our database, which has been updated continually, includes over 3,800 bills — federal, state, and local — across a wide range of topics related to law enforcement from 2018 through 2022. This is the largest such database assembled.2 It is available here: policing legislation.law.duke.edu. The sheer breadth of the topics and the activity is remarkable, although only about 10 percent of these laws have been enacted. Further, we develop how counting legislation does not fully capture trends where some single pieces of legislation include wide-ranging provisions. In addition, legislation regulating police can accomplish a range of objectives and goals, including laws designed to both limit and empower local police, sometimes in the same legislation. We plan to update the database over time to track this legislation and also examine additional prior years.

Public Perceptions of Black Women and Girls and Their Punitive Consequences

By Sally Nuamah

How do race and gender stereotypes affect public support for the punishment of Black girls? Across the United States, Black girls are suspended, arrested, and detained at disproportionate rates. And yet, little research exists on these troubling patterns in public opinion research. Using an original survey experiment, this paper places the punitive experiences of Black girls at the center of research on American politics. The data illustrate the empirical link between the adultification of Black girls and public support for their punishment. In particular, it reveals that the American public views Black girls as older, more dangerous, and more knowledgeable about sex, thus influencing perceptions of them as deserving of harsher punishments than their peers. These findings have important implications for understanding the general public's potential role in shaping the punitive experiences of Black girls and raise questions about the consequences of their punishment for democracy.
