Alito says he's sure Congress wanted to ban a rapid-fire gun device, but overturns the rule anyway

• The Supreme Court threw out a ban on bump stock devices.
• The devices allow rifles to fire bullets quickly and were used in the 2017 Las Vegas mass shooting.
• Justice Samuel Alito wrote Congress would agree with a ban, but still struck the ban down.

There's "little doubt," Supreme Court Justice Samuel Alito wrote, that Congress would have considered bump stocks akin to a machine gun.

The devices — which allow semi-automatic rifles to fire bullets at nearly the rate of machine guns — were banned by federal authorities in 2018 after the Las Vegas shooter used them to kill 60 people and wound over 400 more.
