Back to the choice of language:
KC's first statement to police. She did not identify herself as I when she was giving the events of the day. Instead of saying "I called Zanny on her phone and got no answer.", she says something like "Knocked on the door. No answer. Called Zanny. Phone disconnected." Hmm. Just like in the examples in the argument.
LA, in his first recorded statement tells LE that Caylee "was almost there" when referring to her potty training. Instead of saying, "she is almost potty trained". Hmmm.
That child. The child. The little girl. All are examples of removing the person. "KC loves that child!", instead of "KC loves Caylee."
The article also includes the fact that when someone is not be truthful, there will be extraneous details in the telling of the story. Hmm. Well, we have that here in all of the statements by the family.
So, the point is that LE knows they are all hiding something, none are telling the whole truth and all have knowledge of facts that they do not want LE to know. Lee does not want to admit that he thinks KC killed Caylee, nor does GA or CA. They want to remain loyal to their "family" the family that things like this just can not happen to.
I think CA feels that if Caylee is dead, she has no reason to continue to live. She is not fighting so much for KC, but for herself.
