So yeah, that video is pretty much exactly how I remember it. Couldnt see much of it because of a huge thing on the screen asking me to disable my adblocker.

But I didnt hear no warning, all I heard was some guy dramatically yelling "Hes got a gun hes got a gun.". There are what look like guards standing against the hall next to her, as well as a guy in a expensive looking suit.

It all seemed like they were making a big show and alot of noise for the camera. No one seemed surprised really by the gun that was aimed at her, but they were all shocked when she got blown away.

Then the guy in the suit asks everyone to get back and starts trying to help her, the whole thing felt scripted, except for the part where they murdered a air force veteran.
