by august 14, she'd been isolated from her family for a couple weeks, her lawyer telling her not to talk to anyone, including family. she wasn't supposed to even take that meeting. she knew by now that they record everything and release it to the media. her lawyer is her only source of information as to how things are going and her parents only want to try to get her to talk about something she has been instructed NOT to talk about. yeah, it's the information her family needed to find Caylee, but she'd been told not to speak. casey does nothing so well as obey and blend into the new person in her life and if jose told her to keep her mouth shut, that was what she was going to do, even if it 'frushtrated' her that it was all her parents wanted to talk about. in my opinion, they skated just this side of interfering with her right to an attorney by attempting to subtly coerce her away from jose. (i'm not saying that would be a bad thing; i just wonder how legal that was.)
and i am quite aware that her parents were earnest about finding Caylee. but i'm also aware that the dynamics of the family was always a much bigger priority in that family and it was taking front and center on august 14. casey wanted them to listen, and they wanted what they wanted regardless. yes, the goal was important. she explained why she couldn't answer those questions from where she sat.
