"In the criminal justice system, the people are represented by two separate yet equally important groups: the police who investigate crime and the district attorneys who prosecute the offenders. These are their stories." "Law & Order" is a blended police procedural and courtroom drama created by Dick Wolf. The structure for the one-hour show is a two-part approach: The first half focuses on NYPD homicide detectives investigating a crime - often derived from a real-life headline - and apprehending a suspect. The second half takes place in the courtroom, with the district attorney prosecuting the defendant.
