That's helpful.
I have a couple more specific questions, if I may, and I'll put them to whoever's wanting to answer.
With respect to international intelligence sharing, I'm assuming that in each of your four areas that's something you're invested in quite heavily; the security and intelligence establishment is heavily networked internationally. What constraints, if any, do you see with respect to this committee's ability to examine defects or even best practices in international intelligence sharing, because it involves other jurisdictions to which this committee would need access?
