I think it would require a poll to determine whether the Canadian public would think it had been served. I've no doubt the Canadian courts meet the requirements of the Geneva convention. I'm certainly not going to debate you on that point. I think it would be inappropriate, as I said, given the way battlefield detainees are captured and the lack of evidence taken at that time, to then try to obtain a conviction based on the sort of evidence naturally obtained when one captures someone on a battlefield, as opposed to at a crime scene, with careful documentation and witness statements and evidence.
I don't disagree with your point that if he can be tried in Canada, I'm sure the Canadian public will be satisfied, but I don't think it alters the fact that the process he's currently undergoing is just as sufficient to meet international legal requirements. So if Canada is trying to make a determination based on whether he's receiving insufficient process or not, I don't think there's a difference there.
