Did Saudi Prince Al Waleed bin Talal help facilitate Vegas shooting in Oct?

In Las Vegas, Prince Alwaleed owned 4 upper floors of the Mandalay Bay resort, including the 32nd floor,  Several  witnesses observed shooting from more than one location.

The Mandalay Bay has a heli pad on the roof. That is important, because that was the escape route after the carnage.
Paddock, the alleged shooter, was a pilot. He was also a gun runner between the Philippines and the U.S. He was running guns for Prince Alwaleed. Paddock didn't win his fortune at the casinos. His millions came from smuggling,  Also, King Salman was in Las Vegas. Salman was at the Tropicana.
The FBI knew Paddock was running guns. They were tipped off, but they didn't know there would be an assassination attempt on Salman by Alwaleed just down the strip.
Paddock brought the guns as he usually did.
