This is for movies where the protagonist(s) is/are members of any law enforcement agency, whether local, state, federal, or international. Movies where the protagonists are criminals can be found under crime films (though there may be overlap if the movie focuses half on each side of the law). The movies can be set in any country or time period, they can be dramas or comedies. The agencies may be police, FBI, ATF, DEA, NSA, Interpol, etc. It will not include intelligence agencies such as the CIA, MI5, etc., which would be found under spy flicks. It also will not include movies about private detectives, which would be found under mystery films. Nor will it feature entirely fictitious law enforcement agencies, nor real agencies appearing in science fiction.
