The phrase derives from the Riot Act, an Act of Parliament enacted in 1714. The legislation was designed to manage civil unrest by providing a formal mechanism for the dispersal of crowds. It required a magistrate or a similarly authorised official to read a specific statutory warning aloud to a gathering of twelve or more people, after which the crowd was granted one hour to depart peaceably.
The effectiveness of the Act relied upon the authorities’ subsequent immunity. Once the warning had been read and the hour had expired, the law permitted the use of any force necessary to clear the area. Those who remained were liable to face the consequences of the state’s intervention, a procedural threat that transitioned from a literal legal requirement into a metaphorical reprimand.
