This year, the U.S. has seen more than 270 mass shootings — and firearms remain the leading cause of death for American children and teens. But solutions appear largely out of reach. New York Times reporter Mike McIntire, a gun owner himself, traces how we got here in his new book, Ricochet: Guns, Greed, and the American Way of Violence. McIntire talks to Apple News In Conversation guest host David Greene about the surprising origins of the Second Amendment, how an obscure Democrat helped turn the National Rifle Association into a powerful lobby, and paths to reducing violence.
