Ok...it took the Las Vegas PD about 90 minutes to find the shooter. They have no leads or no possible motive. The shooter's girlfriend appeared to be in an abusive relationship with him where it's been reported he readily berated her in public.

The shooter made over $5 million last year from gambling. How is all this possible? Has he come back from the future that he is beating the odds time and time again? 

Maybe it's that the FBI and Las Vegas PD are a bunch of idiots and believe what they're being told? There was some sort of "note" in the ugly hotel room where the shooter killed himself. All this sounds like nothing but a bunch of incompetent people involved. The worst part is the authorities will never know his motive...but I am sure his girlfriend has some sort of idea even if she has blocked it out of her mind or is too clueless to realize why the shooter did what he did...or she's in on it too.
