TBH it’s probably fake and lame, dude was standing for minutes after it happened
The part that gives me the most thought about it being planned was his response, he gets up and raises his fist? His security doesn’t hold his head below cover and he just chills on stage for the photo op? If he was unexpectedly shot you’d think he would just be crying and shidding himself, maybe they are just poorly trained
Edit: In case anyone is reading this later it was definitely not likely to have been staged.
