Quote from IShopAtPublix:
If Zimmerman wanted to murder the kid, you walk up and unload one shot to the head or the whole clip. The whole thing is inconsistent with murder. There is at least one witness who said on record that it was treyvon on top of Zimmerman and zimmerman pleading for help. That is the whole ball game. Reasonable doubt overflowing from there.
Never mentioned first degree murder, premeditated or anything like that. Just doing something stupid, and using a gun. If there were 20 kids carrying off stolen items, I doubt he would have confronted them, being scared to death. But one kid walking home, no problem.
