. Suppose there is a referendum in France, calling for thieves, robbers, murderers and rapists to be rounded up and put into camps surrounded by barbed wire and armed guards. The referendum is passed by the electorate, in a democratic election.

The camps are constructed and staffed, and convoys of soldiers collect thieves, robbers, murderers and rapists and move them into the camps. They might rely on local people to identify the thieves, robbers, murderers and rapists in case they are difficult to recognise. Work colleagues would be encouraged to name thieves, robbers, murderers and rapists, or even descendents of thieves, robbers, murderers and rapists (depending on the precise wording of the referendum and any laws which arose afterwards). Schoolchildren would be encouraged to identify thieves, robbers, murderers and rapists families. Loyal citizens of France would do their utmost to "cleanse" society of the thieves, robbers, murderers and rapists. If they don't help, then they can't be loyal, can they?
