The Metropolitan Police has announced it will use live facial recognition cameras operationally for the first time on London streets. From a report: The cameras will be in use for five to six hours at a time, with bespoke lists of suspects wanted for serious and violent crimes drawn up each time. Police say the cameras identified 70% of suspects but an independent review found much lower accuracy. Privacy campaigners said it was a “serious threat to civil liberties.” Following earlier pilots in London and deployments by South Wales Police, the cameras are due to be put into action within a month. Police say they will warn local communities and consult with them in advance.
