警务技术的意外后果
The Unintended Consequences of Policing Technology
摘要
Abstract Technology is integral to police departments, automating officer tasks, but inherently changing their time allocation. We investigate this by studying ShotSpotter, a technology that automates gunfire detection. Following a detection, officers are dispatched to the scene, thereby reallocating their time. We leverage this shock to officers’ time allocation using the rollout of ShotSpotter across Chicago police districts to study the effects on 911 response. We find consequences for calls unrelated to gunfire—officers are dispatched slower (22%), arrive on-scene later (13%), and the probability of arrest is decreased 9%. Consequently, departments must evaluate their resource capacities prior to implementing technologies.

摘要 技术已成为警察部门不可或缺的一部分，自动化了警员的任务，但同时也从根本上改变了他们的时间分配。我们通过研究ShotSpotter——一种自动化枪击检测技术——来探讨这一问题。在检测到枪击后，警员会被派遣至现场，从而重新分配其时间。我们利用ShotSpotter在芝加哥各警区的推广作为警员时间分配的外生冲击，研究其对911响应的影响。我们发现，对于与枪击无关的呼叫产生了后果——警员派遣速度减慢（22%），到达现场时间延迟（13%），逮捕概率下降9%。因此，部门在实施技术之前必须评估其资源能力。
