Agree with sandwolf. This kid has been a bad apple with papa lawyer protecting him. Papa can't help him this time...
Is his dad a successful ambulance chaser? It would be a special kind of 17up to manage (1) to be rich enough to constantly bail out his children so that they make terrible decisions while (2) not spoiling them enough that they view petty drug money (sounds like the stash he had on him was worth about $5k) as not enough money to kill people and/or go to jail over.
Even if he was moving that much product every week, you're talking about $250k per year and a 17ing paper trail where you buy the **** over the internet. I would hope if I managed to raise somebody completely amoral or immoral, they would at least be smart enough to look at the risk benefit on that and conclude it's a terrible deal.
