I make a living out of calling people liars to their faces. A lot of times they fight me, they all go to jail.
I think the Judge and Jury make the final call on who is a liar. You just round 'em up for processing.
Once arrested, that's when the process starts, so everyone goes to jail. You can not un-arrest someone, and the system has to make money
Don't know about your neck of the woods, but there are plenty of "Peace Officers" that know the exact dimensions of a cement block (at least the face they can see), and I also suspect that their counting skills have improved as well.
All just people interacting in a system of Chaos.
