Use of technology at Notting Hill carnival could have ‘chilling effect’ on people’s rights, says equality regulator

Scotland Yard’s plan to widen the use of live facial recognition technology is unlawful because it is incompatible with European laws, the equalities regulator has claimed.

As the UK’s biggest force prepares to use instant face-matching cameras at this weekend’s Notting Hill carnival, the Equality and Human Rights Commission (EHRC) said its use was intrusive and could have a “chilling effect” on individuals’ rights.

The development will be a blow to Mark Rowley, the Metropolitan police commissioner, who has backed the use of the technology at mass events such as this weekend’s carnival, when 2 million people are expected to descend upon west London.

The EHRC has been given permission to intervene in a judicial review launched last month by the anti-knife campaigner Shaun Thompson. Thompson, a Black British man, was wrongly identified by live facial recognition (LFR) as a criminal, held by police, then faced demands from officers for his fingerprints.
