I find it absolutely amazing that the bulk of "evidence" is from the defendants own mouth, and yet it is being accepted as fact.
Why didn't TM have scratches or DNA on his hands if he was involved in such a "beat down" as one poster put it? How can it be considered self defense when the injuries were so minor as to not even need medical attention until the next day, belying the notion that he felt his very lfe was threatened? Why did the screams for help end at the exact moment of the gunshot? If Zimmerman was on the ground when he shot Martin who was allegedly on top beating his head in, why wasn't Martin's blood all over the front of Zimmerman?
Again, this sets a horrible precedent. I can assume you look suspicious, follow you for no reason other than my own delusions, yet if you feel threatened and confront me, I can shoot you dead and walk away free.
It's no wonder the Prosecution in their closing arguments begged the jury to use their common sense.
