The thing I'm finding hard to believe about this whole story is how long it apparently took the cops to find his room. It took them...how long? We're expected to believe that they had no idea which floor he was on, and had to work their way down from the top. They're now saying they only found him after the smoke from his guns set off a fire alarm.
Really?
First of all, he shot out two huge floor to ceiling windows on a high floor. Even in the dark (which isn't really
that dark in Vegas), it would have been a simple matter to identify the building the shots were coming from, scan the facade of identical glass panels, see the broken ones, observe the flashes of gunfire coming from them and work out from there which floor he was on and also where on that floor he was located.
Not only that, but I'm presuming there were many other guests staying on the same floor as him. The noise from those guns would have been deafening. Do they really expect us to believe that nobody heard the din from constant automatic gunfire on their floor and reported it? Either the Vegas police are uncommonly stupid, or there's something which doesn't pass the smell test about this whole account.
