The impact of police officer diversity on police-caused homicides

Macrolevel studies of police killings generally focus on testing the conflict and community violence hypotheses. This research generally supports both the conflict proposition that minority threat is related to police violence and the community violence proposition that locations with higher levels of violence have a greater number of police-caused homicides. However some of the most common proposals to reduce police-citizen violence, namely changing police personnel, are largely overlooked in existing research. The majority of studies that have examined police homicides do not acknowledge the possibility that the personnel composition of police agencies may affect levels of police violence. The current article extends previous lines of research on police-caused homicides by including measures of the personnel composition, of police agencies as predictors of police-caused homicides. More specifically, this study examined the influence of minority and female representation within large municipal police agencies on police-caused homicides. The findings show that more diversified departments do not have significantly lower levels of police-caused homicides. The results do, however support both the conflict and community violence propositions. Furthermore, the pattern of findings suggests the existence of a generalized threat in the nation's largest cities.
