Its all in the autopsy and medical reports and witness statements. Trayvon's bloody knuckles and the injuries to Zimmerman's head tell us who the thug was.
When you have genuine proof that martin started the fight and acted thuggish (instead of running away - as zimmereman said) then post it.
Until then you too are just babbling.
No one saw what intigated the interaction, witness saw tow man fighting on the ground. Isn’t it hust possible that zimmerman shoved or pushed Martin initially? The reality is that we will never know what happened. Zimmerman is no hero.
