The issue with the FACFOA, of course, is that it's not up to Canada to impose. It says under article 4, “If a foreign state, in writing, asserts to the Government of Canada that a person has misappropriated property,” then Canada can take steps. It has to come from the outside. Unless Russia is saying, please, get....which is not going to happen, so the FACFOA is not an issue.
In terms of the 10 categories, let's say Eritrea says it wants to get these guys and grab their assets, I think the reason why we have these 10 categories, this list, is so we're not going after the innocent janitor or teacher, we're going at the elite who have the capacity to make decisions. The problem with being so prescriptive in your list is, for example, it says that “military officers with a rank of general or above”, and, well, there's a reason we had Colonel Gadhafi. They know that and so they adopt the title that will often get them out of these sorts of things.
In the case of the FACFOA, unless Russia is requesting us to seize that gentleman's assets, then that is not one of the pieces of legislation we can use.
