A clintervention will never really work. Clint wants to be his kid's friends more than anything. This past year, it's been more obvious than ever. When they went out for pizza during the thanksgiving weekend, while his stepmom was telling him not to record, Clint was making dumb faces at the camera. After he was released from Jail and gave clint lip service about how he was going to cut back on the drinking, Clint let him drink at his grandparents house as long as it was only "one".
I'd hate to say this is how Clint potentially was when Josh was growing up, after all when Josh turned 18 and got his own place, he essentially washed his hands off of disciplining him which is fair enough. But I can see him, giving out vague rules or punishments to a teenage Josh, not following through with threats and letting him bend restrictions, and not providing an alternative structure.
