It was unlikely that we'd see a conviction in any case, given that the jury members were all white and hispanic, in a racially-charged case. Maybe I'm just too cynical, but I never saw much hope of Zimmerman going down. This is just too reminiscent of last-century cases for me to not expect the worst.
Funny, there are people saying a conviction is inevitable for the exact same reason. The defense and the prosecution both had to agree on the jury picked, so it's going to be down to the facts. For the best.
Zimmerman isn't going to be convicted. Any ambiguity in the chain of events is pretty much covered by the area's "Stand Your Ground" laws. And that, more than anything, is what this case is about.
Morally, he is quite clearly guilty: he, a complete stranger, follows a kid walking down the sidewalk. He told dispatchers specifically what he was doing, and they told him specifically to stay in his car and not confront the kid. He gets out of his car, and confronts the kid.
Quite naturally, a fight ensues; who threw the first punch is irrelevant, as Zimmerman is quite clearly in the wrong at this point. By that I mean this: if you're a kid, and some stranger is stalking you in a car at night, he gets out, and comes up to you, the correct response is either: GTFO or if that's not possible, incapacitate then GTFO. Zimmerman had a car, and was confrontational, making the first option less likely. And if his gun was visible, it rules it out immediate flight entirely.
Under the Stand Your Ground law though? The prosecutor won't be able to make anything stick. Even with all evidence stating that Zimmerman followed the kid, provoked a fight, and even if it showed he started the fight, that's all irrelevant. The only justification he needed was "feeling his life was in danger." The prosecution literally needs to prove that Zimmerman did not feel his life was in danger. That's the standard of evidence they need to meet under Stand Your Ground laws. Much more than race, this case is about those laws and the terrible effect they have: that they allow people to quite literally get away with murder so long as they start a fight and the other person actually fights back.
And if we look at it from the other angle, Trayvon was also quite clearly in the right. In such a situation, any kid should feel their life in in danger, because the whole 'stranger danger' thing is pretty much the second thing kids are taught, just after "Don't touch the stovetop." Based on the same and similar laws to the Stand Your Ground laws, Trayvon was legally in the right even if he did swing first. He was authorized to use any means, up to and including lethal, to defend his life. And shit like this is the result: someone died because Stand Your Ground laws only take situations and escalate them to the point where someone will end up dead.
