Sir, can I say -- I have no wish to sound sycophantic. I'm really pleased that the Inquiry is here and that it is being conducted in this way, but I'm very clear it's about two things: it's about history and about actuality. It's about what might have happened but isn't happening any more and what might still, in theory or in practice, happen. You're fully aware of the need to address both of those. The terms of reference were specifically written. I know, sir, that that left that open and I'm keen that things are not assumed to be historic when they might not have finished in August or October or November or December 2006, and may have continued, but I'm conscious of the sensitivities about where and when that's dealt with in the Inquiry.
