[Meet the New Boss]

If his accomplice didn’t show, then why continue? Or at least call the valet and have his car brought around, park it over there himself and take a taxi back. He’d have been delayed a few minutes but it wasn’t like the music crowd was going anywhere. They’d have still been there.

Let's say he broke out the windows first. Then he started trying to locate the minivan full of tannerite which let's say was supposed to be parked near the fuel storage tanks. He doesn't see it.

Having broken out the glass, he knows he is on the clock with respect to leading people back to his room. Maybe people see the glass on the ground and look up, tell hotel employees, and ultimately leads to his room.

So he just goes ahead and at least shoots up the crowd.

It was night time. Too dark to see the van. If Paddock was gonna blow the van, it would have been deployed somewhere. Who ever has that missing rifle, was also supposed to deploy the van. Imho.

He should have had better notes.

Buy guns and ammo.
Get rooms with a view.
Use the binoculars to make sure Mohammed pulls the car to the tanks.
Then and only then, break the windows and proceed as planned.
