We're two months in and magically this stuff starts up again after 4 years of low or no shootings. The Las Vegas shooting was almost assuredly an Saudi assassination attempt on US soil. This is assuredly some CIA or other program to radicalize or straight pay them off to do these things.
Basically the crown prince was in Vegas gambling on the down low. Various Saudi factions paid for an assassin squad to take him out. That’s why Paxton or whoever had a room slap full of guns and ammo like that. The room the deal went down in was a floor below the four seasons that is also Saudi owned. So they were basically just going to fight their way up the stairs and kill him.
However he had slipped out and some random security guard called the cops due to assailants barricading the floor. So the deal went south and they shot the Paxton guy and then decided to cover by shooting into the crowd and at some fuel tanks to cause a diversion.
There’s video of the fbi being in all the casinos trying to find the prince and escorting him out. This is why we never heard anything more about it, because the fbi covered it up. If you recall shortly thereafter Trump went to Saudi Arabia and the country started liberalizing and arrested a shit ton of the royal family, amongst other things. The general theory was trump put the fear of god into the king and made a deal to keep it quiet.
