You can not say in an actual argument that LE has anything; just like he can't. You haven't seen it, so all you know is media hype and leaks (from LE as well). This is what the man is saying.
Besides all the other stuff, if his defense is based on a living Caylee (which at this point I think would be stupid, since there's SO MUCH EVIDENCE SAYING OTHERWISE </sarcasm>) he would have to produce Caylee, which he can't do, as he just said, 'cause KC doesn't know where she is.
Damned if you do, damned if you don't. He's doing the best with what he has to work with. Everyone in this thread saying he's a joke has obviously never been to court, let alone had to get an attorney. There still has yet to be a person on this board that has a law degree or is studying for one that has disagreed with me: words are words, fact is in front of a judge.
