Surely having a national database of fingerprints, DNA, etc kept securely under rigorous controls would prove beneficial in helping the police on a number of matters, e.g. theft, murder, rape, etc. The key would be to ensure that it is controlled properly. Remember that anybody convicted of a criminal offence has their fingerprints kept on file long after their sentence is over and nobody cries civil liberties about that. Surely this would be the same.
Not exactly the same is it? I would be totally against a national database of every citizen
