I personally believe that Lee is the most sneaky of the family (after FCA of course). He has blown kissies, said 'I love you' and given testimony that directly called his parents version into question.
He refused to talk to the SA, met with the DT and tailored his testimony to do max damage to GA (who he knew was under the wheels of the bus).
He is the only one that FCA is considering meeting up with after her release.
He gave far too much info about grannys dog on the stand (recall the ice-cold comment) for it to be truth, and I have no doubt that it was HE who ran to the DT with the pet burial tales, complete with duct tape.
I have no time for Lee, along with the rest of that family, oh and the cost of those gifts for a fairly small (and living off the State) family, suggests he's hoping his sis helps him out with some of those interview funds. (okay, gonna stop now, because this portion was just petty)
