Las Vegas madman Stephen Paddock had recorded the mass shooting from his own hotel room and other surveillance to allow him to see as to when the cops came to the door and closed in on him.

The shooter had at least one camera taping him unleashing the hell that he brought to many citizens down below and the other watching the door.
Apparently knowing cops would eventually catch up to him, he also wired cameras in the hallway outside his room so he could see when the heat was getting close, the Daily Mail reported.
Paddock killed 59 people and injured more than 500 in the worst mass shooting in US history.
