From the testimony I've seen Treyvon's girlfriend give, I think things are going very well for ZImmerman right now lol..... the prosecution probably had a hard time watching that stuff. It's a really sticky case, it's almost impossible to tell what really happened when there when nobody saw the full altercation... it's tough to call either way, but my gut feeling, I think Zimmerman was just a guy that genuinely wanted to keep his neighborhood safe, and followed a kid, and the whole situation just got really really out of hand. Can totally see how some would think otherwise though.
It's hard to really say much of anything, this case revolves around race and/or racism at it's very core.
I'd say the defensive is far and away winning right now.
