In police dramas, there was a move towards increasing realism. "Dixon of Dock Green" continued until 1976, but it was essentially a nostalgic look back to an earlier time when police officers were depicted as a mix of strict but fair law enforcer, and kindly social worker. On the other hand, detective series such as "Softly, Softly" (a spin-off from the earlier "Z-Cars") began to show police work done by fallible human beings with their own personal failings and weaknesses, constantly frustrated by the constraints under which they worked. Such series showed crime at the level of petty larceny and fraud, being tackled by ordinary coppers on the beat. Serious organised crime, on the other hand, was the province of various elite units, and one show in the 1970s set a new standard. "The Sweeney" presented a hard, gritty picture of an armed police unit — members of Scotland Yard's elite Flying Squad. Violence was routine, as were fast car chases; Regan and Carter were hard-hitting coppers, who when they weren't catching villains were likely to be on a drunken binge or womanizing.#2323123
