My Lords, the noble Baroness has raised a very good point. Very often, the pictures are not of sufficient quality. The CCTV regulator has just come into post and will embark on a programme of work to obtain empirical evidence to achieve that. He will come to us with that programme of work in the next couple of months and then move forward to look into some of these areas. Some cameras are not controlled by the Government, but they do give a certain security. Last summer, I travelled quite a lot on the Tube. Announcements were being made that there were cameras on stations and in trains. I thought that I would do my own survey and so I asked people travelling on the Tube what they thought. After the shock of someone talking to them and looking as though they were about to be mugged, they generally agreed that the cameras made them feel more secure. The cameras have a real value.
