Opioids, including the highly potent synthetic opioids fentanyl and carfentanil, are commonly sold on illicit cryptomarkets or Tor darknet markets. Data collected throughout 2019 from 12 large darknet markets that sold opioids enabled observation of the impact of law enforcement seizures and voluntary or scam market closures on the availability of fentanyl and other opioids.

Trends in opioid and fentanyl availability before and after law enforcement interventions indicate whether market operators and sellers are deterred and whether market closures lead to displacement, dispersal or substitution. Evidence of all of these outcomes was present in both descriptive and trend analyses, although most effects were short lived. Market closures, especially law enforcement seizures, reduced the availability of opioids, in particular fentanyl, as well as increasing prices and displacing vendors to other markets. Market closures also led vendors to substitute fentanyl for other opioids or other illicit drugs.

The suicide rate for Black youth has increased by 60% between 2007 and 2020. Direct or vicarious racial trauma experienced through exposure to police brutality may underlie these concerning trends.MethodsWe obtained nationally aggregated monthly counts of suicides for non-Hispanic Black and White youth (age ≤ 24 years) and adults (age > 24 years) from the National Mortality Vital Statistics restricted-use data files provided by the Centers for Disease Control and Prevention, from 2013 to 2019. Monthly counts of Black youth suicides constituted our main outcome. We defined our exposure as the monthly counts of police killings of unarmed Black persons over 84 months (2013 to 2019), retrieved from the Mapping Police Violence database. We used ARIMA (AutoRegressive Integrated Moving Average) time-series analyses to examine whether Black youth suicides increased within 0 to 3 months following police killings of unarmed Black persons, controlling for autocorrelation and corresponding series of white youth suicides.ResultsSuicides among Black youth increase by ~1 count within three months following an increase in police killings of unarmed Black persons (coefficient=0.95,p<0.05), which approximates to about 267 suicides among Black youth over our study period. The observed increase in suicides concentrates among Black male youth.

Private security officers outnumber police by a wide margin, and the gap may be growing. As cities have claimed to defund the police, many have quietly expanded their use of private security, reallocating spending from the public to the private sector. It is difficult to know what to make of these trends, largely because we know so little about what private security looks like on the ground. On one prevalent view of the facts, a shift from public to private security would mean little more than a change of uniform, as the two labor markets are deeply intertwined. Indeed, academics, the media, popular culture, and the police themselves all tell us that private security is some amalgam of a police retirement community and a dumping ground for disgraced former cops. But if, instead, private officers differ systematically from the public police—and crossover between the sectors is limited—then substitution from policing to private security could drastically change who is providing security services.

We bring novel data to bear on these questions, presenting the largest empirical study of private security to date. We introduce an administrative dataset covering nearly 300,000 licensed private security officers in the State of Florida. By linking this dataset to similarly comprehensive information about public law enforcement, we have, for the first time, a nearly complete picture of the entire security labor market in one state. We report two principal findings. First, the public and private security markets are predominantly characterized by occupational segregation, not integration. The individuals who compose the private security sector differ markedly from the public police; they are, for example, significantly less likely to be white men. We also find that few private officers, roughly 2%, have previously worked in public policing, and even fewer will go on to policing in the future. Second, while former police make up a small share of all private security, roughly a quarter of cops who do cross over have been fired from a policing job. In fact, fired police officers are nearly as likely to land in private security as to find another policing job, and a full quarter end up in one or the other. We explore the implications of these findings, including intersections with police abolition and the future of policing, at the paper’s close.

FROM THE PREFACE: “In moving down through this nested hierarchy of organizational types, we reach one of the key steps at a level where the social units are distinct as unique cultural and political entities. What was peculiarly Byzantine, or peculiarly Chinese, about the perception of law-enforcement problems and responses and about the ways in which lawbreakers were treated? These attributes, which distinguish one such political entity from another, are simply parts of our definition of what it is to be Chinese or Byzantine or Roman. Such defining attributes evolve over time. The Chinese language has changed from the time of the Shang dynasty to today. However, the changes in these fundamental attributes are evolutionary, not revolutionary. Despite the ways in which it has changed, the Chinese language has remained the Chinese language..”

