He was using a Glock 23 w/ 165gr Gold dots.
it says it the video description that the bad guy was also firing as he ran out the door. Maybe im just blind, but it looked to me like the guys muzzle was never pointed at the ceiling during the vid. Seems a lot more likely to me that tardo bad guy pulled a shot into the roof from his (insert crappy thug-gun here) when he was running out the door.
