except that he beat up zimmerman for no reason,
Um, if I chase you two blocks thru the night, that is kinda a reason for you to punch me in the face.
If it happned at the truck, yes, that's no reason. But he was creepin, dude. Zimm was justified in shooting trayvon once on the ground - but trayvon attacking for NO REASON? A mfer was following him, chasing his ass. that's a reason. Be reasonable, dude.
