Identity Cards Bill

Perhaps the noble Lord can help me. I live in Wales at the moment. If I am thinking of being a terrorist and decide that I am going to go and live in Scotland where I can carry on my activities rather better, I could fill in a form and say that I am going to live in the south-west, somewhere in Cornwall. There is no check on that. I do not have to hand in my identity card and get a new one because you are not going to ask to see me. There is absolutely no check. People can disappear without any come-back at all. All that happens is that a change is made on the register about where they are living in accordance with the form that is sent in. Is that satisfactory? Does that prevent terrorism?
