Again, was not saying or implying the black guy was involved in anything gang related. I only used that as an example of when a deadly armed Vs. unarmed altercations might be accepted/justified and cleared legally--particularly a case involving a teenager and adult (specifically in response to Prosthetic's earlier assertion that an unarmed 17yo could never poses a threat to an adult). Please read the entire discussion before you take comments out of context.
Some people seem to be under the mistaken impression that deadly armed Vs. unarmed cases should always result in an immediate arrest and conviction--no they shouldn't. Maybe this guy's a racist, maybe he's not. From what I gather there's not enough public evidence to (fairly) say one way or the other--though a lot of people seem happy to give him the chair based solely on their assumptions and prejudices. Yes I said prejudice, racism and stereotyping are a two way street. A lot of hypocrites in here seem all to happy to assume this white guy was a bigot out to purge his neighborhood of minorities-- just as he was (supposedly) assuming minorities were out to murder, rape, and pillage his neighborhood. No on all accounts. You're no better than the guy your condemning.
Personally, I think there are only a few potential ways this case played out:
A) This guy was honestly just trying to keep an eye on his neighborhood and would followed and approached any unrecognized individual out for a stroll at this time (be they white, black, brown, yellow, young, old, or crippled). Supposing that, it seems unlikely he would have approached this individual threateningly--banishing a gun or tossing slurs and epithets. In such a case, the "victim" would have had to have been the aggressor--perhaps taking offense to being following, playing the race card out of nowhere, and/or threatening/starting physical violence which eventually resulted in the shooting.
B) This guy was a Grade A racist fuck who happened to spot a black kid prowling his neighborhood, followed him, and approached him in an obviously threatening/condescending/racist manner. Threw the first punch, and ultimately pulled the gun and shot him.
C) Some combination of A and B.
It really sad to see so many people convinced it's scenario B with so little apparent evidence.
