George and Cindy are always wearing a Caylee shirt and when Casey is out she is always wearing one.
Why doesn't Lee ever wear one???????????
IMO Lee has never believed Casey's story. He won't turn his back on his family, but he won't wear the shirt, either.
The only way to find out what happened to Caylee is through Casey. Lee knows this and he is not going to alienate her at this point because gaining her confidence is the only chance he's got to find out what happened to Caylee.
He's playing her like a cheap fiddle, ^5's and all. JMO
