Purpose

The current study examines the effect of changing a specific use-of-force policy coupled with de-escalation training implementation on patterns of police use of force.

Design/methodology/approach

An interrupted time-series analysis was used to examine changes in police use-of-force incident records gathered from a large, southwestern US metropolitan police department from 2013 to 2017 based on a TASER policy change and de-escalation training implementation mid-2015.

Findings

Results demonstrate that changes to use-of-force policy regarding one type of force (i.e. use of TASERs) coinciding with de-escalation training influence the prevalence of use-of-force incidents by increasing the reported police use-of-force incidents after the changes were implemented. This finding is somewhat consistent with prior literature but not always in the desired direction.

Practical implications

When police departments make adjustments to use-of-force policies and/or trainings, unintended consequences may occur. Police administrators should measure policy and training outcomes under an evidence-based policing paradigm prior to making those adjustments.

Originality/value

This study is the first to measure the effects of changing use-of-force policy and implementing de-escalation techniques in training on patterns of police use of force and shows that these changes can have a ripple effect across types of force used by police officers.

政策和培训的变化是否会影响警察使用武力的模式？中断的时间序列分析

目的

当前的研究考察了改变特定的武力使用政策以及降级培训实施对警察使用武力模式的影响。

设计/方法/方法

基于 2015 年中期 TASER 政策变化和降级培训实施，使用中断的时间序列分析来检查从 2013 年到 2017 年从美国西南部的一个大型都市警察局收集的警察使用武力事件记录的变化。

发现

结果表明，关于一种武力（即使用泰瑟枪）的武力政策的变化与降级训练同时发生，通过增加报告的警察使用武力事件来影响使用武力事件的发生率。更改已实施。这一发现与先前的文献有些一致，但并不总是朝着理想的方向发展。

实际影响

当警察部门对使用武力政策和/或培训进行调整时，可能会出现意想不到的后果。在进行这些调整之前，警察管理人员应在基于证据的警务范式下衡量政策和培训成果。

原创性/价值

这项研究是第一个衡量变化的使用武力政策和在培训警察使用武力的方式上实施降级技术的效果的研究，并表明这些变化可能对警官使用的各种武力产生连锁反应.
