@thetrueone - The legal lines have been skewed in the US about when deadly force is justified. It doesn't necessarily matter if Trayvon was carrying a weapon, will a jury believe that Zimmerman had reason to believe his life, his property, or that of his neighbor was in jeopardy? The victim is dead and can't testify. At this point it appears the couple of eyewitnesses saw Trayvon on top of Zimmerman hitting him, which corroborates Zimmerman's story. If I get in a fight in a bar, with loads of witnesses, generally someone is going to step in and stop the fight before I'm beat to death. On a dark night on the side of the road, I'm not assured of that and would fear for my life if I'm on the business end of two fists and a big guy on top of me.
Those are the types of questions the jury will have to consider. Not so much if Trayvon was carrying a weapon, but if Zimmerman was reasonable in fearing for his life given the circumstances. I'm not trying to justify what Zimmerman did, he obviously brought this on himself, and this is a case of good intentions paving the path to hell. The fact that he disregarded the 911 advice and acted stupidly will work against him even though it isn't legally binding. But I'm not sure that an unbiased jury will convict him of murder with the currently known eyewitness accounts, and the current law. Of course at trial, new information held back by the police may come out and change things. I'm just going off of what we've heard so far in the media.
