When to Drop Charges

You have an obligation to your young participants (and their parents) to provide a safe and lawful environment. To do that, you may ban illegal drugs and alcohol at your events and expel those who flout your rules. But to best protect -- and assist -- those participants, you would do well to distinguish among the various transgressions you might encounter.

A 19-year-old drinking a beer or two at a party is unlikely to have a health problem. In many countries, he or she would not have even a legal problem. (Buy that beer in Detroit, you flirt with crime; cross the Ambassador Bridge and buy it in Windsor, Ontario, you're in the clear.) But a drug-addled 10-year-old very likely does have a health problem, one that requires not punishment but help, something best overseen by parents and not assistant principals (and certainly not the police).

UPDATE: The board voted not to report violations to a transgressor's school except as required by law.
