"Poliziesco" is used generally to indicate every detective fiction production where police forces (Italian or foreign) are the main protagonists.Instead the term "poliziottesco", a fusion of the words "poliziotto" ("policeman") and the same "-esco" desinence, has prevailed (over the more syntactically-correct "Poliziesco all'Italiana") to indicate 1970s-era Italian-produced "tough cop" and crime movies.
