A 2018 policy brief by the Rockefeller Institute of Government and the State University of New York researched incidents that resulted in deaths and injuries, excluding gang and terrorist violence, and found that although whites make up the majority of mass shooters, the number is not overwhelming, the Washington Times reported.
“Despite common misperceptions that all mass shooters are white, the findings indicate that while a majority are, this proportion is just over half of the perpetrators (53.9 percent),” the study found. “More than one in four shooters is black and nearly one in ten is of Hispanic descent.” \cite{Zhou_1988,Boyer_1998} .
