Violence interrupters

People trained to discourage locals from taking a stand against weak invaders that never tell anyone in the city they invaded what they did to their city but still think they own the place, and to instead fall in line with their bullshit agenda/plan via violence to combat violence until the police show up to detain these locals.

Violence interrupters know they're there to provoke things further rather than to reduce anything, which is why they're not the funny kind of joke.
