As for the argument to extradite the individual, there would need to be plausible evidence he can be linked to actual war crimes, and not just because he belonged to the SS. Like it or not, there are going to be many thousands of individuals in Canada that have a past for which they have not been held accountable, but for which some had no choice in which to be involved, or were unable to comprehend what they were involved with. How many Serbian, Bosnian, Rwandan, Chilean, Irish, etc. etc. individuals have immigrated to Canada and have remained under the radar and led valuable productive lives here? This isn't to say that something shouldn't be done when they are found, but I think that it needs to be linked to actual acts that can be proven they are responsible for.
