Homicide: Life on the Street Season 4 Episode 20 The Damage Done

A drug war is being fought--shipments hijacked, smalltime dealers shot, and even a family in their home are killed, leaving a small daughter hiding in a closet. Kellerman and Lewis catch the case(s) and learn a lot about the strange code of honor involved. The Narcotics detectives bring in a self-confessed killer with the murder weapon, but that's not the "whole truth."
