I am very grateful for the lengthy explanation that the noble and learned Lord has provided. However, I still have questions. One of the examples he gave was to be able to interfere with equipment of a group of people who are accessing a particular website. I guess that you would need to know the IP addresses of the devices that were accessing that website to interfere with them, and that would be within the terms of our amendment. I may have lost concentration, and apologise to the Minister if so, but I cannot remember him addressing targeted examination warrants, where presumably the security services—the only ones who would apply for such a warrant—would know the identity of the people. I am still not clear about the need for thematic targeted examination warrants.
The big question that I have around testing and training is: who are the poor innocent people targeted by the warrants used for testing and training purposes? How is it decided who should be targeted? Will the Minister say what that other information is that needs to be specified in the warrant?
I accept that the withdrawal of these powers would be a mistake but, as the Minister acknowledged to begin with, these are probing amendments. I am grateful for the explanations he has given so far. Perhaps he might write to me to deal with my further and more difficult questions, but at this stage I beg leave to withdraw the amendment.
