Did you know that a pilot scheme to set up a national database of mugshots is already being used in some parts of England? Yes, another database:

The police are developing the first national database of mugshots so that they can use face recognition technology to match CCTV images with details of offenders, MPs were told yesterday.

The system is being developed in a pilot scheme involving the Lancashire, West Yorkshire and Merseyside police which has generated a database of more than 750,000 facial images over the past 18 months.
