The UK Criminal Justice and Public Order Act of 1994 vs. the riot act of 1716

(And I quote)

As an amendment to the Public Order Act of 1986, this part allows the police to apply to the local authority (or, in London, the Home Secretary) to prohibit 'trespassory assemblies' of 20+ people for up to 4 days with a 5-mile exclusion zone, as long as there is a risk of 'serious disruption to the local community', or of 'significant damage' to the land or buildings/ monuments on it which may have historical/ archaeological/ scientific importance. Anyone organising or inciting another to attend one of these may be arrested and imprisoned for up to three months. Attendance, and refusal to be directed away, is punished by arrest and a maximum fine of 1000.
