The adoption of body-worn cameras (BWCs) is often promoted in response to contentious police use of force incidents involving minority civilians. BWCs are expected to improve policing outcomes by enhancing accountability, although researchers have yet to determine whether BWCs can reduce racial/ethnic disparities. I examine whether BWCs mitigate the influence of neighborhood racial/ethnic context on arrests and use of force using cross-classified logistic regression models to examine the outcomes of 900,000+ police–civilian contacts in Phoenix. Arrests were significantly more likely to occur in Hispanic and Black neighborhoods before and after BWC deployment, even accounting for situational, officer, and neighborhood characteristics. When BWCs were activated in Black neighborhoods, the odds of arrest decreased by 38%. However, BWCs did not moderate the influence of neighborhood percentage of Hispanic on arrest. The neighborhood racial/ethnic context was not associated with the use of force pre- or post-BWC deployment.

随身携带的摄像头会减少少数族裔社区警察行为的差异吗？黑人和西班牙裔社区微妙影响的证据

为应对涉及少数族裔平民的有争议的警察使用武力事件，通常会提倡采用体戴式摄像机 (BWC)。BWC 有望通过加强问责制来改善警务结果，尽管研究人员尚未确定 BWC 是否可以减少种族/民族差异。我使用交叉分类逻辑回归模型检查了 BWC 是否减轻了邻里种族/民族背景对逮捕和使用武力的影响，以检查凤凰城 900,000 多名警察-平民接触的结果。在 BWC 部署之前和之后，西班牙裔和黑人社区发生逮捕的可能性要大得多，即使考虑到情境、官员和社区特征。当 BWC 在黑人社区被激活时，被捕的几率降低了 38%。然而，BWC 并没有缓和西班牙裔社区百分比对逮捕的影响。邻里种族/民族背景与 BWC 部署前后的武力使用无关。
