An Evaluation of De-Escalation Training to Understand the Links between Training and Outcomes

Abstract In reaction to high-profile incidents of excessive and deadly force, policymakers, advocates, scholars, and the general public, have all called for police departments to embrace de-escalation training as a method for improving police-citizen interactions. This practice has, in turn, spurred a small, but growing, number of evaluations of police de-escalation training programs. The findings of these studies have been mixed, but incomplete. In particular, we argue that prior studies of de-escalation have been hindered by (1) a lack of consideration of changes in officer behavior in incidents not involving force, (2) a singular focus on whether or not force was used rather than alterations to the “trajectory” of use-of-force encounters, and (3) a failure to measure the intervening mechanisms between de-escalation training and officer behaviors (i.

Screening for Insider Threats in US Law Enforcement: A National Representative Sample of Department Policies and Practices

It is not feasible to examine officer-level risk of engagement as an insider threat at this time.

Another Post about Police Shooting Data

I’ve been screaming this into the void on Twitter lately so I figured I’d pull all my thoughts together in a blog post. On January 12th, ABC News published a story claiming that fatal police shootings had declined 13% in 2021 “amid calls for reform on use of force.” The story also claimed that Florida saw the biggest decrease in shootings (from 93 to 44).1 At that time, The Washington Post’s (WAPO) database was showing 888 fatal police shootings.
