You're another passive aggressive Zimmerman supporter. Trayvon bashing Zimmerman's head against the concrete has not been proven. The medical expert that testified said that the cuts/scrapes to the back of his head were minor and were caused by one hit against the concrete. Again, it hast been proven that the 1 hit was from Trayvon bashing his head. The problem with you Zimmerman sympathizes is that you keep assuming that Zimmerman's story is true despite the inconsistencies.
The 911 call that Zimmerman made is proof that he acted with ill will and a depraved mind. He profiled Martin "this guy just looks like he's up to no good, he followed him(carrying a loaded gun) with the intent of not letting the "suspect" as he called Trayvon, get away. He follows Martin instigating a confrontation, yet he then refuses to identify himself as some type of neighborhood watch guy who's just concerned about the neighborhood. Zimmerman even claims that Trayvon asked him what was up, so we know that he had the chance to do so. He had ill will toward Trayvon the second that he saw him, profiled him as a criminal based on his appearance, and decided to follow him and not let him "get away". Again, even Zimmerman said that Trayvon tried to run away.
Zimmerman's nose wasn't broken, it was just swollen. If he had a broken nose then he wouldve went to the hospital that night. While its true that not all fights result in excessive bruising and bleeding, Zimmerman claims that he was in a fight for his life. He claims that Trayvon was bashing his head against the concrete repeatedly, but that's not supported by his injuries. He also claims that Trayvon was attempting to smother him with his hands, but the fact that there wasn't any Zimmerman DNA on Trayvon's doesn't support that claim either. How could there be no Zimmerman DNA on Martin's hands if he was indeed beating Zimmerman down with punches and trying to smother him by covering his mouth/nose? This is why you can't just take Zimmerman's word, the evidence doesn't support his version of the story.
Proving that he had a depraved mind is necessary for the murder 2 conviction. He could still be convicted of manslaughter without the jury thinking that he acted with a depraved mind. If you claim self defense after killing someone then you have a burden as a defendant. You can't just kill someone in a situation where there aren't witnesses and dare the police to prove you wrong. Zimmerman has yet to provide any evidence that Trayvon attacked him first, all he has is his word and he probably won't be willing to testify to that in front of the jury. Trayvon being on top of Zimmerman at some point of their scuffle does not prove that Trayvon attacked first. The 911 call is strong evidence that Zimmerman wasn't acting in self defense because it paints him as the instigator of their confrontation. Zimmerman's team have to present a reasonable scenario that illustrates that Trayvon some how flipped the script and attacked Zimmerman 1st despite the evidence that shows that Zimmerman was following Martin as he attempted to get away. So far they have not done it.
Well you obviously came into this pro-Zimmerman. None of the witnesses saw anything except the aftermath. Even the guy who claims to have saw Trayvon top, didn't see Trayvon throwing any punches ad he didn't see Martin bashing his head against the concrete. Again, the 911 call paints the picture of what happened for you. Zimmerman, profiled, followed, and eventually killed Martin. How anyone can listen to that 911 call and just assume that Zimmerman's claim of self defense is valid because he said so is beyond me.
