Consider what McGlocklin did. Upon seeing some whacko screaming at his partner, he stolls up slowly, not rushing or even trotting. One shove to get the harasser away from his partner and car, and no further aggressive action.
This is not true. The video clearly shows the shover moving toward the downed man. He stops and backs up when the downed man reaches for his gun.
It's incredible to me how difficult it is for facts to stay straight on a critical thinking forum.
