The debate over police use of military equipment often revolves around the supposed tradeoff between increasing police safety and reducing killings by the police. In this paper, I rely on institutional features that exogenously determine the distribution of military equipment to US police departments to show that, contrary to previous evidence, there is no such tradeoff: police militarization increases killings by the police and reduces police safety. Each year police militarization results in 64 additional killings by the police, 12,440 police officer assaults, and 2653 police officer injuries.

警察安全、警察杀人以及美国执法的军事化

关于警察使用军事装备的辩论通常围绕着增加警察安全和减少警察杀人之间的假定权衡展开。在本文中，我依靠外生决定向美国警察部门分配军事装备的制度特征表明，与之前的证据相反，不存在这样的权衡：警察军事化增加了警察的杀戮并降低了警察的安全。每年警察军事化导致 64 起警察额外杀害、12,440 名警察袭击和 2653 名警察受伤。
