George has said he didn't think he and Cindy would be together when all was said and done. To me, this says that the arguing could be because they can not agree on how to "help" Casey. Could it be, George will tell the truth on the stand, ultimately defying and rebelling against Cindy, no longer doing what is expected of him from his wife?
In his police interviews, he was honest about the smell in the trunk. He told them he believed in his heart, Casey was going to be going away for sometime, as well as spoke of Caylee in the past tense. I think he felt secure to open up to LE. For one, his wife was not there to butt in and glare at him. Secondly, they were men. Law enforcing, men that he respected.
Once that tape was released, I am sure he felt the wrath of Cindy and possibly from his son Lee...
Watching that interview, there was no painful frown while boldly lying/defiantly sticking out his chin because these were his real feelings. George was actually allowed to talk in private for once and have his own opinions/theories. It sounded to me as if he was really trying to help them and (maybe not so much outwardly verbally) assure them that Casey was where she belonged.
Remember, there had been some tension between Casey and George for some time at this point, I believe one of the first stages of grief for George, very well could have been relief that someone was finally doing something about their problem child.
Shortly after, he seemed to have gone through a phase of anger. Whether it was at himself for yet again, bowing down to Cindy, for being so honest with LE and having been exposed (mostly Cindy finding out) or not doing more to prevent Casey unleashing on Caylee, at Casey for taking away his beautiful grand daughter, who knows.
Probably a little of all of that.
Something else I have noticed about George is when he saw Cindy get out of control at the depos, he seemed to snap out of it, tell her to shut up and yet again become apologetic for his wife (same as when the car was repo'd, with Le etc.).
He, like all of us, definitely struggles with his own demons and the decisions he has made in life.
I want to also be clear that in no way did I post that picture to defend George, or say that I agree with the shady things he has done.
I posted it because that picture broke my heart, and as pointed out, this is the only display of raw emotion we have really seen come out of the A clan for sweet little Caylee. (If Lee's speech was for Caylee at her "memorial", well, he should have said so. In my opinion, that was for Casey.)
I do not wish to speak badly about him because George Anthony will live out the rest of his life in his own hell.
What goes around comes around.
It is never too late to do the right thing.
