KETTLING - what is it and your rights
by @1312foryou

"A kettle is when police surround demonstrators to keep them in a particular place. Kettles can be very large, holding hundreds, or very small, containing only a dozen. The key feature of a kettle is that people are held within it until the police decide to let them go. In a number of recent incidents, police have decided against releasing protesters, and instead have carried out a mass arrest.

[...]

-Protests that move quickly along unplanned routes are more difficult to kettle.

-Police also feign kettles - make it look as though they are about to kettle - to disperse a protest or make protesters move away from a certain area.

-Sometimes it is possible to see a kettle being formed and to move away quickly before the kettle closes, but it is often hard to see it coming. Processions which move quickly are more difficult to kettle, but may be easier to split up or disperse."
