Police

Police
While the Marines maintain a high order of policing in the world, worldwide police officers are employed by the World Government to supervise local areas and arrest unlawful citizen.

Duties
The duty of a police officer is to maintain law and order, however they only deal with local interests unlike the Marines who maintain a global presence across the world. They leave the task of capturing tough criminals to the Marines, but aid them where needed. So far they have only deployed in small numbers which sharply contrasts the scale of deployment of the Marines.

Ranks
The police forces across the world seem to be independent of any ranks, mostly due to the fact Oda has yet to release any ranking system for them. However high ranking officers seem to wear a long coat, much like the HQ rank and above Marines.
