Other mistake: The registration number of the Ford Zephyr police car is RVP154G but the security etching on the window reads EKM414C.
Other mistake: In the episode where Sam has to defuse a car bomb, a small boy stares down the camera close up during the street clearance shot.
Factual error: In the penultimate episode of series 2, the date is given as July 1973, but in an earlier episode when the police were raiding the drug dealer's house, Cozy Powell's record "Dance with the Devil" can be heard. This was a Christmas time hit in 1973.
Continuity mistake: In the episode about the Asian drug dealers, when Sam is tied to a bed and an iron is roped to his chest, the ropes change position depending on the camera angle.
Character mistake: When Hunt was interviewing Rocket, he asked him who killed the "P*ki". At the time, the Asian man who had been shot was still alive in hospital, only to die later in that episode.
Factual error: Stopford House in Stockport is used for the exterior shots of the police station. It was constructed in 1975 and wouldn't have existed in 1973 when the show is set.
Factual error: Throughout the show in many street scenes and visible on some houses are satellite dishes. These were not available in 1973, only terrestrial TV through regular aerials. The first commercial satellite service In the UK was launched in 1989 by SKY.
Chosen answer: Sam is using the modern wording of the right-to-silence caution prescribed by legislation such as the Criminal Justice and Public Order Act 1994. In the 1970s, the wording would have been different, if it was used at all.
