Police use of violence may threaten police agencies’ effectiveness by reinforcing residents’ legal cynicism and disengagement from police. We examined police lethal violence against Black people and its relationship with clearance by arrest in a sample of Black victims’ crime incidents in over 350 jurisdictions in 2015, via Mapping Police Violence and the National Incident-Based Reporting System (NIBRS). We calculated each crime incident's unique time-varying exposure to police lethal violence, with an accompanying agency-level measure that averaged this incident-level measure. Under our original measures, multilevel survival analysis showed a statistically significant association with clearance for the agency-level average exposure measure, but not for the time-varying incident-level exposure measure. Subsequent exploratory analyses suggested a possibly shorter-lived relationship with incident-level police lethal violence exposure, which should be investigated in future research.

在警察致命暴力之后清除犯罪

警察使用暴力可能会加剧居民对法律的冷嘲热讽和脱离警察，从而威胁警察机构的效力。我们通过映射警察暴力和国家基于事件的报告系统 (NIBRS)，在 2015 年 350 多个司法管辖区的黑人受害者犯罪事件样本中检查了警察对黑人的致命暴力及其与逮捕许可的关系。我们计算了每起犯罪事件随时间变化的独特暴露于警察致命暴力的情况，并附带一个机构级别的衡量标准，该衡量标准对该事件级别的衡量标准进行了平均。在我们最初的测量中，多级生存分析显示，机构级平均暴露测量与清除率存在统计学显着相关性，但与随时间变化的事件级暴露测量无关。
