CNN —For Michael Cargill, the thorny dispute over bump stocks is only partly about the controversial devices themselves. Responding to grisly crimes in which machine guns were used to rob banks or ambush police, lawmakers stepped in and initially required owners to register the weapons. The agency estimated that as many as 520,000 bump stocks were sold between 2010 and 2018. Bump stocks replace a semi-automatic rifle’s regular stock, the part of a gun that rests against the shoulder. “We’ll never forget the sound of the machine gun firing into the crowd that night,” Marano said.
