The U.S. Supreme Court ruled Friday to throw out the federal ban on “bump stocks,” an attachment that allows semiautomatic rifles to fire at a speed comparable to a machine gun, prompting a blistering dissent from liberal Justice Sonia Sotomayor.
In a 6-3 vote on ideological lines, the court's conservative justices decided that a 1986 law aimed at banning machine guns cannot be interpreted to include bump stocks, NBC News reported.
