"It was a constant pressure among white racists to keep guns out of the hands of African-Americans, because they would rise up and revolt. The KKK began as a gun-control organization. Before the Civil War, blacks were never allowed to own guns. During the Civil War, blacks kept guns for the first time — either they served in the Union army and they were allowed to keep their guns, or they buy guns on the open market where for the first time there's hundreds of thousands of guns flooding the marketplace after the war ends. So they arm up because they know who they're dealing with in the South. White racists do things like pass laws to disarm them, but that's not really going to work. So they form these racist posses all over the South to go out at night in large groups to terrorize blacks and take those guns away. If blacks were disarmed, they couldn't fight back."
