To understand our nation's frustrating war on drugs, consider a street corner on Avenue K just outside my district, a minor terminus for Brooklyn's illegal drug trade. As a New York State Assemblyman, I have often fielded constituent complaints about that corner and alerted the local police precinct captain. The police have usually responded with a sweep of the neighborhood, but the sweeps have rarely done any good. A day--sometimes hours--after police make their arrests, the drug traffic returns to normal. I know, because my constituents call to tell me "they let the dealers out again."
