Did anyone see the HBO program on the father that left his wife, started doing drugs(Pot and X), and began going to parties with his 18 year old son?  This guy let his 16 year old daughter and 12 year old son drink, smoke pot, and take X on camera.  The older son seemed to be more concerned with his younger siblings doing drugs than the father. The show was on fairly late so I didn't see the end of it but I image it ended with him going to court.

He ended up being a good role model, of what not to do. The kids all became drug free because they saw, and felt, what it did to him and their family. The father was left waiting to go to court on the drug charges.
