He sure is. What I got from this interview was Robert's last comment. There is a witness who saw the whole thing from the first blow. I'll bet that therein lies the main reason George was never arrested or charged.
I went and looked at the transcripts. Man, Marcia Clark is another piece of work, here. There was an interview of another eyewitness. Marcia said, afterward ...
But the fact that George Zimmerman stood up, walked away with no apparent difficulty, no apparent bleeding, seems to fly in the face of the indications in the police report that he was -- that he said he was -- his nose was broken, his head was beaten in. Yes, there may have been some minor injuries due to the scuffle, but what's being described by this witness indicates it was no major struggle. Very likely the one who was crying for help was Trayvon. Very likely the one who was being pinned down was Trayvon. And the fact that this witness said that Trayvon Martin was face down when George Zimmerman stood up is another indication that it was George Zimmerman who did the attacking and that it was a scuffle initiated by him and ended by him.Anderson Cooper - Aired March 29, 2012
ZIMMERMAN: Well, the eyewitness that was there actually saw -- I don't think his face has been revealed. I know that the police have his testimony. I know that media in Florida have gone to his house and he doesn't want to open the door, but he did apparently see the whole thing from the first blow.Piers Morgan - Aired March 29, 2012
There's lots more in that interview - in particular that Zimmerman was being disarmed, and what Zimmerman says Trayvon was remarking during the fight ...
what Trayvon said was, either to the effect of, I believe, this is going to be easy, you die tonight or you have a piece, you die tonight. And then attempted to disarm him.
The nature of the disarming attempt is also alluded to, and it is NOT trying to take the gun from Zimmerman after Zimmerman drew it.
