There is strong physical evidence of Martin hitting Zimmerman and slamming his head to the ground. Zimmerman had a broken nose and cuts on the back of hand while Martin had abrasions on his knuckles. There was an eyewitness he saw martin on top of Zimmerman beating him with repeated punches. There is no evidence either physical or from witness the Zimmerman ever struck Martin with anything besides a bullet. Martin was thirty seconds from his fathers home yet the fight started four minutes after that. Sounds like martin circled back just like Zimmerman claims.
Despite you using all caps for the word fact there is zero evidence that Zimmerman confronted Martin. Sorry I know you may have been mislead by the race baiting morons who populate the airwaves but stand your ground really doesn't mean you can turn and beat the shit out of someone you think is following you. It isn't self defense to attack someone who is following you it is assault.
As for how innocent Martin was there is no reason (well outside of the need to call it profiling) that Martin was not behaving as oddly as Zimmerman claimed in his 9-11 call and Martin dis have a history of violence and he had been caught at school with burglary tools and stolen items. So sorry the claim that it is a FACT the Martin was innocently walking home is not support be any actual evidence
Funny how no one got upset when a black man was acquitted in NY for shooting a white teenager who he confronted for breaking into cars and then shot twice when the kid lunged at him. But then again that case didn't support the world view of the talking heads and the sheep who follow them so it wasn't important, you know sort of like the actual facts in the Zimmerman case. You do not need actual facts when you know the real FACTS.
