This disruption has been going on all week.
Here's how to deal with it.
1. Arrest every single bloody one.
2. Notify the Benefits Agency (or whatever it's called this week) of the names of all of them. They've been protesting all week, so clearly none of them have jobs. Protesting means they aren't looking for work, ergo no benefits.
Stopping these people's free money and sticking them in a cell is the quickest way to put a stop to all these shenanigans.
