One thing about the footage is that when he's shooting toward the walls there is no damage at all. Some of the point blank shots where he unloads on the "bodies" shows zero blood or damage. There is no blood spray from any arterial wounds which would make a tremendous mess... you'd also have plenty of "active" wounded who would be still capable of movement and more importantly would be panicking all the way until blood loss would remove their ability to function.

Worst hoax ever... like they intentionally made this look hoaky as hell.
