Abstract

We examine whether retaliatory violence exists between law enforcement and citizens while controlling for any social media contagion effect related to prior fatal encounters. Analyzed using a trivariate dynamic structural vector-autoregressive model, daily time-series data over a 21-month period captured the frequencies of police killed in the line of duty, police deadly use of force incidents, and social media coverage. The results support a significant retaliatory violence effect against minorities by police, yet there is no evidence of retaliatory violence against law enforcement officers by minorities. Also, social media coverage of the Black Lives Matter movement increases the risk of fatal victimization to both law enforcement officers and minorities. Possible explanations for these results are based in rational choice and terror management theories.

摘要

我们研究了在控制与先前致命遭遇相关的任何社交媒体传染效应的情况下，执法部门与公民之间是否存在报复性暴力。使用三变量动态结构向量自回归模型进行分析，21个月期间的每日时间序列数据记录了因公殉职警察的频率、警察致命使用武力事件以及社交媒体报道。结果支持警察对少数群体存在显著的报复性暴力效应，但没有证据表明少数群体对执法人员存在报复性暴力。此外，社交媒体对“黑人的命也是命”运动的报道增加了执法人员和少数群体遭受致命伤害的风险。这些结果的可能解释基于理性选择和恐怖管理理论。
