But it's an unrequited love. The tech doesn't appear to have done anything for the Met during its past deployments. > Documents obtained by Big Brother Watch in 2018 showed the Met's deployments had rung up a 98% false positive rate in May of that year. Nothing improved as time went on. Subsequent documents showed a false positive rate of 100%. Every "match" was wrong. Not exactly the sort of thing you want to hear about tech capable of scanning 300 faces per second.
