Firearm Homicides by Police in the United States: Who is Shot and How Many Times?
Introduction
The U.S. has the highest rate of deadly police encounters in the developed world. Recent cases highlight that police shoot individual suspects several times. This study aimed to assess variation in rates of police firearm homicide and the number of gunshot wounds among those shot and killed by police.
Methods
National Violent Death Reporting System was analyzed in 2023/2024, using data from 2005 to 2020 to estimate rates of police homicide across populations. Negative binomial regression models were used to evaluate factors associated with a greater number of GSWs among those who died due to police firearm homicide.
Results
Across 46 states and 2.09 billion person-years, 6.4% of all firearm homicides were by police (n=5,241). A total of 79% of police victims were shot multiple times (mean=5.98 gunshot wounds), compared with 65% of civilian victims (mean=3.94 gunshot wounds). The rate of police firearm homicide per million person-years was highest for victims aged 25–44 years (5.23); males (4.91); Black (4.61), Hispanic (3.76), and American Indian/Alaska Native people (4.74); and residents of the West (4.65). Accounting for victim weapon use, those aged 35–44 years (IRR=1.13, 95% CI=1.03, 1.23), who were Black (IRR=1.10, 95% CI=1.02, 1.17), or outside of the Northeast (IRRs=1.19–1.34) were most likely to suffer from more gunshot wounds.
Conclusions
In firearm homicides, police cause more gunshot wounds per fatality than civilians. Those who are aged 25–44 years, who are Black, or who live outside of the Northeast are more likely to die from police firearm homicide and have more gunshot wounds per fatality.
期刊介绍:
The American Journal of Preventive Medicine is the official journal of the American College of Preventive Medicine and the Association for Prevention Teaching and Research. It publishes articles in the areas of prevention research, teaching, practice and policy. Original research is published on interventions aimed at the prevention of chronic and acute disease and the promotion of individual and community health.
Of particular emphasis are papers that address the primary and secondary prevention of important clinical, behavioral and public health issues such as injury and violence, infectious disease, women''s health, smoking, sedentary behaviors and physical activity, nutrition, diabetes, obesity, and substance use disorders. Papers also address educational initiatives aimed at improving the ability of health professionals to provide effective clinical prevention and public health services. Papers on health services research pertinent to prevention and public health are also published. The journal also publishes official policy statements from the two co-sponsoring organizations, review articles, media reviews, and editorials. Finally, the journal periodically publishes supplements and special theme issues devoted to areas of current interest to the prevention community.
