In response to ComingLiberalCrackup's comment:
"maybe that confrontation led to zimmerman getting beat up by a 17 year old kid? does that give him the right to murder the kid? no."
So if Trayvon Martin was on top of Zimmerman, viciously beating his head against the pavement and also breaking his nose, then Zimmerman has no right to pull his weapon to save his own life?
You clearly have already made your mind up, that it was a racist act against an innocent kid, it fits your predetermined template.
If Martin looked suspicious to Zimmerman because he was walking in and out of buildings in the rain, how do you think Zimmerman looked to Martin? If Zimmerman was justified in following Martin, then Martin was justified in attacking Zimmerman. Beating him senseless was lawful, according to Florida's 'stand your ground' law.
I'd have a hard time finding Zimmerman guilty of murder, because I don't think this is what he intended to happen, but he can't dodge all accountability here - his actions are responsible for Martin's death.
