My Lords, the noble and gallant Lord has asked a number of questions. I would refute some of the claims made about the percentage of crimes solved by CCTV, which are based on inputs by individual police officers and accumulated in a certain way. No judgment has been made of their accuracy and general statistics cannot be given. It is worth knowing, however, that from April 2007 to March 2008, CCTV was used in 86 out of 90 investigations of murder and helped to solve 65 of them. The camera footage captured crime taking place or was used to track movements of suspects. In a third of those cases, witnesses were able to identify the murderer from it. CCTV plays a huge role with regard to serious crime and is very valuable. I have mentioned previously in the House that the regulator needs to obtain accurate, empirical evidence, but I have no doubt that CCTV is extremely important in stopping serious crime and in detecting terrorist offences.
