Occasional uses of 'Bloody'
'Crap' and 'Ass' are said a small number of times.
Overall, less profanity than in 'The Sweeney' series.
Infrequent uses of "For God's sake"
'Bastard' is used sometimes, and 'Shit' rarely. A few uses of words 'Hell' 'Damn' 'Jesus' 'God' etc.
One episode (Klansmen) features extensive use of racial terms like 'spade' and features a racist organisation, but is part of the plot rather than a general attitude.
Some politically incorrect jokes throughout the series which today could be seen as sexist or mildly racist.
