I don't have much luck posting photos or I would post it here. He wasn't some skinny lil kid.
If it were MY son, he’d have broken his knee-cap, then his wrist, then kicked him in the back of the skull because that’s how I’ve trained him (6’2 250 starting nose tackle on varsity) to handle an armed attacker who accosts him without a badge or other show of authority
(kick to the knee put him on the ground quickly, joint lock to the wrist as he goes down, head-kick to make sure he doesn’t get back up)
Zimmerman started it, Martin had a right to fight back
