That part was more a joke than anything.An arrest doesn't (or rather shouldn't) involve a physical assault tho. You basically said the cop would be justified in physically assaulting him, you didn't say it would be ok for the cop to arrest him. You specifically mentioned assaulting him. You think that would be justified?
Just alluding to the way cops arrest people. No doubt he would have been roughed up.
And no I wouldn't condone they beat him, but had he been arrested I would not have felt sympathy in the way I do when I usually see these videos. Black people get killed for much less almost daily.
