Police Violence and Public Perceptions: An Experimental Study of How Information and Endorsements Affect Support for Law Enforcement

Incidents of police violence can undermine trust in legal authorities. Whether such incidents have this effect will depend on how citizens evaluate victims, the police, and public officials. Citizens’ evaluations may be shaped by information about (1) a pattern of police violence and (2) government responses. We study citizens’ reactions to police violence by randomly assigning these two types of information in the context of the Stephon Clark shooting in Sacramento. We find that information influences levels of blame for and trust in the police, but the effects depend on citizens’ race and whether they live in the community where the violence occurred. In contrast, information does not alter citizens’ perceptions of local police officer organizations and, in turn, their willingness to follow police endorsements in elections. These results suggest a catch-22 whereby police violence can diminish the standing of police personnel, but favorable local opinion preserves their political influence.
