My hon. Friend brings a sobering note to the debate. Clearly, we need the powers and the standardisation of the quality of evidence to ensure that our constituents are protected, but Parliament, having put them on a statutory footing, needs to keep playing an active role to watch that the fears that he describes do not arise. I would say that about any power that we give to any colour of Government.
To stick to my practical points, I underpin what I was saying about the county lines raids and welcome the quality of evidence. The Bill will bring more power to the persecution of those evil people. I also pay tribute to my force, Dyfed-Powys police, and its trailblazing efforts in forensic science, which have seen cow DNA used for the first time in a conviction earlier this year. Any hon. Member who represents a rural agricultural community will know that forensic science is changing the way that we police our great countryside and shires.
A farmer in Dyfed-Powys lost a heifer in 2017. Like any good farmer, he soon recognised it in a neighbouring field but of course could not prove it, and the case went on with Dyfed-Powys police for some years. Luckily, a breakthrough in forensic science proved through DNA sampling that the lost heifer, which was next door with a naughty neighbouring farmer who happened by chance to find that obviously prize-winning heifer in his field and who produced a fake cow passport and, indeed, fake tagging, was his. He was reunited with his cow and there was a successful prosecution. I am pleased to tell the House that there was a £4,000 fine and £500 in costs. It was indeed a very moving occasion for all of us in Dyfed-Powys.
