Importance  The root causes of violent crime in Black urban neighborhoods are structural, including residential racial segregation and concentrated poverty. Previous work suggests that simple and scalable place-based environmental interventions can overcome the legacies of neighborhood disinvestment and have implications for health broadly and crime specifically. Objective  To assess whether structural repairs to the homes of low-income owners are associated with a reduction in nearby crime. Design, Setting, and Participants  This cross-sectional study using difference-in-differences analysis included data from the City of Philadelphia Basic Systems Repair Program (BSRP) from January 1, 2006, through April 30, 2013. The unit of analysis was block faces (single street segments between 2 consecutive intersecting streets) with or without homes that received the BSRP intervention. The blocks of homes that received BSRP services were compared with the blocks of eligible homes that were still on the waiting list. Data were analyzed from December 1, 2019, to February 28, 2021. Exposures  The BSRP intervention includes a grant of up to $20 000 provided to low-income owners for structural repairs to electrical, plumbing, heating, and roofing damage. Eligible homeowners must meet income guidelines, which are set by the US Department of Housing and Urban Development and vary yearly. Main Outcomes and Measures  The main outcome was police-reported crime across 7 major categories of violent and nonviolent crimes (homicide, assault, burglary, theft, robbery, disorderly conduct, and public drunkenness). Results  A total of 13 632 houses on 6732 block faces received the BSRP intervention. Owners of these homes had a mean (range) age of 56.5 (18-98) years, were predominantly Black (10 952 [78.6%]) or Latino (1658 [11.9%]) individuals, and had a mean monthly income of $993. These census tracts compared with those without BSRP intervention had a substantially larger Black population (49.5% vs 12.2%; |D| = 0.406) and higher unemployment rate (17.3% vs 9.3%; |D| = 0.357). The main regression analysis demonstrated that the addition to a block face of a property that received a BSRP intervention was associated with a 21.9% decrease in the expected count of total crime (incidence rate ratio [IRR], 0.78; 95% CI, 0.76-0.80; P<.001), 19.0% decrease in assault (IRR, 0.81; 95% CI, 0.79-0.84; P<.001), 22.6% decrease in robbery (IRR, 0.77; 95% CI, 0.75-0.80; P<.001), and 21.9% decrease in homicide (IRR, 0.78; 95% CI, 0.71-0.86; P<.001). When restricting the analysis to blocks with properties that had ever received a BSRP intervention, a total crime reduction of 25.4% was observed for each additional property (IRR, 0.75; 95% CI, 0.73-0.77; P<.001). A significant dose-dependent decrease in total crime was found such that the magnitude of association increased with higher numbers of homes participating in the BSRP on a block. Conclusions and Relevance  This study found that the BSRP intervention was associated with a modest but significant reduction in crime. These findings suggest that intentional and targeted financial investment in structural, scalable, and sustainable place-based interventions in neighborhoods that are still experiencing the lasting consequences of structural racism and segregation is a vital step toward achieving health equity.

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.

Police traffic stops for minor violations have gained considerable attention among scholars and advocates, and some research has found evidence of racial disparities in who is stopped for certain traffic violations. Recognizing the potential for racial disparities and other issues, various jurisdictions have sought to limit traffic stops. On January 14, 2022, the Seattle (Washington) Police Chief Adrian Diaz stated that the Seattle Police Department (SPD) would discontinue stopping individuals for various traffic violations. While these policies were enacted in part to reduce racial disparities and other outcomes that may flow from such stops, some have argued that limiting stops may lead to increased crime rates and traffic accidents due to the reduced investigatory reach of law enforcement. Another possibility is that some crimes, which may have been discovered during a routine traffic stop, could go undetected after a jurisdiction implements a traffic stop restriction policy. The current study explored whether the Seattle traffic stop restriction policy resulted in a decrease in the number of driving under the influence (DUI) and drug crime incidents. The results did not show statistically or substantively significant declines in the number of DUI or drug crime incidents in Seattle after the implementation of the traffic stop restriction policy. Replication is recommended before strong conclusions are drawn.

