A national analysis of trauma care proximity and firearm assault survival among U.S. police.

Past research on factors influencing firearm assault (FA) mortality have not focused on police officers who, compared to other U.S. workers and the general public, experience especially high rates of firearm victimization. This study focuses on this unique population of FA victims and examines the relationship between travel time to the nearest trauma care facility and the probability of survival among officers shot on duty. Combining data on trauma care center location and 7 years of data on U.S. police officers fatally or non-fatally assaulted with a firearm, we use logistic regression to model the probability of FA fatality among police by proximity of the FA to the nearest trauma care facility. We find that travel time to trauma care was not associated with reduced FA mortality among police from 2014 to 2020. FA mortality was significantly lower in 2020 than the six years prior.

Comparing 911 and emergency hotline calls for domestic violence in seven cities: What happened when people started staying home due to COVID-19?

Research Summary: We examine changes in help-seeking for domestic violence (DV) in seven U.S. cities during the COVID-19 pandemic. Using Bayesian structural time-series modeling with daily data to construct a synthetic counterfactual, we test whether calls to police and/or emergency hotlines varied in 2020 as people stayed home due to COVID-19. Across this sample, we estimate there were approximately 1030 more calls to police and 1671 more calls to emergency hotlines than would have occurred absent the pandemic. Policy Implications: Interagency data sharing and analysis holds great promise for better understanding localized trends in DV in real time. Research-practitioner partnerships can help DV coordinated community response teams (CCRTs) develop accessible and sustainable dashboards to visualize data and advance community transparency. As calls for drastic changes in policing are realized, prioritization of finite resources will become critical. Data-driven decision-making by CCRTs provides an opportunity to work within resource constraints without compromising the safety of DV victims.

Factors associated with police shooting mortality: A focus on race and a plea for more comprehensive data.

OBJECTIVES: To quantify nonfatal injurious police shootings of people and examine the factors associated with victim mortality. METHODS: We gathered victim-level data on fatal and nonfatal injurious police shootings from four states that have such information publicly available: Florida (2009-14), Colorado (2010-19), Texas (2015-19), and California (2016-19). For each state, we examined bivariate associations between mortality and race/ethnicity, gender, age, weapon, and access to trauma care. We also estimated logistic regression models predicting victim mortality in each state. RESULTS: Forty-five percent of these police shooting victims (N = 1,322) did not die. Black-white disparities were more pronounced in nonfatal injurious police shootings than in fatal police shootings. Overall, Black victims were less likely than white victims to die from their wound(s). Younger victims were less likely to die from their wound(s), as well as those who were unarmed. CONCLUSIONS: Racial and age disparities in police shootings are likely more pronounced than previous estimates suggest. POLICY IMPLICATIONS: Other states should strongly consider compiling data like that which is currently being gathered in California. Absent data on nonfatal injurious police shootings-which account for a large share of deadly force incidents-researchers and analysts must be cautious about comparing and/or ranking jurisdictions in terms of their police-involved fatality rates.

What does the public want police to do during pandemics? A national experiment.

Research Summary: We administered a survey experiment to a national sample of 1068 U.S. adults in April 2020 to determine the factors that shape support for various policing tactics in the midst of the COVID-19 pandemic. Respondents were sharply divided in their views about pandemic policing tactics and were least supportive of policies that might limit public access to officers or reduce crime deterrence. Information about the health risks to officers, but not to inmates, significantly increased support for "precautionary" policing, but not for "social distance" policing. The information effect was modest, but may be larger if the information came from official sources and/or was communicated on multiple occasions. Other factors that are associated with attitudes toward pandemic policing include perceptions of procedural justice, altruistic fear, racial resentment, and authoritarianism. Policy Implications: When considered together with other evidence, one clear takeaway from our study is that the public values police patrols and wants officers on call, even during pandemics. Another is that people who believe the police are procedurally just are more willing to trust officers in times of crisis and to empower them to enforce new laws, such as social distancing ordinances. Our results thus support continued procedural justice training for officers. A third takeaway is that agencies must proactively communicate with the public about the risks their officers face when responding to public health crises or natural disasters, in addition to how they propose to mitigate those risks. They must also be amenable to adjusting in response to community feedback.

On the challenges associated with the study of police use of deadly force in the United States: A response to Schwartz & Jahn.

In response to Gabriel Schwartz and Jaquelyn Jahn's descriptive study, "Mapping fatal police violence across U.S. metropolitan areas: Overall rates and racial/ethnic inequalities, 2013-2017," I provide three reflections. First, the framing of this issue is vitally important. Second, police-involved fatalities represent a nonrandom sample of all incidents involving police use of deadly force (i.e., physical force that causes or is likely to cause death), and unfortunately, we lack comprehensive data on use of deadly force that does not result in fatalities. Finally, to make sense of who is killed by the police, researchers must also identify who was exposed to the risk of being killed by the police.

