Live Facial Recognition: Police Guidance

Lord Hogan-Howe Excerpts

Monday 4th April 2022 Lords Chamber

[Baroness Williams of Trafford (Con)]

I disagree with my noble friend, because it is not left to guidance. Where guidance comes in is in the deployment. There is a legal basis on which to deploy, using powers including common-law powers. It was on the back of the court judgment that it was recommended that its use be clarified: the when and where of the use of LFR.

[Lord Hogan-Howe (CB)]

My Lords, I generally support the extension of facial recognition technology, although I take the point made by the noble Lord, Lord Clement-Jones, that it needs serious consideration. Technology is moving forward so fast that I think it is hard for all of us keep track of it. The three principles that the Minister might agree should underpin that are transparency of use, accountability about its use and that people should have a remedy. If things are done wrong, they should be able to check to see what they can do about it.

But the benefits are pretty outstanding. I know that, post the riots of 2011, we had to deploy 800 officers to look at 250,000 hours of rioters on CCTV footage. This allowed us to arrest 5,500 people over 18 months, but it took us 800 people. There has to be a smarter way of doing that. That would have been a retrospective use. Therefore, does the Minister agree that careful improvements in the future are wise, and that we should not stop, as the noble Lord, Lord Clement-Jones, suggested, the use of it altogether?

[Baroness Williams of Trafford (Con)]

I totally agree with the noble Lord. The legal framework in which it should operate is, A, for a policing purpose, B, where it is necessary and, C, where it is proportionate and fair. I think that pretty much accords with what the noble Lord said.
