Dr. Ruth Defoster, professor and author of "Terrorizing the Masses," walks through the myths around the causes and solutions to America's gun violence epidemic and debunks NRA and GOP talking points. We discuss gun laws and violence in Chicago, the role of mental illness and video games in mass shootings, as well as, the predictable patterns that nearly all mass shooters exhibit. We also discuss recent shootings including, Parkland, the recent police shooting of Antwon Rose, and the shooting at the Capital Gazette.
