Ok, I'm gonna go out on a limb and say I feel sorry for CA. In my opinion, she doesn't want Caylee dead and she is doing whatever she can to hold on to that hope. Casey is the only one that offers her that hope so she in hanging onto her. In a way I kinda get her. She isn't saying she doesn't believe the evidence, she is just saying it's no enough proof for her. She has no body and no on is coming out conculsively and saying she is dead, with in evidence she wants to see. So far it's been a lot of leaks but no press conference and no documentation. She wants to be over to go over the evidence herself and short of that she wants to believe her granddaughter is alive. I can't say I blame her. I know, and most know that Caylee is dead, but that isn't my granddaughter and she wants to hold on to that hope. Because not only does she have to accept that Caylee is dead, but she has to accept that her daughter is responsible and she has been lying (HELLO?) and letting her suffer all this time. She just can't process that at this time. Hopefully they will find her body, or present concrete evidence and she will be forced to accept it. Or reject it and continue living in her hopes and dreams. She needs to believe Casey because to alternative is unbearable to her.
