Politico published an interview last Friday with two criminologists who have studied mass shootings. Jillian Peterson is a professor of criminology at Hamline University and James Densley is a professor of criminal justice at Metro State University. Together, they’ve created a database of mass shootings since 1966 along with a detailed life history of 180 shooters. Their research points to a number of commonalities among them. Right away, they highlighted the role of the media and social contagion in these events, suggesting a connection between the Buffalo shooting and the one in Uvalde.
