Objectives. In the U.S., state firearm ownership has been correlated with homicide rates. Over 90% of homicides of law enforcement officers (LEOs) are committed with firearms. This study examined the relationship between state firearm ownership rates and LEO occupational homicide rates. Methods. LEOs killed from 1996 – 2010 were obtained from a Federal Bureau of Investigation (FBI) database. Homicide rates per state were calculated as number of officers killed per number of LEOs per state, obtained from another FBI database. Mean household firearm ownership for each state came from the Behavioral Risk Factor Surveillance System. For regression analyses, violent crime rate, obtained from FBI data, and other covariates associated with LEO homicide rate were selected as control variables. Results. In negative binomial regression, firearm ownership was associated with LEO homicide rates per 10,000 officers (IRR = 1.040, p = 0.009); the relationship between violent crime rate and LEO homicides approached significance (IRR = 1.002, p = 0.073). These results were supported by cross-sectional and longitudinal sensitivity analyses. LEO homicide rates were three-times higher in states with high firearm ownership compared to states with low firearm ownership. Conclusions. High public gun ownership is a risk for occupational mortality for LEOs in the U.S. States could consider methods for reducing firearm ownership as a way to reduce occupational deaths of LEOs.
