My Lords, the only difference with what I seek is that if it is thought necessary to investigate someone—not necessarily to detain them—and establish their identity, it is sensible to have the power to take a sample that will help to do so. That is my point. Once again, I am not contradicting what the Minister says about the powers that already exist for the taking of samples from persons who have been detained. I am concerned that when, for whatever reason, it is regarded as desirable to establish someone’s identity, at the same time there should be the power to take the biometric samples required, which I am suggesting should be DNA because that is so much more certain and easy now than it ever used to be. I honestly do not quite see what the Minister’s argument is against that. Perhaps he could comment a little further on that before I withdraw the amendment.
