Without attempting to give a legal opinion in international law, I would have thought that any Canadian legislation that authorized torture would be contrary to the United Nations covenant and therefore, in international law at least, illegal. It probably would be declared unlawful by our own courts as well, for the same reason.
Might I suggest that you add to your list of administrative responses the one we've set out for you here, which is an independent audit of police forces, in other words, a proactive audit, not merely receiving information and considering it--a body that does the kind of audit that SIRC does for CSIS right now. It's one of the best examples we have of that kind of auditing body, a body that can ask questions, that can visit, that can look at documents.
If, to whatever extent, there is a body like that available and in place, then the concealment of some kinds of information becomes more tolerable because you know there's an auditing process going on by people whose job it is to ensure that the legislation is being followed.
So if you'd add audit to your list, we'd be very happy.
