I never thought the state had a case in the first place. All we hear on the news is about how he "shot an unarmed child".
Trayvon Martin was justified in being edgy at being followed. Absolutely. But he was the one who assaulted Zimmerman. He gets in George's face--understandably--but then when George foolishly takes his eyes off the guy to reach for his cell phone, Martin sucker punches him and proceeds to wipe up the concrete with him.
That's hardcore assault anywhere in the world. Had he succeeded in killing Martin, and any time you slam a guy's skull on the concrete that is a possible outcome, it would have been Martin on trial for 2nd degree murder--with a lot more cause than the prosecution had in Zimmerman's case.
It leaves me shaking my head in disgust, and not at Zimmerman. George was an idiot for following Trayvon like he did. There's no way he should have done that. Granted. But under the law, one has to look at the proximate cause of the whole mess, and in this case, that was a six-foot, athletic 17 year old with obvious martial arts skills sucker punching a lard bag like George, and then going to ground and pound on the sidewalk.
Travyon Martin was the one in kill mode, and had George Zimmerman not been armed, the odds were he (Zimmerman) would have been beaten to death on the spot.
