Use of Performance Information and External Accountability: The Role of Citizen Oversight in Mitigating the Motivated Evaluation of Body-Worn Camera Evidence
研究警察随身摄像头对执法结果的影响，发现其效果受职业文化制约，而公民监督机构能缓解种族差异，对公共管理和警务改革有参考价值。
Despite being touted as a game-changing technology, studies on the influence of body-worn cameras (BWCs) on policing outcomes have produced mixed results, with the underlying reasons for such findings unclear. Drawing on the sociology of culture and organizational theory, we argue that BWCs often have mixed impacts due to deeply ingrained, valued occupational assumptions and practices shaped by the structural and organizational context. These assumptions and practices, collectively known as the police métier, are not politically neutral and can lead to motivated decisions rather than accurate ones. We suggest that such motivated reasoning can be mitigated by changing the structural or organizational context, such as establishing a citizen oversight agency (COA), which could decrease racial disparities in policing outcomes. To test these arguments, we examined the impact of BWCs on racial disparities in two types of policing outcomes: police homicides of citizens and disorderly conduct arrests (DCAs). Our findings indicate that while the adoption of BWCs does not impact racial disparities in DCAs or police homicides of citizens, there is a significant decrease in racial disparity in DCAs when BWCs and COAs are used in conjunction. Additionally, while the racial disparity in police homicides of Blacks and Whites does not decrease when BWCs and COAs are used together, there is an overall decrease in police homicides across both racial groups. Overall, our study demonstrates that technology's impact on bureaucratic performance is influenced by occupational assumptions and practices, which can be altered by external accountability mechanisms such as COAs.
