I am not quite sure about the hon. Gentleman’s point because no one is suggesting that we would not want to access such information. My point is that, from a technical perspective, separating contact data from content data is much more difficult than the Home Secretary suggests. That means that we need more honesty about the powers we are proposing that our police and investigatory authorities should have.
For example, if someone can get information about my use of an electricity meter, they might want to look at the contact between me and that meter. If I were accessing it a lot, they might wonder what I was doing in my home that required so much heat. Drug enforcement agencies might look at such contact patterns, and inevitably that brings with it content about what someone is doing. That does not mean that we do not need methods to access that information; it means that one thing missing from this debate to date is an honesty about the technological complications that will come with this Bill, and we must address those concerns.
