Peacekeeping Force: Effects of Providing Tactical Equipment to Local Law Enforcement

We provide the first local level empirical analysis of the causal effects of providing military equipment to local police. Employing a novel combination of publicly available county-year panel data matched to hand-collected data on citizen complaints, we investigate the effects of acquiring tactical weapons, optics, and vehicles on citizen complaints, assaults on police officers, and offender deaths. For causal identification, we exploit exogenous variation in equipment availability and cost-shifting institutional aspects of the 1033 Program. Our results indicate that these items have generally positive effects: reduced citizen complaints, reduced assaults on officers, increased drug crime arrests, and no increases in offender deaths.
