1. Who cares? The police knew he was causing trouble, and he didn't listen when they tried to stop them.
2. Definitely who cares? I'm concerned for the people of my community. I don't stalk you, do I?
3. Then if Treyvon was a suspect in them, he should have been duly investigated and tried for them, as per the law.
4. And if a duly authorized police officer had been suspicious of him, that would matter.
5. I don't really care about the actions in the fight. Why is only the vigilante allowed to fight for his life? Even when he created the danger to begin with.
6. Same question.
7. Speculation. If he wasn't being stalked, he'd still be alive, too. If he hadn't dared leave his home in the first place, he'd still be alive. He'd be alive in any situation other than being stalked and murdered by a vigilante.
8. See 5 and 6.
9. See 3.
None of your minutiae about a fight matters at all. The mere presence of a black youth was deemed suspicious, and he was killed for the brazen act of walking down the street. He should never have been hassled or stalked by a vigilante in the first place. You don't get to claim self-defense when you create the danger in the first place. If he'd gone home when the police told him to, no one would be dead from this.
The message from this situation was the vindication of vigilantism, and the murder of "suspicious" looking people. Fantastic precedents to set, aren't they?
