My hon. Friend is absolutely right. The challenge is not just to collect the data. A constituent of mine with a large estate regularly finds that people have been fly-tipping on it. Once, while sorting through the rubbish, he found a receipt from a fast food drive-through that included a date and time stamp. He and the local police managed to find the vehicle registration number, but when they went to the Driver and Vehicle Licensing Agency they were told that it could not release the name because of data protection. There has to be a way of using the evidence that we can get, because we cannot rely solely on catching the villains in the act, which is extraordinarily difficult, particularly in rural areas. Installing cameras everywhere would be prohibitively expensive, impractical and completely unrealistic. There has to be a better way of dealing with the evidence trail. My hon. Friend makes a sound point.
