Facial Recognition: Police Use

Bobby Dean Excerpts

Wednesday 13th November 2024 Westminster Hall

[Bobby Dean (Carshalton and Wallington) (LD)]

Thank you, Dame Siobhain. I thank the right hon. Member for Maldon (Sir John Whittingdale) for securing this debate. It is shocking that this might be the first proper debate we have had in this place on this topic.

We have discussed whether live facial recognition technology is a legitimate tool and, if so, under what circumstances and controls it should be used. It is clear from the debate that there are many doubts, and we should probably be thinking about halting the use of the technology until we have cleared them up.

I will start with the concern about discrimination, which was articulated well by the hon. Member for Brent East (Dawn Butler). It is clear that black people and people from other communities are likely to be disproportionately misidentified by this technology.

[James McMurdock]

I want us to be careful that we are not making assumptions that may not be right. I am not taking a firm position, but there have been a number of comments, from several parts of the Chamber, about racial disparity. It would be remiss of me to let those things be said without making the point that I am not 100% sure that they are all accurate. For example—

[James McMurdock]

Of course. The topic of racial disparity is one we should all treat extremely seriously—possibly one of the most serious things we can do to benefit our society is to discuss this and get it right—but can we please not make any leading assumptions? We live in a fair and good society. If someone listened to this debate in isolation, they might get an impression that I do not believe would be strictly fair.

[Bobby Dean]

I thank the hon. Gentleman for his intervention, but the evidence is quite clear in this area. Somebody might watch this debate and have doubts, but the research is quite clear.

[Bell Ribeiro-Addy]

Further to the point made by the hon. Member for South Basildon and East Thurrock (James McMurdock), just about every time that somebody has stated that there are issues of racial discrimination with this technology, they have cited sources that people can look at. For the benefit of both the public and the hon. Member, it is important to note that these are not just assumptions; they are based on data and evidence. There is further evidence we could give, such as my personal experience and the experiences of others, but those specific points were made with evidence.

[Bobby Dean]

I agree with the hon. Member that some evidence has been cited in the Chamber today, but there is other evidence that we can look at. Let us not forget that the technology exacerbates the known problem—particularly with the Met police in London, where I live—that black communities feel over-policed and underserved. That has built up over time, and the use of this technology could exacerbate that problem further.

The hon. Member for Leicester South (Shockat Adam) made a comment about how polite conversations do not always register as polite conversations. That is because of the persistence of those conversations over time. A repeated polite conversation starts to become an aggressive conversation to the person on the receiving end, if it is that persistent. There was also discussion about the findings of the national physical laboratory, but it is clear that those findings are disputed—[Interruption.] Well, it is clear that they are disputed; they have been disputed in the Chamber today. Until we get to the bottom of that, we need to think carefully about the controls that we have in relation to discrimination.

I want to talk about the general principle of privacy. As a liberal, I feel a general depression about how we have come to devalue privacy in society, and how we trade it away far too readily for other societal aims. We often hear the claim, “If you’re not doing anything wrong then there’s nothing to worry about,” as if the only value of privacy were to hide things that someone might be doing wrong. That is not the case. Privacy delivers so much more than that. It delivers personal wellbeing and gives people control over their own data. It allows us to have freedom of association and dignity. We need to think very carefully before we so readily trade away the principle of privacy in pursuit of other goals in society.

The opportunity for slippage has been discussed at length. One would think that such technology would come with strict controls, but it is clear that at the moment we have the opposite; in fact, Big Brother Watch has described it as a “legal vacuum”. The hon. Member for Brighton Pavilion (Siân Berry) talked about the creeping expansion of its use in London. I have seen that myself; what started off being limited to large-scale events, such as football matches, has turned into routine trials on high streets, such as mine in Sutton.

We have also seen expansion in the photos that are used. The technology started off using only photographs of people known to the police, for good reason, but it has been expanded to potentially including everyone who has a passport or driving licence photo. What started being strictly about warrant breakers and sex offenders could expand to be about pretty much anything the Government of the day want. If we think about the clampdown on protest under the previous Government, that potentially has a chilling impact on the right to freedom of association.

With all of those doubts, it is clear that we need proper parliamentary consideration of the issue. The Lib Dems ask the Minister to immediately halt the roll-out of live facial recognition technology until we get it right. It should be down to this place to determine the correct controls and whether there is a legitimate use of the technology at all, given all the concerns about discrimination and privacy. Privacy is a fundamental civil liberty. We have undervalued it far too much in recent times. This is an opportunity to protect it, and we should take it.
