Derek Bentley case

Derek William Bentley was hanged for the murder of a police officer, committed in the course of a burglary attempt. The murder of the police officer was committed by a friend and accomplice of Bentley's, Christopher Craig, then aged 16. Bentley was convicted as a party to the murder, by English law principle of common criminal purpose "joint enterprise". The judge in court sentenced Bentley to death based on an interpretation of the phrase "Let him have it", describing Bentley as "mentally aiding the murder of Police Constable Sidney Miles". The Bentley case became a cause célèbre and led to a 45-year-long campaign to win Derek Bentley a posthumous pardon, which was granted partially in 1993, then completely in 1998.
