Mr. Chairman, honourable members, I worked for a year and a half in Singapore. One of my colleagues there, Haniff Hassan, is regarded as one of the world's experts on deradicalization.
In the case of Singapore I think that passport revocation to them is a cut and dried issue, and they do it very quickly and very clearly. But I think it's worth pointing out that in Singapore it's done in the context of a much larger program. It's seen as one tool in the tool kit.
Singapore has a very effective deradicalization program, but as Dr. Leuprecht pointed out, it's successful because it's very narrow, very focused, and is very knowledgeable on life as it exists in Singapore. It's not just about moving the person away from the radicalized thinking, but also at looking at their families, their future, and how to integrate them back into the larger society.
So my short answer would be that passport revocation is good and a necessary tool, but I think it should exist as part of a larger larger effort, or tool kit as Dr. Leuprecht describes it.
