I still don't see what's worthy of 15yrs in jail from what has been put out in the public. There are details missing from the story that would convince/push me to the side of it being a fair sentence, but they're not there. Fucking your daughters BF is messed up but if he's above the age of consent then where's the crime? She did not upload the sex tapes on the net (so it's not a federal crime), so I don't see where the crime is in that. "Involving her daughter in sex acts" is vague as hell, give me facts. She had a 3some w/her daughter? Where's the incest charges? Her daughter filmed them? She filmed her daughter and her BF? I just need facts. What was on the sex tapes, were the 16yr olds blacked out and then she got on top of them? She gave them alcohol, how much alcohol, are we talking a beer or 151 proof? It wouldn't surprise me if the judge was just personally disgusted by her behavior and threw the book at her.
I don't see what is damning about her admitting that. Most people stop their affairs when they get caught.
