Can I have a 30-second follow-up on this?
We need to be careful not to confound categories. Terrorists, radicals, and extremist travellers, as the government likes to call them, are not necessarily one and the same thing. They're sociologically distinct categories. The reason I say this is that in this discussion we shouldn't conflate the problem of mass radicalization with the problem of the very small group of individuals who engage in unlawful conduct or travel abroad. We have people who travel abroad who have not been radicalized and who have not necessarily bought into radical narratives. We know, based on my own survey work, that we have no lack of sympathy in this country with radical narratives, but very few people who actually act on that sympathy.
We can't use one policy tool to address two very distinct problems. We need to have different types of policy tools. This, for me, is a kinetic, tactical, precision-type of intervention for that very small community of people who are looking to engage in unlawful conduct by leaving the country to join an organization or engage in activity that we have deemed unlawful. It is not, in my view, going to do anything or much about the problem of mass radicalization. That's a different issue and we need different types of tool kits.