This study, co-produced by the Drug Enforcement and Policy Center and the York College of Pennsylvania School of Behavioral Sciences and Education Criminology and Criminal Justice Department, evaluated the impact of York City’s Group Violence Initiative on firearm incidents, violent crime incidents, and recidivism. The results of the primary model did not support the hypothesis that the intervention reduced firearm incidents in York City. The results of the primary model also did not support the hypothesis that the intervention reduced violent crime incidents in York City. However, potential violations of assumptions for time series designs and inconsistent regression results did not support strong conclusions regarding the effect of the intervention on the rate of firearm incidents and violent crime incidents. The recidivism rate for individuals involved in call-in meetings was 83.33%. Data recording procedures and data quality meaningfully improved over the course of the project. These improvements allow York City to be well-positioned for future evaluation projects and data-driven policy shifts.

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%).

In times of crisis, people call 911 to receive emergency assistance. For decades, the 911 system has operated using legacy infrastructure (i.e., telephone calls through the public switched telephone network). In the 2000s, local governments and public safety officials identified the need to keep pace with emerging communications technologies and communication formats that consumers use in daily life (e.g., texts, videos, photos). As such, some public safety answering points (PSAPS, also known as 911 centers) are upgrading their infrastructure to Internet Protocol (IP)-based systems—referred to as Next Generation 911 (NG911). When fully transitioned, NG911 is anticipated to enhance emergency response service, making it easier for the public to report emergency needs and for first responders to receive rich information. This includes multimedia transmissions—such as text messages, streaming video, and photos—directly from the public to PSAPs, which can enhance situational awareness for 911 telecommunicators in dispatching emergency response. Additionally, NG911 allows for interoperability with other PSAPs so that calls can be transferred to other centers for response—for example, in the event of call overload during a disaster—and also for interconnection with the First Responder Network Authority (FirstNet) to seamlessly transfer data directly from PSAPs to first responders in the field.

When Minneapolis police officers killed George Floyd in May 2020, the nearby city of Brooklyn Park began urgent work, including convening listening sessions and tasking city commissions with creating a work plan to improve the Brooklyn Park Police Department.

In December 2020, the City of Brooklyn Park hired Wilder Research to uncover the root causes of violence in Brooklyn Park, understand community perceptions of the Brooklyn Park Police Department, create research-driven recommendations to improve community safety, and develop a tool to assess and improve the Brooklyn Park Police Department’s performance. Wilder Research reviewed existing research on community safety and policing, analyzed Brooklyn Park specific community survey data related to the root causes of violence, and conducted interviews with residents and employees of Brooklyn Park.

High-level findings:

• There are risks of violence when people are not economically secure or connected to their community.

• There are disparities in Brooklyn Park that likely contribute to violence and disorder.

• Improving traditional policing may not improve safety.

• Brooklyn Park Police Department policies and interviewee themes support that procedural justice is a key strength; even so, some BPPD policies and Minnesota laws conflict with best practices.

Recommendations:

• Focus on prevention. To improve safety, the city should address inequities, and ensure that the social conditions where safety thrives are equally distributed across races and places in Brooklyn Park.

• Improve interventions. The city should explore using community-based mental health and substance use responses, school-based safety workers, and other efforts to reimagine police responsibilities. The city should also partner with community stakeholders to expand focused deterrence initiatives, and interventions including treatment and restorative justice.

• Assess BPPD for improvements. We developed a scorecard to measure BPPD performance. We recommend the city, BPPD, and community members impacted by systemic marginalization and police contact partner to assess and recommend changes to BPPD.

