Old school version introduced by Newham Council in the late '90's

"Automatic face recognition systems in Newham-
Since 1998, Newham (pop. 235,000) has piloted face recognition software. Images are compared against a police watch-list, which is authorised by a senior police officer, of approximately 100 convicted offenders wanted for arrest or considered likely to re-offend. CCTV operators are privy only to the personal data that is necessary for this purpose. An operator verifies matches made by the software and for false alarms the CCTV image is deleted. The system is highly publicised to deter crime; youths placed on the list are taken to view the systems capabilities. Crime in CCTV areas has dropped by an average of 35%, but motor vehicle crime in the surrounding non-CCTV areas has risen by 10%. Crimes against property have risen and crimes against people have become less common. However, again it is not possible to identify how far these effects are directly attributable to CCTV use, as other crime reduction measures (e.g. community wardens) were introduced alongside."

They tried it just after the London Riots 3 years ago (not very successfully) and also had it for London 2012 Olympics. "To compliment the already famed CCTV infrastructure within London, new number plate and facial recognition software has been implemented."

Big brother is watching you. If you don't think it's out there you're a fool. If you think they just 'trial' it and then rip it out, you're also a fool. Especially since 9/11. It's for our own security don't you know. The ultimate justification for stealing liberty from a population.
