Well, it's highly speculative, and, again, I'm not qualified to make an informed comment in this regard, but it's never slowed me down before, I suppose. Hypothetically, the Government of Canada could be engaged in sensitive negotiations with the Government of Afghanistan, or the government of some other country, with regard to the treatment of Canadians within their jurisdiction. It might well be that the position of the government at this particular time--and timing obviously is a consideration in all these matters--in trying to effect a favourable outcome to that situation could be adversely affected by disclosure of this document at that time.
Your question has been posed to me in terms of inviting me to speculate as to the reason the government might not disclose the report, so I'm in the position of defending the government's action here by what I'm saying, highly speculative as it is. One might well mount arguments of the kind you're implying to suggest why the documents should be disclosed, but you haven't asked me to go there, so I'm not going there.
