I'm not an expert on intelligence about domestic radicalization, but I think anyone could observe that there's a higher incidence of such radicalization now than there was, for example, 30 or 40 years ago. This certainly is a challenge for many western countries.
The typical profile that's been developed by intelligence agencies with respect to the recruits targeted by terrorist organizations is that they were born in western society and are typically adolescent males who are looking for some kind of identity, who are perhaps going through very typical adolescent angst, and who are recruited initially by finding websites and material on the Internet that helps to give a comprehensive world view that leads them to a nihilistic extremism. Often after that they're connected through local discussion boards on the Internet. They eventually start finding people in what may constitute an informal cell—I think this pretty much typifies what happened with the Toronto 18—and then those people may start meeting and training and moving to action.
Our intelligence and police agencies are extremely vigilant. We should be very grateful, as Canadians. Sometimes we take this stuff for granted. Sometimes we don't think it's really serious. Sometimes the coverage of the Toronto 18 is that they were just a bunch of kids who were fooling around. That is ridiculous. The evidence is clear that they had the clear intention, a potential capability, of obtaining large-scale explosives to kill hundreds of Canadian civilians. We should not be naive about this threat that exists in our society or in other western societies.
