Ray looks like a police officer. But he's a graffiti writer, with a trim goatee and graying at the temples, who wears a stolen orange New York City Transit vest when sneaking into subway tunnels. He has a stolen set of keys that he says unlock subway cars, and he boasts that he has left his graffiti tag name, PRIZ, on subway cars at least 2,000 times in the past 20 years.

At 40, he says he has no plans to quit.

But if Lt. Steve Mona and the 75 other police officers who make up New York City's new antigraffiti unit have their way, Ray and other self-described "graffiti writers" will have no choice but to stop.
