Despite the widespread interest that de-escalation training has attracted in law enforcement contexts over the past few years, we know little about its effectiveness in reducing use of force incidents. This study seeks to ascertain the effect of de-escalation training on serious use of force events in Camden, a high-crime and high-poverty city in New Jersey. An analysis of individual officers suggested de-escalation training had no significant effects on serious force, whereas a synthetic control analysis of the entire department suggested that de-escalation training led to a 40% reduction in serious force events. It is suggested that spillover effects between trained and untrained officers may account for the discrepancy.

降级是否成功减少了新泽西州卡姆登县严重使用武力的情况？力结果的综合控制分析

尽管在过去几年中，降级培训在执法环境中引起了广泛关注，但我们对其在减少使用武力事件方面的有效性知之甚少。本研究旨在确定降级培训对新泽西州高犯罪率和高贫困城市卡姆登的严重使用武力事件的影响。对个别军官的分析表明，降级训练对严重武力没有显着影响，而对整个部门的综合控制分析表明，降级训练导致严重武力事件减少了 40%。有人认为，受过培训和未经培训的官员之间的溢出效应可能是造成这种差异的原因。