Background

Two legal doctrines in Minnesota – aiding and abetting liability and felony murder – converge to allow anyone who contributes to a felony to be charged with and punished for murder if a death occurs during the course of the felony, even if that person did not cause death, cause any injury to the deceased, nor intend for anyone to die. Aiding and abetting liability means that people are criminally liable for the crime of another if the first person aids, advises, counsels, or conspires to commit that crime (Minnesota Statutes 2021, section 609.05). Under the doctrine of felony murder, anyone who kills another during the course of committing a felony is liable for murder, even if they did not intend for death to result (Minnesota Statutes 2021, section 609.185 and 609.195). Taken together, this means that people in Minnesota can be punished for murder when they did not kill, injure, or even intend harm, so long as they contribute to a felony, and a death results during the course of the felony (called “aiding and abetting felony murder”).

In June 2021, the Minnesota Legislature established the Task Force on Aiding and Abetting Felony Murder (Task Force) (Laws of Minnesota 2021, 1st Spec. Sess. chapter 11, article 2, section 53) in order to understand any benefits and unintended consequences of Minnesota’s aiding and abetting felony murder doctrine. The Task Force organized into three subcommittees. One to collect and analyze data about charges, convictions, and sentences under the doctrine, one to review statutes and case law across the 50 states, and one to invite input from victims’ loved ones and those impacted by the current doctrine. In November 2021, the Task Force hired Wilder Research to review literature, aid in data analysis, and write the report to the legislature. This report summarizes this task force’s work, findings, and recommendations.

Key findings:

Studies on deterrence, incarceration’s lack of impact on re-offense, and adolescent brain development raise concerns with this doctrine.

To contextualize the issue, Wilder Research staff reviewed research on deterrence, incarceration’s impact on reoffense, and adolescent brain development. Decades of studies show that the threat of punishment alone does not deter crime (Rocker, 2021), that incarceration compared to non-custodial sanctions has no impact on reoffense or tends to increase the risk that the person who experiences incarceration will reoffend (Petrich et al., 2021), and that those in their teens through mid-20s are in a unique stage of brain development that make them less capable to assess risk and consequences, and more apt to be motivated by emotion and peer pressure than those older (Dobscha, 2019; Johnson et al., 2009). With this, Task Force members were concerned that Minnesota’s aiding and abetting felony murder doctrine does not deter behavior, does not reduce the risk of re-offense, and may especially harm those in their mid-20s and younger who are held liable under this doctrine.

Young people, people charged by Hennepin County, Black people, and males with little to no prior criminal history make up the largest groups of people charged, convicted, and sentenced under this doctrine.

From 2010 through 2019, there have been 130 people charged with aiding and abetting felony murder across Minnesota, and 84 people convicted of aiding and abetting felony murder as the most severe conviction. The Task Force analyzed patterns in charges, convictions, and sentences, and found that people 25 years and younger, people in Hennepin County, Black people, and people with little to no criminal history are those most frequently impacted by aiding and abetting felony murder liability. The Task Force was concerned with geographic, race, and age disparities that have happened under this doctrine.

Recent national trends are to limit aiding and abetting felony murder liability, not expand it.

The Task Force reviewed felony murder and aiding and abetting liability statutes from the 50 states, and also seminal state appellate or state Supreme Court cases relevant to aiding and abetting felony murder liability in Minnesota and around the country. The Task Force also heard presentations about whether other common law countries apply felony murder liability. The United States is the only common law country that has not yet abolished felony murder liability generally, and past decades have seen U.S. state legislatures and review courts abolish and otherwise limit aiding and abetting felony murder liability.

Victims and those convicted under the doctrine support limiting aiding and abetting felony murder liability, with avenues for retroactive relief.

