Objectives

Outfitting police officers with body-worn cameras (BWCs) has been suggested to improve police-community relations. This study evaluates whether the deployment of BWCs on NYPD officers impacted resident perceptions of the police.

Methods

A cluster randomized controlled trial design was used to test the influence of BWCs on resident perceptions of the NYPD in treatment precincts relative to control precincts. Dual-frame randomly selected telephone surveys were used to collect pre-intervention and post-intervention resident perception data.

Results

We find no statistically significant differences between BWC treatment and control precincts in general perceptions of the NYPD or the average assessment of police officer behavior among those who have had recent encounters with the NYPD.

Conclusion

Strong community support for BWC adoption and citizen expectations for videos of controversial policing events suggests the continued use of this technology. However, BWCs should be implemented with other evidence-based programs to enhance police-community relations.

随身携带的摄像头会改善社区对警察的看法吗？受控实验评估的结果

目标

有人建议为警察配备随身携带的相机 (BWC)，以改善警察与社区的关系。这项研究评估了向纽约警察局官员部署 BWC 是否影响了居民对警察的看法。

方法

集群随机对照试验设计用于测试 BWC 对治疗区相对于控制区的纽约警察局居民看法的影响。双帧随机选择电话调查被用来收集干预前和干预后的居民感知数据。

结果

我们发现 BWC 治疗区和控制区之间在纽约警察局的一般看法或最近与纽约警察局接触过的警察行为的平均评估方面没有统计学上的显着差异。

结论

社区对采用 BWC 的大力支持和公民对有争议的警务事件视频的期望表明继续使用该技术。然而，生物武器公约应与其他循证计划一起实施，以加强警察与社区的关系。
