If memory serves Farmington Hills is the place that hired an Orthodox joo as a police officer. He wears most of a uniform, but he has curly "sidelox" and a Yarmulke.
He was hired to soothe the nerves of the many resident Holocau$t "survivors" who panic at the sight of a man in a uniform and shiny black leather. Hence, the exemption to the uniform requirements.
