I understand the impulse to call the cops on your teenage kid. It's an urge a father should resist, and I predict a bad outcome for a family down in Everly.
The head of the household was rooting around in his 17-year-old's bedroom. He found a little pot and some drug paraphernalia, so he called the sheriff and invited Officer Friendly to search the rest of the house. More contraband was discovered, and Pops waved bye-bye to Junior as the forces of law and order hauled him off to the clink.
Family values, eh?
Better alternatives suggest themselves. You might have been able to talk to the kid. If not, a boxing lesson was in order, from you if you're fit enough or otherwise from a well-muscled uncle, maybe. Choosing to invite the po-po to handle your family dysfunction leads to problems you weren't smart enough to think of. Among them:
1. Sooner or later the cops are going to send him back, and Father's Day at your house is likely to be a restrained celebration.
2. You're probably stuck with him for longer than you planned. The arrest makes him a good deal less employable. Even the Army won't be anxious to take him off your hands.
3. If your motive was to teach the lad a good lesson, you undoubtedly did: "My Old Man is a Treacherous Bastard."
