I think the degree to which a particular case is made public or not depends on the circumstances. When Dean and I and others advocate at times for more direct government involvement or more pressure being brought to bear by the department on a foreign state, it doesn't necessarily mean that it has to be done in public. In most instances, I don't think a public position, other than a general statement, would be required, but it doesn't mean that we take a soft approach to dealing with governments that, as Dean has described, quite often are fundamentally different from ours in terms of how they treat people.
In all the cases I've been involved with, the thing that I have experienced universally is the reluctance to offend a foreign government. You can offend a foreign government by making public statements that are unhelpful, but at times you have to offend a foreign government that's mistreating a Canadian citizen. That can be done privately, and that can be done effectively. I think that's what Dean and I and others are concerned about: the absolute reluctance to push the point beyond a certain diplomatic line in the sand.
