Secret service

This article is about the form of government policing. For the television series, see The Secret Service.

Because of both the secrecy of secret services and the controversial nature of the issues involved there is some difficulty in separating the definitions of secret service, secret police, intelligence agency etc. For instance a country may establish a secret service which has some policing powers (such as surveillance) but not others. A secret police may also be said to be a secret service. The powers and duties of a government organisation may be partly secret and partly not. The organisation may be said to operate openly at home and secretly abroad, or vice versa.

The most prominent organization bearing this title is the United States Secret Service, which is a secret service, and not a secret police or intelligence agency. The CIA fulfills that role.