Gun victimization in the line of duty: Fatal and nonfatal firearm assaults on police officers in the United States, 2014-2019.

Research Summary: Using open-source data from the Gun Violence Archive (GVA), we analyze national- and state-level trends in fatal and nonfatal firearm assaults of U.S. police officers from 2014 to 2019 (N = 1,467). Results show that (a) most firearm assaults are nonfatal, (b) there is no compelling evidence that the national rate of firearm assault on police has substantially increased during the last 6 years, and (c) there is substantial state-level variation in rates of firearm assault on police officers. Policy Implications: GVA has decided strengths relative to existing data sources on police victimization and danger in policing. We consider the promises and pitfalls of this and other open-source data sets in policing research and recommend that recent state-level improvements in use-of-force data collection be replicated and expanded to include data on violence against police.

The Las Vegas mass shooting: An analysis of blood component administration and blood bank donations.

BACKGROUND: The deadliest mass shooting in modern United States history occurred on October 1, 2017, in Las Vegas, killing 58 and overwhelming hospitals with more than 600 injured. The scope of the tragedy offers insight into medical demands, which may help guide preparedness for future mass shooting incidents. METHODS: Retrospective, deidentified, health care institution-provided data from all hospitals and blood banks providing care to Las Vegas shooting victims were gathered. Study authors independently reviewed all data and cross-referenced it for verification. Main outcomes and measures include the number of victims requiring hospital and intensive care admission, the amount and types of blood components transfused during the first 24 hours, and the amount of blood donated to local blood banks following the Las Vegas mass shooting. RESULTS: Two hundred twenty patients required hospital admission, 68 of them to critical care. Nearly 500 blood components were transfused during the first 24 hours in a red blood cell-to-plasma-to-platelet ratio of 1:0.54:0.81. Public citizens donated almost 800 units of blood immediately after the shooting; greater than 17% of this donated blood went unused. CONCLUSIONS: The amount of blood components transfused per patient admitted was similar in magnitude to other mass casualty events, and available blood supply met patient demand. The public call for blood donors was not necessary to meet immediate demand and led to resource waste. Preparation for future mass shooting incidents should include training the community in hemorrhage control, encouraging routine blood donation, and avoiding public calls for blood donation unless approved by local blood suppliers. LEVEL OF EVIDENCE: Therapeutic study, level V.

Police managers' self-control and support for organizational justice.

Recent policing research has identified a positive relationship between line-level officers' perceptions of organizational justice and their adherence to agency goals and job satisfaction. However, we have little understanding of the factors that are related to police managers' support for organizational justice when interacting with employees. We collected survey data from a sample of U.S. command-level officers (N = 211) who attended a training program in a southern state to address this gap in the literature. The anonymous survey was administered in-person to participating command-level police officers prior to their training program. Our multivariate regression analysis revealed that police managers who reported higher levels of self-control were more supportive of organizational justice (b = .26, p < .01). Additionally, police managers who reported higher quality relationships with their colleagues expressed greater support for organizational justice (b = .02, p = .02). Respondents' self-legitimacy was not significantly associated with their support for organizational justice. This study contributes to the organizational justice literature by presenting the first analysis that links police commanders' self-control to support for organizational justice within their management practices. The findings help pinpoint the types of individuals who may be best equipped to be fair police managers. (PsycINFO Database Record

The alleged "Ferguson Effect" and police willingness to engage in community partnership.

In response to increasing violent crime rates in several U.S. cities over the past year, some have pointed the finger of blame at de-policing, a result of the so-called "Ferguson Effect." Although the Ferguson Effect on crime rates remains an open question, there may also be a Ferguson Effect on other aspects of police officers' jobs, such as willingness to partner with community members. This study used data from a cross-sectional survey of 567 deputies at an agency in the southeastern U.S. to accomplish 2 objectives: (a) to determine whether the Ferguson Effect is associated with de-policing in the form of decreased willingness to engage in community partnership, and (b) to determine whether such an effect persists upon accounting for perceived organizational justice and self-legitimacy. Ordinary least squares (OLS) regression equations revealed that the Ferguson Effect (as operationalized by reduced motivation stemming from recent negative publicity) was associated with less willingness to engage in community partnership (b = -.10; 95% CI = -.16, -.05). However, upon accounting for organizational justice and self-legitimacy, the Ferguson Effect was rendered insignificant (b = .01; 95% CI = -.05, .07). The findings suggest that officers who have confidence in their authority or perceive their agency as fair are more willing to partner with the community to solve problems, regardless of the effects of negative publicity.
