Quote from PiggyBank:
1) Does it occur to you that treyvons hands may not have been on his mouth the whole time? You realize they were in a fight, moving and squirming, don't you?
2/3) When he got shot he fell on his face with his hands under him, and the grass was wet, it is possible that the water washed the blood off. Also, unlike movies, punching someone doesn't automatically hurt your hands or make them swell up. Also cause zimmerman was on his back, the blood from his nose might have been running down his throat until he stood up, as his lawyer pointed out.
4) You simply can't accept or don't understand the facts. I wasn't sold on zims story until i watched the opening arguments. West broke it down in detail while the prosecutor just tried to use emotion and a few discrepancies to make his case. Assuming every FACT the defense stated is accurate, which is not a very big assumption, not only is zimmerman not guilty of murder, he seems to have done nothing wrong. Treyvon was a kid and imo, he didn't deserve to die but the evidence suggests that he put himself in that situation and that was the outcome.