Police Custody in Ireland brings together experts from policing studies, law, criminology, and psychology, to critically examine contemporary police custody in Ireland, what we know about it, how it operates, how it is experienced, and how it might be improved. This first-of-its-kind collection focuses exclusively on detention in Garda Síochána stations, critically examining it from human rights and best practice perspectives. It examines the physical environment of custody, police interview techniques, existing protections, rights, and entitlements, and experiences of specific communities in custody, such as children, ethnic minorities, non-English speakers, the Mincéir/Traveller community, and those with intellectual disabilities or Autism Spectrum Disorder. Police Custody in Ireland gives a snapshot of garda custody as it is now and makes important recommendations for necessary future improvements. An accessible and compelling read, this book will be of interest to those engaged in policing and criminology, as well as related areas of interest such as human rights, youth justice and disability studies.

Law enforcement agencies continue to develop new and innovative strategies to better support and police the communities they serve, from integrating gunshot detection technologies into dispatch systems to improve response times during shootings, to collaborating with local health and social service organizations to address issues such as homelessness or substance abuse in comprehensively ways. Over the past 10 years, the Bureau of Justice Assistance (BJA), in partnership with the CNA Institute for Public Research (IPR), has supported law enforcement agencies across the country in implementing innovative policing approaches through the Strategies for Policing Innovation Initiative (SPI, formerly the Smart Policing Initiative). SPI supports not only the development and implementation of innovative policing strategies, but also the research partnerships that result in in-depth analyses and rigorous evaluations of these strategies to advance what is known about effective and efficient policing practices. This report examines SPI’s accomplishments since its inception in 2009 and explores some of the major themes across SPI initiatives in both policing and policing research, including the following:

• Reductions in violent crime

• Improved crime analysis capabilities in police agencies

• Evolution of research partnerships with SPI sites

• Collaborative partnerships with agencies, organizations, and community stakeholders

• Integration of technology into policing

• Using data from a large national survey of online Australians, we examined the presence of risk and protective factors for cognitive and behavioural radicalisation among individuals who participated in an anti-authority protest since early 2020.

• Anti-authority protesters exhibited more risk factors and fewer protective factors for cognitive and behavioural radicalisation than other respondents, including people who had protested in support of other issues or movements. They were also more likely to justify violence in support of their cause and willing to support or participate in violent or unlawful behaviour on behalf of their group.

• These findings show that people who participated in anti-authority protests were more vulnerable to radicalisation compared with other protestors and non-protestors. The results have implications for responding to protest movements that promote anti-government sentiment, that spread disinformation and that are exploited by malicious actors.

The violent and contested overpolicing of LGBTQI+ communities at Sydney’s Gay and Lesbian Mardi Gras has a long and visible history which has been amplified through intensified drug policing over the last two decades. This article scrutinises police practices during Sydney WorldPride events in February and March 2023, which included Mardi Gras events. It draws on a unique data set drawn from the NSW Police Force and an independent legal observer initiative, ‘Fair Play’, that provided support for policed people at WorldPride. We ask: What do police practices tell us about the exercise of police power over LGBTQI+ people at WorldPride? Our study found intensive and aggressive high-visibility policing characterised by invasive questioning and drug detection dog patrols, and humiliating and potentially unlawful searches. The impacts illustrate how policing criminalises and gatekeeps belonging to sexual and gender-diverse communities.

Recent years have seen numerous books about the looming threat posed to Western society by biological and chemical terrorism, by narcoterrorists, and by the unpredictable leaders of rogue nations. Some of these works have been alarmist. Some have been sensible and measured. But none has been by Loch Johnson.

Johnson, author of the acclaimed Secret Agencies and "an experienced overseer of intelligence" (Foreign Affairs), here examines the present state and future challenges of American strategic intelligence. Written in his trademark style--dubbed "highly readable" by Publishers Weekly--and drawing on dozens of personal interviews and contacts, Johnson takes advantage of his insider access to explore how America today aspires to achieve nothing less than "global transparency," ferreting out information on potential dangers in every corner of the world.

