Jesus, you guys are way too tough on a teenager arrested for "suspicion" of DUI by campus police at the school he just publicly announced he was transferring from. You mean to tell me you guys never drove a single time when you shouldn't have?
He's under 21, and Arizona has a zero tolerance policy. Consuming soy sauce could have done the trick...who knows. Let he who has not driven with even a trace of alcohol in their system cast the first stone.
