re: "Its been nearly a MONTH & Zimmerman hasn't been arrested for killing a 17 year old teen carring/armed with skittles & an iced tea."
In America, the police don't arrest people when there's insufficient evidence. Well, not in the America *I* know. But America is rapidly changing, and I wouldn't be surprised if political pressure mounts to have Zimmerman arrested even when the police obviously don't think they have enough to go on.
re: "What if the teen was YOUR son?"
If it were my son, I would be heartbroken, and (of course) I'd be upset that Zimmerman hadn't been arrested. I know my son well enough to know that he wouldn't attack someone. But I DON'T know anything about Trayvor Martin. Nor do I know much about George Zimmerman. So, I'm not going to be quick to judge.
BTW, my sister was murdered. No arrest was made even though we all knew who did it. I'm not so stupid as to blame the police for that. The evidence just wasn't there.