And yet the American security establishment, for all its formidable resources, technology, and networks, currently remains a loose federation of individual fortresses, rather than a well integrated "community" of agencies working together to provide the President with accurate information on foreign threats and opportunities. Intelligence failure, like the misidentified Chinese embassy in Belgrade accidentally bombed by a NATO pilot, is the inevitable outcome when the nation's thirteen secret agencies steadfastly resist the need for central coordination.

Ranging widely and boldly over such controversial topics as the intelligence role of the United Nations (which Johnson believes should be expanded) and whether assassination should be a part of America's foreign policy (an option he rejects for fear that the U.S. would then be cast not only as global policeman but also as global godfather), Loch K. Johnson here maps out a critical and prescriptive vision of the future of American intelligence.

Recently, a wall was built in eastern Germany. Made of steel and cement blocks, topped with razor barbed wire, and reinforced with video monitors and movement sensors, this wall was not put up to protect a prison or a military base, but rather to guard a three-day meeting of the finance ministers of the Group of Eight (G8). The wall manifested a level of security that is increasingly commonplace at meetings regarding the global economy. The authors of Shutting Down the Streets have directly observed and participated in more than 20 mass actions against global in North America and Europe, beginning with the watershed 1999 WTO meetings in Seattle and including the 2007 G8 protests in Heiligendamm. Shutting Down the Streets is the first book to conceptualize the social control of dissent in the era of alter globalization. Based on direct observation of more than 20 global summits, the book demonstrates that social control is not only global, but also preemptive, and that it relegates dissent to the realm of criminality. The charge is insurrection, but the accused have no weapons. The authors document in detail how social control forecloses the spaces through which social movements nurture the development of dissent and effect disruptive challenges.

Mónica waits in the Anti-Venereal Medical Service of the Zona Galactica, the legal, state-run brothel where she works in Tuxtla Gutiérrez, Mexico. Surrounded by other sex workers, she clutches the Sanitary Control Cards that deem her registered with the city, disease-free, and able to work. On the other side of the world, Min stands singing karaoke with one of her regular clients, warily eyeing the door lest a raid by the anti-trafficking Public Security Bureau disrupt their evening by placing one or both of them in jail.

Whether in Mexico or China, sex work-related public policy varies considerably from one community to the next. A range of policies dictate what is permissible, many of them intending to keep sex workers themselves healthy and free from harm. Yet often, policies with particular goals end up having completely different consequences.

Policing Pleasure examines cross-cultural public policies related to sex work, bringing together ethnographic studies from around the world—from South Africa to India—to offer a nuanced critique of national and municipal approaches to regulating sex work. Contributors offer new theoretical and methodological perspectives that move beyond already well-established debates between “abolitionists” and “sex workers’ rights advocates” to document both the intention of public policies on sex work and their actual impact upon those who sell sex, those who buy sex, and public health more generally.

In its steady march across the United States, methamphetamine has become, to quote former Attorney General Alberto Gonzales, “the most dangerous drug in America.” As a result, there has been a concerted effort at the local level to root out the methamphetamine problem by identifying the people at its source—those known or suspected to be involved with methamphetamine. Government-sponsored anti-methamphetamine legislation has enhanced these local efforts, formally and informally encouraging rural residents to identify meth offenders in their communities.
Policing Methamphetamine shows what happens in everyday life—and to everyday life—when methamphetamine becomes an object of collective concern. Drawing on interviews with users, police officers, judges, and parents and friends of addicts in one West Virginia town, William Garriott finds that this overriding effort to confront the problem changed the character of the community as well as the role of law in creating and maintaining social order. Ultimately, this work addresses the impact of methamphetamine and, more generally, the war on drugs, on everyday life in the United States.

Many American communities are wrestling with how to reform their approach to public safety in the wake of police killings, particularly of Black men. There are many ideas for what the right reforms might be, ranging from minor policy tweaks to wholesale replacement of departments. To help communities as they sort through these ideas, we review real experiences with policing reform, highlighting wherever possible the best scientific evidence on the subject.

