NYPD Blue S07E03 - The Man with Two Right Shoes

Russell, Kirkendall and Martinez sense that a young boy is being exploited by his adult teacher. Meanwhile, Sipowicz, Sorenson and Medavoy investigate the vicious murder and castration of an out-of-towner who hired male prostitutes on his frequent trips to New York City, while Andy and PAA John Irvin find an effective way to deal with some firefighters who might have taken more than evidence from the crime scene.
