I think it's a bit of a red herring to suggest that a lack of justice is at the heart of terrorism. Certainly if you take a look at the people involved with the 9/11 attacks, they were not people coming out of abject poverty. Certainly we're all in favour of justice and the promotion of human rights for all peoples, but I don't think this notion of root causes for terrorism can take away the fact that there are people out there with evil agendas. We need the powers to make sure, first of all, that they're put out of business altogether—because these are people who are associated with values that are completely antithetical to our way of life—but certainly to make sure that we here in Canada are protected from the ravages of these attacks.
