Understood, but sometimes very esteemed witnesses who have a lot to contribute to the discussion are available on only a certain day. Rather than turn away that witness who could add quite a bit to this discussion, we decided.... The witnesses are kind of designed in that the first two witnesses are from CAF-DND, the second two witnesses are two people with esteemed legal backgrounds, and the last two witnesses are academic in nature. They were paired that way to make it as efficient as possible.
I don't disagree with the theme behind your comment, but we had an opportunity for people we otherwise wouldn't have been able to hear from. So I take that on advice.
