Sir John Whittingdale (Maldon) (Con)
I beg to move,
That this House has considered police use of live facial recognition technology.
It is a pleasure to serve under your chairmanship, Dame Siobhain. I am grateful for this opportunity to debate the police’s use of live facial recognition technology. I have to say that this debate is somewhat overdue.
Any fan of Hollywood movies would think that the use of facial recognition technology is widespread, as in “The Bourne Ultimatum” and “Spooks”, and that it is commonplace for MI5 and the CIA to tap into CCTV cameras across London. I do not believe that is correct— I hope it is not—but police forces are using facial recognition technology more and more. It was first used in 2017, and it is now commonly used by the Metropolitan police, South Wales police and now my own police force in Essex, which purchased two vans in August and use it regularly.
On 4 October, I accompanied police officers on a deployment in Chelmsford High Street, who were hugely helpful in explaining to me exactly how they use the technology and, importantly, what controls are in place. They told me that they had a watch list of 639 individuals who had been approved by the superintendent and were wanted for questioning in relation to offences such as violence against the person. They included people with outstanding warrants, suspects linked to county lines, suspected shoplifters in that particular part of the county, and those with a sexual harm prevention order.
In the course of the 30 minutes or so that I spent with those officers, they recorded 1,500 faces of people who passed by. The officers assured me that those images were matched against the watch list to see whether they registered a positive, and if they did not they were deleted in less than half a second. During the time I was there, there were approximately 10 positives, which led to a conversation: a police officer would go and have a polite exchange to find out why the person had registered positive, and they were checked against the Police National Computer or Athena. That morning, that led to two arrests.
The chief constable of Essex has written to me and colleagues to emphasise the effectiveness of the technology and its importance to that force. He told me that they had so far had 25 deployments across Essex, resulting in 26 arrests and 26 other positive disposals. He said:
“This cutting-edge technology has enabled us to keep the public safe, and can save time and effort of our front-line, allowing them to do other work to protect and support the community.”
Kim Johnson (Liverpool Riverside) (Lab)
I thank the right hon. Gentleman for securing this important debate. There are suggestions that this technology disproportionately misidentifies black people and people from other communities. Does he agree that the Government must give us more assurances and ensure that more black people are not criminalised? We know that black communities are over-policed and underserved.
Sir John Whittingdale
I certainly agree that more assurances need to be given. That is actually one of the purposes behind requesting this debate. The hon. Lady is right that concerns have been expressed—
