Because clearly Travyon didn't punch George, as has been previously stated as fact, nor did he likely "slam" Geroge's head into the concrete, based on George's lack of severe head injuries! So why else did Travyon have to die, because George wanted to get a black man???
I won't say he wanted to get a black boy, but I will say IMHO he was a trigger happy "wanna be" cop with an out of control EGO...JMHO
