How do the laws regarding use of force go in the states(or England for that matter), was the trucker within his rights to knock him down, out & continue pummelling?
Over here the moment you get the assailant down and he stops swinging at you, if you throw a punch it counts as an assault instead of self-defence, making you equally guilty in the eyes of the law. Or, in this case when the trucker's obviously bigger and stronger, he would be more guilty
