Unlike comparable bodies like the U.S. Federal Bureau of Investigation, the NPA does not have any police officers of its own. Instead, its role is to determine general standards and policies, although in national emergencies or large-scale disasters the agency is authorized to take command of prefectural police forces. Policy for the NPA in turn is set by the National Public Safety Commission.