The Philadelphia Police Department began distributing 435 mobile smartphones to officers in police districts 22, 24, and 25 in February 2021. At the same time PPD established Crime Information Centers (CICs) to facilitate analysis and information sharing. We compared changes in police-related outcomes in districts 22, 24, and 25 with six districts (12, 14, 15, 19, 35, 39) that received no phones and had similar levels of serious crime. The smartphones provided officers with improved access to information and a convenient technology to receive requests for intelligence crucial to investigations, report street-level intelligence, and communicate directly with members of the community. Mobile phones/CICs have public safety benefits • An increase in the violent crime clearance rate from 24% to 30% • An increase in the likelihood that a stop resulted in an arrest — from 10% to 28% — suggesting more surgical policing, without increasing the number of stops conducted Mobile phones substantially ease regular PPD officers’ tasks • Greatly increased the amount and variety of evidence collected – Weekly uploads increased 40% after at least one SIG detective received a phone • Facilitated 311 reports to address physical disorder in districts • Made officers more willing and able to create intelligence reports • Enhanced basic communication between police and community members through calls and text messages, including direct contact about the location of illegal firearms • Can improve the completeness and timeliness of NCIC/PCIC checks, patrol logs, and court notices PPD has more to gain from mobile IT and CICs • More incentives are needed to promote smartphone use among officers. A few officers in each of the pilot districts were more active users of the smartphones – 5/7 squads use the phones a lot, others were infrequent users  – 3 officers submitted half of the 311 requests – 86% of officers submitted no intelligence reports at all – Usage has essentially ended in District 22 • Regular use of phones among officers could support mission-directed patrol – Monitoring the time spent in mission areas – Documenting mission-related business checks and home visits – Promote intelligence reports in mission areas • PPD could encourage additional phone usage – Encourage officers to share information and give feedback on how their intel reports and 311 reports are solving community problems – Emphasize phone usage in CompStat by tracking key metrics ∗ Time spent in strategic areas ∗ Number of leads connected to shootings or priority incidents ∗ Volume of direct calls/messages from community leading to crime clearances – Establish a clear policy on expected phone use, monitor use, and provide feedback to command staff and officers on the successful uses of technology

This evaluation suggests “the current GVI implementation in Philadelphia has been associated with significant reductions in group member involved firearm violence. The continued effectiveness of the implementation will likely depend on a range of factors, including necessary adjustments to evolving group activity and firearm violence.” Between January 2020 and May 2022, at least 1,147 Group Member-Involved shootings have occurred in Philadelphia. Approximately one out of every five of these shootings results in a death (23.1%). The current implementation of Group Violence Intervention (GVI) in Philadelphia has produced significant reductions in Group Member-Involved (GMI) firearm violence at the group-unit level during the study period, January 2020 to May 2022. It has also produced significant reductions in GMI firearm violence at the census tract-level during the study period. Importantly, due to COVID-19-related restrictions on public gatherings, the current GVI implementation in Philadelphia departed from the usual call-in meeting model. Instead, Mobile CallIn Team (MCIT) custom notification visits provided the primary means of GVI implementation. Given the results indicating a reduction in firearm violence, a GVI implementation through MCIT custom notification visits appears to maintain the effectiveness of GVI. Post-Treatment relative to Pre-Treatment, a group-unit, on average, experienced a significant 38.6% reduction in shootings per week. Notably, receiving 2 doses of treatment relative to 0 doses of treatment produced a significant 50.3% reduction in shootings per week for a group-unit. A census tract experienced a non-significant 25.1% reduction (p=0.07) in GMI shootings per week, Post-Treatment relative to Pre-Treatment. Importantly, however, where a census tract received 4 or more doses relative to 0 doses (Pre-Treatment), there was a significant 44.4% reduction (p=0.03) in GMI shootings per week. The effects of GVI on individual outcomes such as victimization and offending merit further research. A longer study period in prospective research will provide an opportunity to more precisely detect the effect of GVI on individual behavior and victimization risk. Enforcement actions were associated with a reduction in GMI shootings. Once it was subject to an enforcement action, a group experienced a significant 42.8% reduction (p=0.04) in shootings. Future research should identify the particular levers in an enforcement action that are most effective. This Evaluation conducted qualitative research to inform the quantitative findings. The qualitative research components were the following: (1) informal telephone conversations with GVI recipients; (2) surveys given to Philadelphia Police Department (PPD) officers involved in MCIT custom notifications; and (3) informal surveys distributed at two Philadelphia Roadmap for Safer Communities community meetings.

