I personally think that George has been basically "hamstrung" on the subject of Casey. I think he WANTED to be a better father and to discipline her and to make her responsible for her actions to a point and that Cindy, as ruler of the roost, would not allow that. SHE ruled Casey AND George AND Lee and nobody was going to usurp her authority. Thereby, Casey and George apparently had a somewhat antagonistic relationship, and if we recall (taken with a grain of salt of course) when Leonard P. was on the scene and George's close friend was there, it was said that HE said "That ***** in there knows where Caylee is but she is not talking"... IF in fact he did make that statement? I think it tends to reinforce the idea that all was not roses between George and Casey, and since she already holds ill will for him, it was a hop skip and a jump to this entire fiasco with the abuse, setting her up, covering up, etc. I think this is ALL her plan, and poor George is HER victim. Not the other way around.