The Task Force invited connection with victims’ families through contacting 37 victim/survivor organizations, and heard from victims’ families through the Minnesota Alliance on Crime (MAC). MAC is a statewide coalition of victim/survivor advocate organizations; 75% of their membership are victim-witness programs in county attorney offices, and the rest are community-based organizations. The Task Force also heard from 10 people convicted under this doctrine, and one person who rejected a deal to plead guilty to aiding and abetting felony murder. MAC expressed support for retroactive reform such that aiders and abettors of an underlying felony are not punished for the homicidal acts of another, and said that such retroactive reforms would be supported by the vast majority of its members. Impacted individuals expressed accountability for their role in the underlying felony and shared many difficulties stemming from being held criminally liable for the homicidal acts of another. Those impacted individuals who spoke on the subject strongly supported retroactive reforms to limit aiding and abetting felony murder liability.

The adverse consequences of Minnesota’s aiding and abetting felony murder doctrine outweigh its benefits.

After analyzing the above key findings, the Task Force agreed that the adverse consequences of the current aiding and abetting felony murder doctrine outweigh its benefits.

On May 25, 2020, a Black Minneapolis resident, George Floyd, was murdered by a Minneapolis police officer, Derek Chauvin. The officer kneeled on Mr. Floyd’s neck for over nine minutes, while two other Minneapolis police officers helped pin him down for a portion of that time. Another police officer prevented several bystanders from intervening as they watched Mr. Floyd die.

Vigils and peaceful protesting began immediately after the murder, at the scene (38th Street and Chicago Avenue) and in other locations, and continued through June 7, 2020. Civil unrest, including violence and destructive behavior, started within 24 hours at the scene and in other parts of Minneapolis and Saint Paul, in the state of Minnesota, around the U.S., and internationally. Looting and arson were widespread, and local police and emergency responders could not respond to many calls for help— either because they couldn't safely access the area or were too overwhelmed. Minnesota State Law Enforcement Agencies, including the Minnesota State Patrol, Minnesota Department of Natural Resources Law Enforcement Division, and other agencies, along with the Minnesota National Guard were called upon by the governor to provide services outside of their specific jurisdiction and training. Although these state-level entities were better equipped to respond to this particular crisis than local jurisdictions due to their training, equipment, and number of officers, they did not have experience responding to a large-scale civil disturbance and extended period of civil unrest such as what occurred in Minneapolis after Mr. Floyd’s murder.

External review commissioned

In February 2021, the Minnesota Department of Public Safety (DPS) contracted with Wilder Research to conduct an external review of the state’s response to civil unrest that occurred May 26-June 7, 2020, following the murder of George Floyd. DPS requested that the review:

• Objectively evaluate what the state did well and did not do well.

• Identify actions and options that may have produced different, or possibly better, outcomes.

• Provide recommendations to the Commissioner of Public Safety to assist state and local governmental units, including cities and counties, in responding effectively to potential periods of regional or statewide civil unrest in the future.

‘The Wicked and the Redeemable’ reveals that:

• Despite representing nine percent of the nearly six million people convicted of a criminal offence between 2000 and 2021 prolific offenders receive over half of all convictions.

• The Crown Prosecution Service is taking far longer to charge suspects than ever before. It now takes an average of nearly 44 days compared to 14 days seven years ago. These delays are putting vulnerable victims at risk of considerable harm as a result of wholly unnecessary bureaucracy.

• The number of cases that have been outstanding for more than 6 months (the expected standard) has quadrupled in the last four years to 30,384 cases. This is part of the biggest ever Crown Court backlog in history (with 64,709 cases now outstanding – double the number four years ago).

• Despite already having more than 45 previous convictions, ‘Hyper-Prolific Offenders’ are sent to prison on less than half of all occasions (47.3%) on conviction for an indictable or either-way offence. For ‘Prolific Offenders’, those with 16 previous convictions or more, the number falls to less than a quarter being sent to prison on conviction (24.4%) for an indictable or either-way offence.

