Zimmerman was not "attacked." He was stalking Martin and killed him deliberately. The little bitch thought he was Rambo and murdered someone, but he was so scared to go to the grocery store that he took a loaded gun with him. Pathetic.
Good Lord! Please educate yourself before you state things as 'fact'.
Pathologist supports Zimmerman's description of attack
2 Witnesses Say Zimmerman Was Beaten
Zimmerman was a 'Action Hero' / 'Cop-Wannabe' who overzealously pursued someone in his neighborhood who should not have been there / did not live there. He called the cops, as he was taught by the Police to Neighborhood Watch Members. THEN he continued to 'stalk' Martin.
Martin hid, understandably, and watched Martin from his hiding spot. Assessing that Zimmerman was alone, and a creepy cracker' as he told his girlfriend, he decided to confront Zimmerman - also what he told his girlfriend he was going to do. In several accounts / reports Martin supposedly told his girlfriend he was going to 'teach this cracker a lesson' (Intent to Confront).
At this point both Zimmerman and Martin are in the wrong.
Zimmerman and witness accounts, that later were confirmed to contribute to the 'Not guilty verdict' of Zimmerman, proved Martin physically assaulted Zimmerman. In self-defense, the jury found later, Zimmerman used his weapon and shot and killed Martin.
This was a NEEDLESS shooting / murder. The fault lies with both of them.
The media rushed to make this a 'white racist kills black' story, before finding out Z was a minority as well.
IMO 'race' played a part, as Z saw a black male wearing a 'hoodie' in his neighborhood where he did not belong 'acting suspiciously'. From that point on STUPIDITY played more of a part for Z than anything else. Martin made a bad choice to confront Z, especially if he sought to 'teach him a lesson'.
WHAT would have prevented this:
1. Z backing down after he called the police.
2. Martin coming out (especially if he was not doing anything wrong) yet keeping a 'distance' between himself and Z if he thought Z was a 'creepy guy' who might mean him harm.
3. TALKING: Z asking Martin what he was doing there. Martin telling Z what he was doing there.
