The four provinces of Pakistan (Punjab, Khyber Pakhtunkhwa, Sindh and Balochistan) each have their own police force, organised to suit the challenges of that locality, with their own specialised and elite units.

Most of the country's highest profile law enforcement positions are staffed by members of the PSP, including Inspector Generals of provinces, the Director Generals of the Intelligence Bureau and Federal Investigation Agency, and superintendents of the Frontier Constabulary & National Highways and Motorway Police.

Officers are recruited through an extremely competitive examination held once a year by the Federal Public Service Commission.

[19][20] The law enforcement agencies are also involved in providing first response to emergencies and other threats to public safety as well as protecting the infrastructure and maintaining order in the country.

Apart from investigating crime scenes, criminal acts, suspected unlawful activities, and detention of suspected criminals pending judicial action, the law enforcement agencies (primarily police) also perform duties that include the service and enforcement of warrants, writs, and other orders of the courts.
