It's funny when people think when you sign your character up to be a "police", they think you'll actually do "police" stuff often. You don't. It gets boring, monotonous, and you'll probably be hated by the community for the rest of forever. Also, everyone and their mothers would be in jail. There's a reason why we don't get handicuffs for this kind of stuff. :P
