Well, I wouldn't have done what Trayvon did, either. But I have to admit that if a friend told me that a guy was following him around, then got out of his car to approach him - without identifying himself, for some reason - and he socked the guy, I wouldn't blame him. I don't agree with violence, but this is a case where two individuals acted stupidly and the only difference between them was that one was going to kill the other. And what if Trayvon had rushed at Zimmerman, and then was shot? What if Trayvon reached into his pocket to get his cell phone and Zimmerman shot him? The way some arguments go, in both scenarios the "defensive shot" would have been justified. I don't think we should encourage trigger happy stupidity, that's all I'm saying. Some people have argued that Trayvon would have killed Zimmerman, but I think it's a ridiculous notion. A 17 year old going home to watch the end of a basketball game decides to kill somebody with people watching in the middle of a neighborhood? I don't think so, at least.
I don't think a guy standing in the rain is suspicious, but if a person is paranoid enough to think so, let the police handle it. The very least we can get out of this situation is a big reminder not to take the law into your own hands when it isn't absolutely necessary (or in the case, even remotely necessary).
