I've wondered if Scott was always believed and stood up for when he was younger. The parents were in such denial (which is understandbale) but good grief. Parents have to let their kids experience the consequences for their wrongs when they are young or they'll always think they can lie their way out of things.
I have no idea if this is the situation with Scott as a child but like I said I sure do wonder... it could be a case of the kid who could do no wrong, finally did, but didn't get away with it this time.
