mormop writes to tell us the BBC is reporting that police in the UK have implemented a pilot program that allows officers to fingerprint drivers using a small handheld scanner connected to a database of approximately 6.5 million prints. From the article: "Officers promise prints will not be kept on file but concerns have been raised about civil liberties. [...] It is primarily aimed at motorists because banned or uninsured drivers often give false names, although pedestrians could also be asked to give prints if they are suspected to have committed an offence."
