re: #429 Rightwingconspirator

What is kettling?

It’s when the police split demos up into small or medium-size groups, and keep them in specific locations, usually without access to drinking water/lavatories.

If you ask to leave the “kettle”, you are allowed to, but you are then assumed to have left the demonstration/protest, so you’re not covered by the “right to assemble” or equivalent in the same way (in other words, the police can then require you to leave the area, and your rights decline pretty swiftly after that).
