I think it's unfair to say Tony liked the media crowd coming in, etc. He hasn't done anything wrong. He didn't kill Caylee. He didn't sell his story. He hasn't been actively seeking the media, even though he is trying to break into the entertainment business on some level. In fact, he says he changed his number because of harassment.
I also think it's unfair to say he is cocky. For all we know, he is embarrassed and angry about being forced into this position, having people constantly ask, know his name, etc when he's trying to work, study, and build a life for himself. Maybe his "flip" answers are just years of pent up resentment coming out, since he was thrust into the limelight.
I think he is doing as well as he possibly can, and we need to remember that he is a witness, not a suspect. I feel bad for him!
Just my two cents.
