There is increasing pressure for the juvenile criminal legal system to address trauma; this is in response to advances in the science of trauma and adversity, evidence from interventions showing promising outcomes for juveniles coping with trauma, and development of systemic frameworks for providing trauma-informed care. This review details how exposure to potentially traumatic events can create primary, secondary, and tertiary effects that are relevant to how the criminal legal system engages with juveniles coping with trauma. Associations that could be dismissed on methodological challenges can no longer be ignored as an increasingly sophisticated body of prospective studies replicate previous cross-sectional and retrospective studies, which found a higher prevalence of trauma among system-involved juveniles and show that exposure to potentially traumatic events and trauma symptoms play causal roles in engaging in behaviors that can be classified as criminal offending. Additionally, several examples are used to illustrate how racialized exposure to systemic trauma across generations underlies racialized disparities in persistent criminal offending—over exposure to potentially traumatic events and underexposure to coping resources. A broad range of developmental and criminological research is drawn upon to provide frameworks for implementing trauma-informed care as a systemic intervention aimed at minimizing retraumatization and using every interaction that juveniles have with the criminal legal system to contribute to recovery and prevent recidivism.

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.

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.

Given news reporting in recent years, many readers are likely familiar with research which finds that, conditional on an encounter, police officers are more likely to enforce a law, conduct a search, or use force when a civilian belongs to a racial minority group. In other words, once they are stopped, minorities are more likely to face some police action. However, what research has yet to show is whether minorities are stopped more in the first place.

This new paper addresses the issue of minority status and the likelihood of police encounters by reviewing driving data from Lyft records in Florida from August 2017 to August 2020, totaling over 40 billion observations. These data allow the authors to explore whether minority drivers, because they are minorities, are more likely to be stopped and to be issued a citation. To examine this question, the authors focus on citations for speeding.

Purpose –—The purpose of this paper is to update the assessment of national data on law enforcement worker suicide based on the National Occupational Mortality Surveillance database (NOMS, Centers for Disease Control and Prevention). Design/methodology/approach –—Death certificate data for 4,441,814 decedents, age 18–90 who died in one of the 26 reporting states were the source of NOMS data. Utilizing proportionate mortality ratios (PMRs), the ratio of suicides in law enforcement occupations in those who are 18– 90 years old with a designated usual occupation was calculated. Findings –—Findings indicate a significantly higher proportion of deaths from suicide for law enforcement officers (PMR = 154, 95% CI = 147–162), compared to all the US decedents in the study population who were employed during their lifetime. Law enforcement personnel are 54% more likely to die of suicide than all decedents with a usual occupation. PMRs were highest for African-Americans, Hispanic males and for females. PMRs were similar for detectives, corrections officers and all law enforcement jobs, when not stratified by race, ethnicity and sex. Research limitations/implications –—Bias may arise because a PMR can be affected by disproportionate increased or decreased mortality from causes of death other than suicide. Practical implications –—A better understanding of the scope of law enforcement suicide can inform policy focused on the planning and initiation of prevention programs. Originality/value –—The use of a national database to study law enforcement worker suicide adds to other information available on law enforcement worker suicide in specific geographic areas. The discussion on prevention in this paper presents ideas for policy

We use data on police-involved deaths to estimate how the risk of being killed by police use of force in the United States varies across social groups. We estimate the lifetime and age-specific risks of being killed by police by race and sex. We also provide estimates of the proportion of all deaths accounted for by police use of force. We find that African American men and women, American Indian/Alaska Native men and women, and Latino men face higher lifetime risk of being killed by police than do their white peers. We find that Latina women and Asian/Pacific Islander men and women face lower risk of being killed by police than do their white peers. Risk is highest for black men, who (at current levels of risk) face about a 1 in 1,000 chance of being killed by police over the life course. The average lifetime odds of being killed by police are about 1 in 2,000 for men and about 1 in 33,000 for women. Risk peaks between the ages of 20 y and 35 y for all groups. For young men of color, police use of force is among the leading causes of death.

In 2015, for the first time in nearly forty years, the rate of motor vehicle fatalities for Black Americans exceeded that of white Americans. By 2020, the gap in death rates stood at 34%, accounting for approximately 4,000 excess deaths between 2014 and 2020. This disproportionate increase occurred in nearly all states, in rural as well as urban areas, and was shared by drivers of all ages and genders. We consider a variety of potential explanations for the emerging race gap including race-specific changes in time spent driving, the circumstances of driving, the quality of medical care for crash victims, decreases in other types of mortality, changes in policing, and risky driving behaviors such as speeding, driving without a seat belt and driving while intoxicated. We can rule out many of these factors as important contributors to the race gap, but find evidence for two of them. The first is opportunity: Relative to white Americans, Black Americans are spending more time in vehicles than they have in the past. Changes in time spent driving, while modest, likely explain an important share of the emergent race gap. The second is a relative increase in drug use, manifested by a quadrupling of the rate of overdose deaths among Black Americans after 2014. Increased drug use appears to have resulted in a concomitant increase in fatal crashes involving drivers under the influence of drugs. Finally, we consider whether the emerging race gap is explained by the so-called "Ferguson effect," the idea that police officers have pulled back from enforcement activity in recent years. On the one hand, traffic stops

  made by police officers do appear to have declined after 2014. However, the decline in traffic stops does not appear to be race-specific and there is little evidence of a broad increase in risky driving behaviors like speeding and driving without a seat belt.
