Probably very unpopular here after I say this but, I believe Lee is trying to tell the truth. I think that he believes one thing in his mind and another in his heart. After he made the statement that "i believe everything my sister tells me" he then admitted later that he had to believe that. He might initially believe what she says, until it is proven incorrect. My son, happens to have a nervous laugh like Lee's and I believe it is a nervous laugh. My son laughs like that for two reasons - he is nervous, or he is telling a half-truth. He has never told me a bold faced lie, he is not comfortable doing that. He always tell at least half truth and then laughs after that. He is a great kid, just has an issue with being on the spot. I would not want to be in Lee's shoes. At all. He wanted the truth, and there are things that he heard that I am wondering whether he even told his parents. Again, probably not going to be popular, but please, he testified there for three hours. How easy can it be to do that?
