The Dinosaur

Officer Art McCall returns from eight years on disability and rides with Malloy and Reed to see how much has changed in law enforcement. McCall soon learns exactly how much has changed when he tries illegal techniques to help a young woman with her ex-con husband, fails to Mirandize a boy after arresting him for robbery, and screws up an arrest of a gun-carrying man who later plants a bomb in his ex-wife's car, which requires Malloy to dress down the veteran officer on his use of antiquated (and illegal) police procedures.
