I'm not trying to evade your question, but I think it's a question that is more appropriate for CSE.
All I can say, though, is that this is a very broad mandate for CSE, and I think it's reasonable for commentators, legislators like you, to raise the point and ask questions. In essence, do we need that type of technique with regard to security? If so, how should it be limited? Should we have oversight with regard to those powers?
As I say, it's very broad.
