A bump stock is an attachment that converts a semi automatic rifle into a weapon that can fire as many as 800 rounds per minute - an intensity of gunfire matched by machine guns. The deadliest mass shooting carried out by a single shooter in US history - the October 2017 Las Vegas massacre - was enabled by a bump stock. On Friday, the US Supreme Court struck down a Trump-era bump stock ban introduced in the wake of that tragedy, in which 60 people were killed and hundreds more injured. Writing for a perfectly partisan six to three majority, gun enthusiast and ultra conservative Justice Clarence Thomas, decided the administration had overstepped its authority enacting the ban, and based the decision in a very technical, very weird reading of the statute. On this Opinionpalooza edition of Amicus, Dahlia Lithwick is joined by Slate’s senior writer on the courts and the law - Mark Stern, and David Pucino, Legal Director & Deputy Chief Counsel of Giffords Law Center to Prevent Gun Violence. Together, they discuss the careful reasoning and research behind the ban, Justice Thomas’ self-appointment as a bigger gun expert than the agency charged with regulating guns - the ATF, how the gun industry used its own “amicus flotilla” from extreme groups to undermine the agency, and how the industry will use this roadmap again. But, please don’t despair entirely, you’ll also hear from David about hope for the future of gun safety rules.
