“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.
