The case of R (Bridges) v Chief Constable of South Wales Police & Information Commissioner [2019] EWHC 2341 (Admin); [2020] 1 WLR 672 is said to have been the first claim brought before a court anywhere on planet earth concerning the use by police of automated facial recognition (“AFR”) technology. There could be nothing wrong with posting scores of police officers with eidetic memories to look out for up to a 800 wanted persons at public gatherings. So why not use a powerful computer, capable of matching 50 faces a second with a database of (under) 800 suspects, to do this job much more cheaply and instantaneously, flagging any matches to a human operator for final assessment? According to the Divisional Court in Bridges, this may, depending on the facts of each particular deployment, be lawful.
