The size of the police force has almost tripled since the 1982 Argentine invasion of the South Atlantic British colony and its subsequent recovery by British forces. The pre-war, seven-man force now consists of a superintendent, an inspector, a station sergeant, a detective sergeant, and 16 constables. Basic or probationer training is carried out locally and is based on the British Home Office syllabus. There are no specialist squads on the force and only one detective. Officers are not armed as a matter of routine, but do have an armed capability. The force has its own fingerprint and forensic bureau, excellent photographic facilities, and a computer system which can provide the majority of services offered by the British Police National Computer. In 1988, the force investigated 330 cases involving 380 separate offenses and solved 64.6 percent of them.
