The first time I watched this video I was immediately drawn to this guy, like why is he prancing off like that right before shit goes down?

Then I watch it a few more times and I see he has that gun in his hand which appears to be similar or the same as the victim’s gun.

Then I watch a few more times and it looks like dude in the gray may have accidentally discharged the gun and was the first shot which then initiated the others to begin firing.

So this guy rushes in, takes the victim’s holstered weapon and shoots it as he runs away, which causes all the other itchy trigger fingers to fire, and dude just disappears? Wtf is going on…

Edit I watched the other angle, I no longer think what I said above.
