It was 11 minutes of hell. Las Vegas killer Stephen Paddock had a perfect vantage point from a hotel window, looking down on thousands of concert-goers below and he had a lot of guns. 23 just in the hotel room, more at home.

But as the nation mourns, there is a growing focus on the kind of weapons used and one gun accessory in particular.  It’s called a “bump stock,” some say it can turn a semi-automatic weapon into an automatic weapon.
