After Texas Massacre, Drexel Prof. Asks: "What Makes White Men So Prone to This Kind of Behavior?"

Sunday's shooting in Sutherland Springs, Texas, was one of the deadliest mass shootings in Texas state history. It comes only a month after the shooting massacre in Las Vegas, where another white man, Stephen Paddock, opened fire on concertgoers, killing 59 people, including himself. The majority of mass shootings are carried out by white men. For more on the connections between race, white supremacy and mass shootings, we speak to George Ciccariello-Maher, political science professor at Drexel University and the author of "Decolonizing Dialectics." He was banned from campus after questioning why mass shootings in the United States are almost always carried out by white men.
