Trayvon attempted to remove himself from the altercation. George chose to continue it. At the end of the day, George shot and killed an unarmed teenager.
There is no getting around that, and that's the huge problem George and his fan club have to contend with. You guys can compose whatever "attack" theories you want, but it doesn't change anything.
Trayvon was unarmed. He was where he had a right to be. He was doing nothing wrong. He attempted to flee from Geroge, George chose to follow. Whatever happens after that is on George. George was asked if he was following, and told "we don't need you to do that". George was well aware of his responsibilities as a NW member; specifically not to engage with suspicious persons, but to call law enforcement.
You and the other George fans can spin this as much as you want.
All we have is George's multiple stories filled with ionconsistencies, physical impossibilities and self-serving dialogue. See, the unarmed teenager that was doing nothing wrong and had a right to be where he was (and attempted to remove himself from George and the altercation) is dead.
