Trump's idea to ban bump stocks is not a new one. After the Las Vegas mass shooting in October, he signaled a willingness to discuss regulating or banning the kits that allow people — like the shooter in that case, who fired down on a crowd from his hotel suite — to make their legal semi-automatic rifles operate like illegal, rapid-fire automatic weapons. The administration later clarified that any crackdown should be regulatory, not statutory. That stance is shared by the NRA, which opposes any new gun control laws.
