The Met said it released footage of the arrest of the suspect in the Golders Green knife attacks in April “in response to a narrative growing online which criticised the force used by officers, who were bravely apprehending an armed man”.
It added: “It was put into use again following the significant public order policing operation last Saturday, where we were able to provide an insight into the abuse officers faced from protesters and the challenges involved in intervening in dense crowds to make arrests.”
London’s police force began an initial pilot of 500 body-worn cameras in May 2014, with a mass rollout to thousands of officers in October 2016.
Human rights advocacy group Liberty has warned that UK police forces already use earlier versions of facial recognition technology, which combine footage recorded on body-worn cameras with software to provide retrospective facial recognition searches.
