Paddock's girl friend was try to tell people they're going to die is the key to this whole thing. She likely called the police which is why they let her off so quickly.

Because she knew about it before hand makes me partly believe Paddock wasn't the shooter(s.)
It's also likely how the security guard got shot. Her telling the hotel about what was taking place.
This was an ISIS attack.

Wasn’t she out of town when it happened?
