The problem with revealing secret information, and there's always a desire for more transparency, is that doing that can reveal the collection methods. It can out your collection methods, whatever they were: human intelligence, signal intelligence, interceptions and so on. Revealing sources compromises them. Any journalist watching would understand the importance of off-the-record confidential sources and the risks of revealing sources, which means the information would dry up. If we want to be part of the club of Five Eyes, we have to present that we have secure systems in which information collected by our partners is not going to end up in the public domain.
What I would recommend to you is to go to Google, get the U.K. national security bill—which is before the U.K. Parliament right now—copy and paste, and bring it to Canada.
