Yes, I agree with you that we probably don't have the whole story, but what she did say seems to me to support that Trayvon started the fight. If Z was planning on shooting Trayvon, why would he get so close? And since he knew the cops were coming, why would he initiate a brawl? Doesn't make sense to me. What makes more sense is that Trayvon felt dissed about being challenged for being there and sucker punched Z when Z went for his phone. Trayvon may have thought Z was going for a weapon. Tragic case all around.
Since we know that the media is fanning the flames, it's entirely possible that the police have a more complete statement from the GF than what the media showed, especially since the Martin attorney was present for the interview.
Of course there could have been an argument going on between TM and his GF and she could have been hung up on just prior to the "brawl".
I can see it now, Trayvon walking along with his cell phone in hand connected to him by a headset of some sort while talking to his girlfriend as he approaches Zimmerman and begins to argue. Now, I am in my 60's and a bit clumsy to boot. I've walked into my share of doors, walls, poles and such while talking on the phone. Yes, my headset, both wired and unwired, popped out of my ear on many of those occasions. And I quickly learned the phone was still on and I could put the headset back in my ear, apologize to the person on the other end and keep talking. So, as someone a week or so ago remarked, how did that headset (and attached phone) get turned off when the brawl/fight/beating started?????
My thoughts are that the phone was either on and she heard more than is being provided or it was off and she heard nothing whatsoever.
