back with me now, defense attorneys alan dershowitz, yale glantand, and shawn holley.a quite lengthy and contentious interview with robert zimmerman, george's younger brother, the only family member speaking at the moment. i thought it was very enlightening in one way, in that i interviewed him two weeks ago and there was much more detail from him this time about what is clearly the family view of what happened. and there were definitely some contradictions there. i mean, at one stage he said that you had trayvon martin on top of his brother, with his hand over his mouth, but didn't explain how, if that's the case, how was his brother screaming out? and there were other moments like that where i felt, this doesn't work out. what did you think of it? >> well, the major contraction, i think, was in the first interview, he basically said that martin confronted him and spoke to him and said, why are you following me? in the second interview, it was a sudden attack without any speaking at all. and so, you know, there are risks involved in having anybody speak to the media o
