The Supreme Court said a ban on bump stocks — devices that can be added to semi-automatic firearms to make them fire faster — was unconstitutional, striking down a Trump-era law that was put into place after the deadliest mass shooting in U.S. history.
In a 6-3 ruling issued on Friday, Justice Clarence Thomas wrote for the majority that the Bureau of Alcohol, Tobacco and Firearms (ATF) incorrectly ruled that a bump stock turns a semiautomatic rifle into a machine gun.
