I'll just briefly add to that.
Yes, I completely agree with the statement about the privacy aspect. There's a global trend of countries tending to offer some privacy protection to just their own people. The U.S. is a really obvious example. There are some privacy protections that it offers to its people, and it offers virtually none to foreigners. This is particularly troubling when you think about intelligence-sharing arrangements. If Canada can spy on the British and on Americans, and the U.S. can spy on the British and on Canadians, and the U.K. can spy on Canadians and on Americans, and everybody's sharing information, then these sort of protections don't necessarily kick in. It kind of becomes a free-for-all.
There is one more thing I'll mention very briefly, because it's not my particular area of expertise. I referenced Roach and Forcese earlier in this meeting. I want to mention what they said about the problem of silent oversight, particularly when you have a large degree of inter-agency co-operation. If a particular oversight body is only looking at its agency and not potentially seeing the broader picture of what's going on, that can present a challenge.
