Then why were they openly talking about getting a lawyer to take custody away from her biological mother and grant legal guardianship to them? This is not something that grandparents do lightly or without a strong reason. One of CA's early lines to KC was the very simple cry of "What did you do?!?!" I will go so far as to say that they did not expect Caylee to come to direct harm in this manner. But neglect and its resulting dangers they fully expected. It is just the sort of thing that a personality such as CA will never ever admit to anyone else.
As far as CA not wanting anyone else to be falsely accused... ummm wha? :waitasec: No really! That's all CA has done since aboyt 48 hours into this whole thing (pretty much the moment when she truly did realize what was going on, you can see the change in her and her stories of you go back through the tapes and transcripts.) She has outright accused Amy, Jesse, his father, Zanny, Ricardo, Tony, the list goes on and on and on. These are her direct words, recorded on tapes, in e-mails, in transcripts and depositions. She will accuse any living breathing person on this planet before she will accuse KC. Because in her messed up mind, accusing LC equals accusing herself. There is no mental seperation between the two. KC is simply an extension of CA's will and dominance. That has been the root problem all along, and that ultimately is what led to this tragedy.
