Expert rejects Met police claim that study backs bias-free live facial recognition use

Academic says sample size was too small to claim new sensitivity guidelines have removed racial, gender or age bias

The Met is planning its biggest and most high profile use of LFR yet this bank holiday weekend at Notting Hill carnival in west London.
