Can a bad breakout lead to better behavior? Across the pond, Welsh police are hoping that it can. After witnessing a sharp rise in citations for antisocial behavior at a public housing estate, Cardiff officials are thinking of installing pink lights to deter teenagers who congregate, vandalize, and otherwise rabble-rouse. The lights make acne appear more obvious and intense, which is thought to send complexion-challenged adolescents running. The police, who raised the issue during a community policing meeting, can't make the decision — that's up to city officials — but the idea is gaining support in the beleaguered community. A skeptic could point out that delinquent teens may be inclined to destroy such lighting, but it's not as laughable of a plan as it seems: the success of a similar program in Nottinghamshire, England, suggests that an unflattering spotlight could be enough to fight crime.
