The widespread adoption of bodyworn cameras by police departments across the country promises outcomes that appeal to a broad spectrum of stakeholders, ranging from Black Lives Matter and the American Civil Liberties Union (ACLU) to the International Association of Chiefs of Police and the Police Executive Research Forum. They hope that the presence of bodyworn cameras (“bodycams”) will improve the behavior of police of cers and of people who interact with them. The idea is that the routine recording of policecitizen interactions will encourage compliance with departmental rules and policies, reduce misconduct and unnecessary use of force, ensure accountability, facilitate criminal and disciplinary investigations, and advance racial justice. These hopes are based on the expectation that of cers will behave better when they know that they are being watched (see, e.g., Stanley 2015; Katz 2015; Yokum, Ravishankar, and Coppock 2017). Images can catalyze change. Since 2014, a series of highpro le videos and livestreams of killings and other troubling policecitizen interactions have drawn unprecedented public and governmental attention to racial pro ling and police brutality — longstanding systemic problems that Black, Indigenous, and other nonWhite communities have protested for decades. At the same time, community hopes that images of police misconduct might lead to meaningful accountability have not generally been realized. Whether videos are taken by citizen witnesses or police dashcams or bodycams, footage showing unlawful police behavior has rarely resulted in criminal conviction. In 2018, though, for the rst time in more than fty years, a Chicago police of cer was convicted of murder for an onduty killing — largely because police dashcam videos belied the story told by police of cers who had witnessed the killing (Crepeau et al. 2018).

Bodycams 和性别平等

全国各地的警察部门广泛采用随身携带的摄像机，这有望吸引广泛的利益相关者，从黑人的生命问题和美国公民自由联盟 (ACLU) 到国际警察局长协会和警察执行研究论坛。他们希望随身携带的相机（“随身摄像机”）的存在将改善cer的警察和与他们互动的人的行为。这个想法是，对警察公民互动的例行记录将鼓励遵守部门规则和政策，减少不当行为和不必要的使用武力，确保问责制，促进刑事和纪律调查，并促进种族正义。这些希望是基于这样的期望，即当他们知道自己正在被监视时，他们会表现得更好（参见，例如，Stanley 2015；Katz 2015；Yokum、Ravishankar 和 Coppock 2017）。图像可以催化变化。自 2014 年以来，一系列关于杀戮和其他令人不安的警察公民互动的高知名度视频和直播引起了公众和政府对种族歧视和警察暴行的前所未有的关注——黑人、土著和其他非白人社区几十年来一直抗议的长期系统性问题。与此同时，社区希望警察不当行为的形象可能会导致有意义的问责制，但普遍没有实现。无论视频是由公民目击者还是警察行车记录仪或随身摄像机拍摄的，显示警察非法行为的镜头很少会导致刑事定罪。
