"Second Amendment Fundamentalism" in the NRA

Ryan Busse went to work for the firearms manufacturer Kimber America, where he was so good at marketing the weapons that he became a rising star of the industry. But over the years, he became disillusioned when he saw the NRA refuse to consider gun controls after mass shootings. His new book is 'Gunfight: My Battle Against the Industry that Radicalized America'.

New York Times reporter Danny Hakim discusses conflicts within the NRA's leadership, its lawsuit against its advertising and PR company, and what leaked documents reveal about the organization.

For trauma surgeon Joseph Sakran, gun violence is a very personal issue. He has treated hundreds of gun wound victims, comforted anxious loved ones and told mothers and fathers that their children would not be coming home.

But Sakran's empathy for his patients and their families extends beyond the hospital. Sakran knows the pain of gun violence because he is a survivor of it; when he was 17, he took a bullet to the throat after a high school football game.
