That's a terrible argument. What actually happened was a felony because it involved a serious bodily injury. You don't get to pretend that felony assault is anything close to misdemeanor assault because it's not. Hubbard got a stiffer sentence because firearms require it. Lattimer got a felony because he put his victim in the hospital with a host of injuries that were individually enough for a felony charge. Clayborn could have been charged with a felony, but he stopped after injuring the victim. Lattimer decided he should body slam the guy a few times after knocking him out. Not quite the same thing.
What a saint.
