It’s GUN RUNNING. Paddock was running/selling guns. He was a patsy.
How do you get the guns you are going to use in a mass murder to a hotel room?
You get a gun running/selling patsy to do it for you. Not your guns, not your room, kill patsy to look like suicide, you were never there. Perfect!
Gun running makes a ton of sense re selling in the hotel and bringing up the guns. And laundering profits through gambling. But why were they all different weapons he purchased at retail? That makes no sense. He didn’t have two of anything. He bought them from retail venues.
And why not? It’s more rational than the tale that’s been spun.
