I don't think she is someone who is going to confess. As matters stand, there is a limit to how much time she will have to spend in prison if she is convicted of the charges against her. She won't incriminate herself on murder charges or help LE gather evidence against her -- why would she? Better for her to take her chances that LE won't find evidence on their own to charge/convict her. I haven't seen any guilt or even real worry about her daughter. After all the bad publicity, she seems to be trying to conform her conduct to some degree of acceptability, but it rings false with most people now. She's too strongly disliked to ever get a break.
I was amazed on reading the search warrant affidavit at her degree of audacity and cunning, right in the faces of LE. Can you see yourself calmly taking them to your fake place of employment, telling the security guard you lost your ID, striding purposefully down the hallway to your office, before the 12th hour "oops, I lied." I think she's still working a plan in her own mind, and have no idea whether she feels she is succeeding. She's put a lot of time and distance between herself and Caylee and any evidence of what happened. There was probably more to come, but unfortunately, nobody stole the car from the parking lot, with her handbag and the car seat, etc. in it. If so, those would be gone and the owners of the lot wouldn't have had it towed. That led to her family locating her and starting the search for Caylee. Sorry about how long this is! Oops. But not feeling so hopeful she will EVER help.
