Those impatiently awaiting the final series of The Wire might like to check out Law and Order. Over four episodes Law and Order tells the story of the British criminal justice system - a robbery, a police investigation, a trial and a prison sentence.
When it was first shown in 1978 it created a firestorm of political controversy. Furious questions were asked in parliament, newspaper editorials attacked every episode and the governor of the BBC was summoned to explain himself to the Labour home secretary.
