I admittedly still have a zillion questions as to what this third guy's role was. It seems there is a lot of contradictory information being disseminated. Morally, I find it reprehensible that he did not call 911 or intervene, but simply kept filming. That makes me suspicious that he was, as you suggest, involved.

I think we may finally get to the truth. At least I hope so.

but I would imagine police are checking phone communications and other evidence.

Bryan makes some comments in this video report...

and someone released it to the public (two months later).

It seems like the original police/prosecutor first looked at that video (which probably was turned over by the guy who took it) and saw a black man running at a pickup truck in order to demolish it, and stopped on that terrible crime only to attack a man pointing a loaded shotgun at him, and...

I can't even imagine. Literally they saw a man who has been chased by a truck with two armed men trying desperately to avoid being killed, and he gets killed, and the killer is the victim.

Are these prosecutors elected in Georgia? I'd love to contribute to anyone running against that filth.

Was it going to be posted on social media. He was in on it.
