My Lords, I do not know the details on that specific point so perhaps I may come back to the noble Baroness on it. However, what I do know, because we do have statistics, is that cameras have made a considerable difference in car parks in terms of attacks on cars or attacks on people within those car parks. I have no doubt that CCTV adds value. We also have a lot of hearsay evidence, which is why the regulator must go into it, of rather unpleasant people and yobs saying, "Look out, there's a camera". I do believe that it has an impact, but we need definitive and accurate analysis of it.
