Civil Service
From Tardis Wiki, the free Doctor Who reference
The Civil Service worked alongside the police force in the United Kingdom.
Jack Harkness disliked Civil Servants, comparing them to aliens with grey skin, who wore grey clothes and thought grey thoughts.
They used to wear bowler hats, as if they were badges of office, until they went out of fashion in the 1950s. By the 21st century, Jack bet that they still wore them in secret, like an administrative version of the Ku Klux Klan. (PROSE: Slow Decay)
