I know and didn't Casey even say to George and Cindy, or maybe it was just George, in one of the prison visits, "This isn't teaching me anything" or "I'm not learning anything from this"....which was so strange. Seems like it was in the same discussion where she was telling George she needed to be home when Caylee returns home iirc. At the time I did always think maybe she had mistakenly assumed that her parents had taken Caylee from her. And I always wondered why George didn't say something like, "What do you mean this isn't teaching you anything? I don't understand."

I believe KC was saying "Mom put me in jail for taking the car, the money. No one knows Caylee is dead. I can just ask mom to drop the charges and I will be out of here and on my merry way." She blames it all on mom here.
I don't know if KC learned anything from jail other than how to be alone for more than a few seconds. It seems she may just have learned that lying will still get you off, making up wild stories are believed by the fools if you just fake it long enough. I don't think she learned anything that jail is supposed to be about, but most criminals don't. KC's case is worse b/c lying actually worked for her legally, not just with her family and acquaintances.