Executive summary The primary goal of this project was to explore how gun violence prevention work impacts individuals considered at high risk of being directly impacted by gun violence. The current study aimed to elevate the voices of gun violence prevention program participants and impacted communities who can best attest to the influence and power of the message and services received. Gun Violence Prevention Models and Projects The Group Violence Intervention (GVI) model used in this work is a focused-deterrence strategy that targets groups of people at high risk of gun violence. GVI is facilitated by law enforcement agencies that identify individuals who are associated with or members of groups responsible for shootings. These individuals receive an anti-violence message from law enforcement agencies partnered with community representatives and social services providers. In New Haven, CT, Project Safe Neighborhoods (2002) and Project Longevity (2012) are current initiatives modeled after the GVI strategy. Cure Violence is a public health approach to address violence as a disease to be treated by violence interrupters in the community that mediate conflicts. One prominent community-based organization that modeled the Cure Violence Approach in New Haven, CT is Connecticut Violence Intervention Program (CTVIP). The Community Perspective Numerous evaluations across the nation highlight the success of the GVI and Cure Violence programs. However, many of these policy evaluations do not include the perspectives of the people closest to the problem and they also fall short of addressing the complexities and concurrent, environmental factors underlying participation within GVI initiatives. To this end, the current study explored how individuals at high risk of gun violence benefit from gun violence prevention services whether simultaneously participating in a GVI strategy or not. The current study emphasized why the field of gun violence prevention policy needs studies that are designed to elucidate the critical components of such programs from the community perspective, with results that show that the theory of change accurately represents the impact mechanisms at work on the ground. This project, therefore, proposed an exploratory, qualitative study of initiatives to address gun violence in New Haven, CT. The goal was to explore how gun violence prevention work impacts individuals considered at high risk of being perpetrators or victims of gun violence.

Objectives This paper estimates the effect of changes in street lighting at night on levels of crime at street-level. Analyses investigate spatial and temporal displacement of crime into adjacent streets. Methods Offense data (burglaries, robberies, theft of and theft from vehicles, and violent crime) were obtained from Thames Valley Police, UK. Street lighting data (switching lights off at midnight, dimming, and white light) were obtained from local authorities. Monthly counts of crime at street-level were analyzed using a conditional fixed-effects Poisson regression model, adjusting for seasonal and temporal variation. Two sets of models analyzed: (1) changes in night-time crimes adjusting for changes in day-time crimes and (2) changes in crimes at all times of the day. </jats:sec><jats:sec> Results Switching lights off at midnight was strongly associated with a reduction in night-time theft from vehicles relative to daytime (rate ratio RR 0.56; 0.41–0.78). Adjusted for changes in daytime, night-time theft from vehicles increased (RR 1.55; 1.14–2.11) in adjacent roads where street lighting remained unchanged.  Conclusion Theft from vehicle offenses reduced in streets where street lighting was switched off at midnight but may have been displaced to better-lit adjacent streets. Relative to daytime, night-time theft from vehicle offenses reduced in streets with dimming while theft from vehicles at all times of the day increased, thus suggesting temporal displacement. These findings suggest that the absence of street lighting may prevent theft from vehicles, but there is a danger of offenses being temporally or spatially displaced.

The U.S. Department of Homeland Security requires research and development to assess methods for reducing the propensity and loss of life from attacks on soft targets and crowded places (ST-CPs). Researchers conducted a comprehensive landscape assessment of the threat to ST-CPs and corresponding security measures to identify needs for improvement, and they recommended research and investment priorities for addressing those needs. 

The number of attack plots is broadly aligned with regional population counts, except that there were more plots in New York City and Washington, D.C. The most-common motivations for ST-CP attacks have been personal, followed by terrorist and racial and ethnic extremist motivations. The ST-CP locations targeted have been diverse and often directly accessible. Education and private buildings (workplaces) are the most–frequently targeted types of ST-CPs. In general, locations in which a would-be attacker had ready access to a dense crowd on scene had the highest average lethality (close to six deaths, on average, as compared with fewer than three when there was not a dense crowd present). Not surprisingly, locations that typically have large crowds without controlled entries, such as houses of worship, shopping malls, restaurants, bars, and nightclubs, had the highest average lethality.

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.
