Lord Moynihan of Chelsea (Con)

Shifty is a great description—the noble Baroness could have said far worse than that. I was given a hard time and then let go. We have to accept that there will be errors, but we have to understand where this is going. We can less and less afford to have police on the streets—we have seen that problem—and technology has to take over. Look at the super-spotters, a very successful crime-fighting group in New York. They would go to an area where there was a lot of crime—noble Lords will know that there was a process in New York where they directed people to crime hotspots—where they looked at the gait of individuals to see whether they were carrying guns or knives. Soon, people in those areas discovered that they had better not carry guns because they would be stopped by these super-spotters and arrested. If you are not carrying a gun, which they had all stopped doing, you cannot kill somebody because you do not have a gun to kill them with. It was a tremendously successful operation in lowering crime. State-of-the-art facial recognition, at least before I stopped looking at it a couple of years ago, was more in gait than in face. We have to understand that you can start training technology to be much more effective than even these super-spotters at spotting people who are carrying, using their gait to recognise an individual rather than their face. There are all sorts of ways in which this software will be used to recognise people. It will get better and better, and fewer mistakes will be made; mistakes will always be made none the less, but that is the way of policing. They were mistaken when they stopped me—I was this tremendously law-abiding good chap, but they stopped me, and so will the facial recognition. I loved the description from the noble Lord, Lord Strasburger, of the 20 police hanging around, which I am sure resonated with noble Lords around the entire Chamber as the sort of thing that happens, but over time we will have to depend on technology such as this. We will have to be extremely careful about civil liberties, but we cannot blanket get rid of this technology, because it will be very important to policing.
