Privacy advocates in the UK are claiming victory as an appeals court ruled today that police use of facial recognition technology in that country has "fundamental deficiencies" and violates several laws.

South Wales Police began using automated facial recognition technology on a trial basis in 2017, deploying a system called AFR Locate overtly at several dozen major events such as soccer matches. Police matched the scans against watchlists of known individuals to identify persons who were wanted by the police, had open warrants against them, or were in some other way persons of interest.
