I take Mr. MacKinnon's comments, and I understand. There are a couple of things that maybe you can share with us, not right now but by email, about who you might think is overlapping or redundant.
My concern with not having the deputy ministers there, as we may have listed, is that we've seen repeatedly in the past that we get people who show up and their only answer is, “Well, that's really not me anyway; that's someone else within the department.” We've seen already a lot of passing the buck on issues. I'd hate to see a continuance of that.
We can certainly go back, those of us who have put deputy ministers on the witness lists, or perhaps if it came from the analysts, they could have another look to justify it, but I'd be very wary about having deputy ministers not show up in order to have other people who could not answer questions.
