it's like he faced a hail of bullets, and the best they could do is graze him.

But... with this one.. im sketchy..

That video isn't anywhere near the high-speed required to capture a bullet. Its framerate is a lot lower.

I've also watched it a few times and i'm under the impression someone in the crowd threw something because it does a clear arc and fall due to gravity.. something little like popcorn or a spitball sized garbage/paper .. maybe even a cigarette butt.. but something small tossed by someone.

I think the chance angle of the camera creates an optical illusion, that can be woven into the hype and take advantage of it that it may have been a bullet.

But i don't think that was moving fast enough to be a bullet. This is just my 5 minute take.
