Seriously! I agree with you. You can see CA trying so hard to get information but not really wanting to hear the truth because she knows something is wrong.
She tries to trap casey regarding the supposed picture in Zanny's apartment, but then she realizes she does not really want to hear another lie from casey, so she tells casey, "I know who's apartment it is", before casey can lie. She tries to get casey to look in her eyes. "You know I have to do that." she says. CA is trying to see if casey is being truthful and casey cries when confronted in this way, which immediately causes CA to go into protective, comforting mother role "It's ok to cry, casey."
You also hear CA directly ask casey, "Are we going to be able to find her? Everyone is looking for her. The whole world is looking for her, casey. Are we going to be able to find her?" She is asking her then, if Caylee is dead and buried, or not. Come on! To me it is obvious that CA does not know the truth (or has not accepted the obvious), and is torn between not trusting her child, and wanting to badly to be able to.
As far as the comment about forgiving casey for anything she has said, the reason casey pulls the phone away from her like that is because it is pretty much the first thing CA says on the phone and casey exclaims that the sound is way too loud and asks a jail person to turn down the sound. Did everyone just miss that part? There follows several second about the loud volume.
I agree with an earlier poster that the comment may have been in reference to anything casey said to the doctor during the eval.
I think CA and the rest of the family have either consciously or subconciously covered the total truth, in order to protect casey and protect themselves from the reality of who casey is and what she has done to Caylee. But, I really do not believe there has been anything so egregious as moving a body, or helping to dispose of the body, or participating in the murder. Other things, yes. Enough for obstruction? With FL laws, perhaps. Just doing a parallel investigation and questioning witnesses may be enough. Hiding evidence is definitely enough! So may be not telling all they know or lying about certain things. I'm thinking of handing over the wrong hairbrush, washing clothes from the car and telling LE that the night of June 15 was a wonderful night in which CA tucked in Caylee and casey for the night, as if casey was 12 years old.
Some of these things are bad enough, but I just don't think the Anthony family's hands are anymore dirty than that.
