Excellent, confirms exactly what I posted in the hearing thread. I knew it was the male intern she was laughing with.
Pretty sick behaviour in a murder trial but there you go.
I watched the hearing again and you could plainly hear them discussing TES and the searchers at the sidebar at the end of the hearing. I could plainly hear Mason saying (and I paraphrase) "there were 32 searches...but we are not talking about those ones"
Casey wrote a long note to Mason before the hearing ended, Baez was up at the podium talking at this time. In Mason's response to Casey he motioned to the bench with his finger. I'm guessing he was telling her that he would ask for a side bar to discuss the "issue" with the judge. At the end of the hearing Mason takes the piece of paper up to Baez and has a quite word with him. They both sit down and some other things are discussed then Mason flicks at the piece paper again and requests the sidebar. So it was Casey that brought up the issue and requested the sidebar. Casey is driving the "no Caylee there" when the searchers were looking, I have no doubt.
