This is not the way we treated our “customers”; this officer appears to be agitated and acting unprofessionally. But you continue to exaggerate in your description of the event. Anyone can watch the video and judge for themselves.
He didn’t pick him up and drop him hard? He didn’t sucker punch him at the end? Granted... it wasn’t much of a punch and it probably didn’t hurt, but it was an unnecessary PUNCH and could have caused injury. In no way am I exaggerating the principles involved here, and whether the guy was actually hurt or not from the encounter is completely irrelevant.
