In which I quote Gothamist and the NYtimes

Gothamist responds to yesterdays NYtimes graffiti story. Also, "The Times reported that since the formation of the new unit, there's been a 20% increase in arrests, contributing to a 78% increase in graffiti-related crimes for 2004. Tools that the police will be using: A database to track graffiti crime patterns (especially targetting repeat and the top 100 offenders), infrared cameras, and a reward program that offers $500 to anyone who reports a graffiti incident that results in an arrest and conviction."
