Like the lawyers telling me to not to talk to my child about the case of my missing grandchild that went missing on her watch would carry any weight. I would be on her every waking minute and waking her up every hour on the hour to ask the same question "Where is Caylee?"
This is where you have to decide what your priorities are, finding Caylee or protecting your daughter or keeping the blinders on so you can continue to live in fantasy land.
Lawyer be damned, someone has to ask her the tough questions, why not her parents? They can always get the info then pretend that they didn't and come up with some cover story and still find Caylee's body. It is not like they don't know how to lie.
