In this case, I probably would not.
Why "IN THIS CASE"?
Maybe if it was an IMMEDIATE reponse to the close proximity, I could see your point - I was tossing him to create space, I feared for cop's safety, etc.
but this was AFTER they searched him, cussed him out, he was explaining and apologizing, and he was up against the cop car, ,completely not resisting, completely obeying the cops.
He was shoved to the ground as punishment, not as part of police mgmt. He was issued a "parting shot".
I am literally shocked that a conservative like yourself is okay with cops shoving people hard to concrete as parting shots. Shocked, really. You yell about obama stealing our rights, but you're okay when cops do it? Fuck, man.
