"Scotland Yard's famous Vice Squad, which deals with prostitution and other aspects of London's underworld, has changed its title to the rather less dynamic "Serious Crime Directorate 9: Human Exploitation and Organised Crime Command", or SCD9 for short.
The explanation is one that would draw a robust response from DCI Hunt, the old-school detective from BBC One's Life on Mars and Ashes to Ashes.
Metropolitan Police sources said the switch had been ordered in part because the word "vice" was thought to have negative "connotations". It reflects a growing trend by law enforcement agencies to treat prostitutes as victims rather than as offenders.
Alan Moss, a police historian and former Met chief superintendent, said: "The jargon of modern policing, with all the numbers and letters, is confusing for the public and probably for people in the police as well. "I think the names of different squads should bear the name of what they do, and the crime they are trying to combat."
Detective Chief Superintendent Richard Martin, head of SCD9, said the name change was necessary was because Clubs and Vice had taken on wider responsibilities for areas such as human trafficking, which meant the old title was no longer appropriate.
