Dude, you have no idea whose screams those are in the background of a muffled 911 dispatcher record. Like, you used *that* as obvious evidence of what took place? All kinds of shit goes down in a fight, it's not some clean execution where Zimmerman had the kid on the ground at gun point pleading for his life then shot him.
No.
Ok, I think the Zimmerman guy is guilty, and I hope he is convicted. But that's not really my point. My point is this is not wild conjecture, this is pointing out that there is much, much more gray area than people are pretending.
