Any juror finding against Zimmerman needs to have their head banged into the sidewalk.
Then ask them whether they believe it is legal for them to stop the assailant.
Zimmerman saw Martin casing an apartment and was told by the police dispatcher to keep an eye on him. Because he did so, Martin attacked and tried to kill him.
All Zimmerman has to do to show that he was not motivated by Martin's race is to prove that he would have behaved the same way if Martin had been white.
