If he walks, its cause the jury was never going to convict regardless of how good a job people think the state was doing.
That's where I've been leaning. The Jury is pretty much white (not counting the Spanish mix - she's probably a ring-tailed tree dweller as well) and coming from that community they all think blacks are guilty of everything under the sun. True it's early in the case but like others have stated it only takes "ONE" to disagree and Zimmerman the cunt walks....
