There were also witnesses which saw the two scuffling on the ground and witnesses who saw GZ on top of Trayvon. No one saw the initial assault. Zimmerman says TM attacked him but he could have grabbed Trayvon to detain him and Trayvon fought back.
I told my daughter at that age to run away if she saw someone following her (which Travyon did) and if that person caught her to fight with all she had because the statistics show that if you are abducted, you are overwhelming likely to be killed. I told her to make her stand and not allow herself to be dragged into a car. My scenario of a frightened Trayvon defending himself seems more likely to me given that Trayvon ran away from GZ and TM's girlfriend says he told her that he was being followed by a suspicious person. Zimmerman's scenario has Trayvon running away and then changing his mind and wanting to fight where as GZ showed consistent concern that the 'suspicious' TM would get away. If you believe the girlfriend (I do), then she heard the first part of the confrontation in which TM asked "Why are you following me?" and GZ answered "Why are you here?" which doesn't sound like Martin had been sneaking up behind George which would have been hard to do since he was talking to the girlfriend the whole time, as confirmed by cell phone records. I believe it was about a minute later that Zimmerman shot TM.
By the way, this is my first post here! I am so glad to find a civil discussion florum.