ShotSpotter is an acoustic gunfire detection technology utilized by police departments in over 150 cities world-wide with the intention of rapidly dispatching police officers to violent crime scenes in an effort to reduce gun violence. In Chicago, this amounts to approximately 70 instances per-day whereby officers are immediately dispatched to potential instances of gunfire. However, this allocation diverts police resources away from confirmed reports of 911 emergencies, creating delays in rapid response—a critical component of policing with health and safety implications. In this paper, we utilize variation in timing from ShotSpotter rollouts across Chicago police districts from 2016-2022 to estimate the causal effects of ShotSpotter on 911 emergency response times that are designated as Priority 1 (immediate dispatch). Using comprehensive 911 dispatch data from the Chicago Police Department, we find that ShotSpotter implementation causes police officers to be dispatched one-minute slower (23% increase) and arrive on-scene nearly two-minutes later (13% increase). Moreover, these effects are driven by periods with fewer police on-duty and times of day with larger numbers of ShotSpotter-related dispatches. Consequently, when responding to emergency calls, police officers’ success rate in arresting perpetrators decreases by approximately 9%, with notably large decreases in arrests for domestic battery (14%).

Following the unfortunate rise in the number of law enforcement officers killed in the USA between 2010 and 2011, the Bureau of Justice Assistance and Office of Community Oriented Policing Services created the national Officer Safety and Wellness (OSW) group to identify and support efforts to improve officer safety (Stephens et al., 2012). One of the more notable observations from the OSW group was that little is known about officerinvolved vehicle collisions despite these events often being the leading cause of officer fatalities in the USA on an annual basis (Stephens et al., 2013)[ 1 ]. This issue has largely been ignored by the research community and, as a result, there is virtually no empirical knowledge concerning the prevalence of vehicle collisions, the injury, and fatality outcomes of these events, the characteristics of these collisions, or the characteristics of individuals involved in such incidents. The impact of this empirical gap is a lack of knowledge for developing policy, practice, and training aimed at reducing injuries and fatalities resulting from vehicle collisions. The present study partially addresses this gap in the literature by examining more than 35,000 vehicle collisions involving officers in the State of California between 2000 and 2009. The analysis examines the outcomes of these events and the characteristics of the collisions and offices involved.

In the realm of public safety, Members of the RCMP play a vital and unique role, bearing the responsibility of upholding the law, protecting communities, and ensuring the well-being of Canadians, through municipal, provincial, and federal policing. Too often, they do so at risk of their own mental health and well-being. By choosing a life dedicated to the service of others through a career in public safety, they also accept the challenges and adversities inherent to their unique line of duty. Members are confronted daily with a myriad of stressors, risks, and emotionally taxing situations unique to their career which invariably take a toll on their psychological well-being. The very nature of their profession exposes them to violence, trauma, high-pressure situations, and a relentless demand for vigilance. This is compounded by organizational and operational stressors, mental health stigmatization, and a lack of comprehensive and accessible mental health services and supports. Over time, these factors have been shown to accumulate and lead to an array of mental health challenges, including posttraumatic stress disorder (PTSD), depression, anxiety, and a heightened risk of suicidal behavior. Understanding the mental health challenges faced by Members is a crucial step toward caring for Members and enhancing the overall effectiveness and sustainability of the RCMP. By recognizing and addressing these challenges, we can work towards more resilient, healthier, and better equipped Members who can continue to serve and protect Canadian communities safely and effectively. The National Police Federation (NPF) has demonstrated a strong commitment to supporting the mental health and wellbeing of Members of the RCMP. Recognizing the unique challenges and stressors faced by our Members, the NPF has actively engaged in partnerships to research and address mental health issues within the RCMP. Most recently, the NPF in partnership with the University of Regina and the Canadian Institute for Public Safety Research and Treatment (CIPSRT), funded a survey of serving Members across Canada. The NPF would like to thank all Members who took the significant time and commitment to participate in this survey. Some of the questions were potentially traumatic and tough, but by providing their voice, Members are helping make a difference for current and future Members.
