The power of protest on policing: Black Lives Matter protest and civilian evaluation of the police
通过在线调查实验，研究2020年黑人的命也是命抗议如何影响美国黑人和白人对警察的评价，发现抗议降低了安全感和警察信任度，且对白人影响更大。
Abstract In 2020, police brutality against Black Americans catalyzed Black Lives Matter (BLM) protests across all 50 states. Though BLM protests continue to permeate society, few scholars explore how these protests change Americans' perceptions of the police. To investigate this phenomenon more meticulously, we administered an online survey experiment—oversampling Black American participants—to measure how protest culture, specifically BLM protests, influences civilians' perceptions of the police. Our survey found that (1) Black American participants have a lower evaluation of police performance, but a higher evaluation of the BLM Movement than White American participants; (2) the presence of a general protest negatively impacts peoples' perception of safety, police trustworthiness, and police performance; and (3) a BLM protest casts a stronger effect on White American participants than on Black American participants. Using Critical Race Theory and QuantCrit these findings suggest that the visibility of BLM protests changes both Black and White perceptions of the police to varying degrees.
