I suspect that Mandalay would have a more sophisticated set up than a couple of hotel dicks. I was thinking less about stopping the perp than collecting and disseminating info to LE, protecting guests, assisting evac. And I suppose it was too much to hope that a proactive security team catch the perp before he could do anything. Ex: a guest who refuses maid service for days should at least rate a visit from security, a knock on the door inquiring if everything was ok.
Therefore..... inside job
Has to be info on where paddock’s meals came from .. one would think
I expect the hotel fed all the info they had to the police and hotel security were told by the LE to hang back. They would be gathering helpful info and making sure guests are safe. I dunno about before the shooting. I’m wondering how the guy brought in all the weaponry and other equipment (e.g. camera setup).
