How exactly do you know Martin assaulted Z first? Did you actually read all the evidence? Martin had a bruise around his eye according to the evidence. So, is it not possible that Z hit him first, and then Martin punched him back in retaliation? See I really don't know what happened but you seem to know. So, please tell us all how and when Martin got the bruise around his eye.I don't know if Z approached him or if Z talked to him and then walked away or how that piece happened. What I do know is Martin physically assaulted Z and got what he deserved.
