It was a sucker-punch; the white cop distracted him and the black cop wound up and delivered the blow. That cop is lucky.
I heard about a kid who went down for manslaughter— a long time ago. It was a street fight and the kid won. He punched the other kid’s lights out. But that kid fell and hit the back of his head on the sidewalk.
It was the second blow that killed him. but that made no difference in court.
You ain’t wrong. And that scenario you described has happened more than once and more than one guy is in prison because of it.
