Reports of racially motivated, fatal shootings by police officers have garnered extensive public attention and sparked activism across the nation. New research from Michigan State University and University of Maryland reveals findings that flip many of these reports on their heads—white police officers are not more likely to shoot minorities citizens than non-white officers.

“Until now, there’s never been a systematic, nationwide study to determine the characteristics of police involved in fatal officer-involved shootings,” said Joseph Cesario, co-author and professor of psychology at MSU. “There are so many examples of people saying that when black citizens are shot by police, it’s white officers shooting them. In fact, our findings show no support for the idea that white officers are biased in shooting black citizens.”

By connecting the findings of police officer race, victim race and crime rates, the research suggests that the best way to understand police shootings isn’t racial bias of the police officer; rather, by the exposure to police officers through crime.

The vast majority—between 90% and 95% – of the civilians shot by officers were actively attacking police or other citizens when they were shot. Ninety percent also were armed with a weapon when they were shot.

Case closed.
