“...but the thing that was intentional and is really bad is that the cop who shoved him wouldn’t let anybody else stop to help him...”
Absolutely not true.
Guys in camo were kneeling beside him WITHIN seconds.
Watch the video again!
No, a cop next to the one who shoved the guy stopped and ran back to help the man and the cop who had shoved him then pushed the other cop away and said no, no. It was only when the shover had moved a few feet ahead that the other cops could get to the guy on the ground.
I’m not justifying the elderly “peacenik,” who was stupid, but again it was a situation where one dominant and perhaps too aggressive cop intimidated the others.
