The fashion police are a force in equestria that arrests people for unstylishness, for example they arrest people who make unstylish jelly. They carry fabulous batons. Applejack believes that she and Apple Bloom can take them on.
Robot police are in charge of the capture and destruction of robots. They do not seem to be very good at it, considering Sweetie Belle has not been destroyed despite being clearly a robot.
Babs Seed owns the thought police.
