Live facial recognition is a proven, lawful crime-fighting tool that has led to more than 2,100 arrests in London, including over 100 sex offenders who would otherwise have remained free to harm children. Independent testing confirms the technology is accurate and consistent across demographic groups, with just 12 false alerts from over three million faces scanned and none resulting in an arrest. Around 80% of Londoners back the technolgy's use, and the court has confirmed the safeguards are robust.
A court's backing of the Met's facial recognition program doesn't make mass surveillance acceptable — 4.2 million faces scanned in London last year alone is an unprecedented level of monitoring that no other Western democracy has matched. The technology already wrongly flagged an innocent man, who was detained for over 20 minutes and threatened with arrest despite showing valid I.D. Rubber-stamping this kind of dragnet surveillance sets a dangerous precedent for civil liberties across Britain.
