One of the most acute social justice problems in the United States is the direct conflict between police and minorities. Media coverage of police brutality instances not only allow such inequitable practices come to light, but is an important step towards the reform of inappropriate policing. However, it is theoretically unclear whether the reporting of excessive use of police force on minorities can have a tangible impact on subsequent policing outcomes. In this paper, we aim to answer the question of whether and how digital news on police brutality is effective in shaping subsequent police actions. To address this question, we construct a cross-sectional dataset of news reports of police violence and police traffic stop records. Under a difference-in-difference framework, we find that news reports on police brutality reduces police stops of minorities. Additionally, we find that news with sad frames are more effective in effectuating change in policing behaviors. Finally, we learn that the impact of news reports are less effective in minority-dominated areas and high-crime areas.
