  • Police now say 23 firearms and thousands of rounds of ammunition were found in Stephen Paddock's hotel room.
  • A number of those weapons were semi-automatic. This means they fire a single shot when the trigger is pulled, not multiple rounds like a fully automatic weapon.
  • BUT they had been modified with something called a "bump stock.” This device, which is legal to buy, automates the trigger pull process and allows shooters to fire at a rate of 400 to 800 rounds per minute.
