The "chase" with all the screaming and shouting may have been Zimmerman fleeing as he was being attacked by Martin. Martin's own father said it was not Martin crying for help. Zimmerman tried to retreat but was overcome by the younger, faster, stronger Martin. Martin scratched his hand in his assault on Zimmerman, the only wound other than the gunshot wound. Zimmerman had multiple injuries, consistent with being assaulted. Your attempts to cloud the facts by attaching inflammatory and inappropriate labels such as "chase","innocent child","profiling","fairness","social justice", blah, blah influence no one but other simplistic ideologues as your self. go cry in your corn flakes.
