Prior deadly force research has sought to identify appropriate mechanisms that can effectively control police officers' decisions to use deadly force. However, the relative impact of external discretion control policies on police shooting behavior remains largely unknown. Using data from Philadelphia for a period of more than two decades, this article employs interrupted time-series analysis (ARIMA) to examine the impact of legislation and judicial intervention on use of deadly force by Philadelphia police officers. The article also considers the impact of larger, community-level characteristics on levels of deadly force. Findings produced modest support for the potential effect of external discretion control policies and community-level factors on police shooting behavior but generally suggest that dynamic changes in the internal working environment can outweigh the influence of the external mechanisms.
先前关于致命武力的研究试图确定能够有效控制警察使用致命武力决策的适当机制。然而，外部自由裁量权控制政策对警察枪击行为的相对影响在很大程度上仍不为人知。本文利用费城二十多年的数据，采用中断时间序列分析（自回归积分滑动平均模型）来检验立法和司法干预对费城警察使用致命武力的影响。本文还考虑了更大范围的社区层面特征对致命武力水平的影响。研究结果对外部自由裁量权控制政策和社区层面因素对警察枪击行为的潜在影响提供了一定支持，但总体表明内部工作环境的动态变化可能超过外部机制的影响。
