I think it's going to be a difficult and expensive process, because for one thing, it's difficult to understand. Once somebody has been exposed to extreme levels of violence, once they have been highly radicalized and have been schooled in warfare, you'd hope that they would have just had enough, that they've seen it and know they've made a terrible mistake. I think probably the majority are exactly in that kind of mindset, but how do you know?
If my responsibility is to keep Canadians safe, if I'm responsible for our counterterrorism program, we would say, “Well, we have to run this to ground to make sure that.... Let's go out and speak to that person as frequently as we can to get a better sense of what's behind their motives and whether they've turned the corner or whatever.” The expensive part is that you still have to afford some level, I think, of coverage in the early portions of that process, but you can't cover everybody. The number of persons who are of concern greatly outstripped the capability of the security establishment back in 2012, and I hate to even think of what it is today.
