Evidently there were other shootings in LV that night. Here is a video of the Bellagio Hotel having a front window shot out....[www.youtube.com].
This video site also claims the Mandalay hotel has service windows which can be opened and closed. So far I haven't been able verify.
I also found this article which states Mandalay Bay windows have ventilation strips....[www.thewrap.com]
Quotes from the article on these strips.....
"Mandalay Bay also has those little ‘ventilation strips’ that you can slide open if it’s the phobia about air circulating…???"
"Another theory was that Paddock fired through a “ventilation strip,” which is a feature some of of these high-rise hotels utilize to allow a little fresh (desert) air in. Those are purposefully not large enough for a body to fit through."
The absence of muzzle flashes in any of the videos I've seen eliminates the 32nd floor as the shooters primary location.
So I believe we have to assume the shooters were located somewhere else. This location may be a planned decoy? Not that shots weren't fired from this location, because they were. Just not continuous or on the event crowd.
