Changing police use of force policies and training to incorporate de-escalation tactics is one of the most routinely recommended police reform measures. Despite widespread promotion and proliferation of de-escalation trainings, to date, no research has empirically demonstrated that these trainings reduce use of force in the field (Engel, R. S., McManus, H. D., & Herold, T. D., 2020). Therefore, it is unknown if de-escalation trainings actually reduce force, have no impact, or have unintended consequences that possibly increase injuries to officers or citizens. We collaborated with the Louisville Metro Police Department (LMPD) in 2019 to evaluate the impact of the Integrating Communications, Assessment, and Tactics (ICAT) de-escalation training developed by the Police Executive Research Forum. Using a stepped-wedge randomized controlled trial research design, the panel regression results demonstrated statistically significant reductions in use of force incidents (−28.1%), citizen injuries (−26.3%), and officer injuries (−36.0%) in the post-training period. These significant reductions were larger than any changes in LMPD arrest patterns during the same period. Other possible time-based confounders were also considered; the combined analyses show robust, consistent, and immediate impacts on use of force counts after training.

评估降级培训对警察行为的影响:在肯塔基州路易斯维尔市地铁警察局减少警察使用武力

改变警察使用武力的政策和培训以纳入降级策略是最常被推荐的警察改革措施之一。尽管降级培训得到了广泛的推广和推广,但迄今为止,没有研究表明这些培训可以减少该领域的武力使用(Engel, RS, McManus, HD, & Herold, TD, 2020)。因此,尚不清楚降级训练是否真的会减少武力、没有影响或产生可能增加官员或公民受伤的意外后果。我们于 2019 年与路易斯维尔地铁警察局 (LMPD) 合作,评估由警察执行研究论坛开发的整合通信、评估和战术 (ICAT) 降级培训的影响。使用阶梯楔形随机对照试验研究设计,面板回归结果表明,在使用武力事故(-28.1%)、公民伤害(-26.3%)和军官伤害(-36.0%)后,在统计上显着减少。训练时期。这些显着减少大于同一时期 LMPD 逮捕模式的任何变化。还考虑了其​​他可能的基于时间的混杂因素;综合分析显示了对训练后使用武力数量的稳健、一致和直接的影响。这些显着减少大于同一时期 LMPD 逮捕模式的任何变化。还考虑了其​​他可能的基于时间的混杂因素;综合分析显示了对训练后使用武力数量的稳健、一致和直接的影响。这些显着减少大于同一时期 LMPD 逮捕模式的任何变化。还考虑了其​​他可能的基于时间的混杂因素;综合分析显示了对训练后使用武力数量的稳健、一致和直接的影响。
