Why have public reactions to police misconduct been so polarized, and why have opposing social movements emerged in response? This study explores attributions of police misconduct, using a myriad of possible attributions and a population-matched national sample ( N = 700), to extend our understanding of the perceived causes of police misconduct and who holds which attributions, focusing on race, racial attitudes, and political ideology. We find that attributions could be divided into (a) multifaceted attributions—the belief that misconduct has multiple causes; and (b) excusatory attributions—the belief that misconduct is caused by factors external to police officers and agencies. Endorsement of these attributions stems from racial and political attitudes, with mediation analyses finding that race plays an indirect role in endorsing attributions of police misconduct. As such, efforts to address police misconduct face not only a political power struggle but also a racially attitudinal one.
