Despite popular misunderstanding, there never was any character named "Juliet Bravo" in the show. The name of the show is the inspector's radio call sign,
Thought it might have been Juliet Delta to match the first female inspector there - presumably her male predecessor must have been less than pleased with the same call sign. Still it was probably preferable to Foxtrot Oscar
We once had a young lad start work and he was really upset when we told him his call sign was going to be Queen.............under pressure I gave him Quebec.
