I think we've all clearly agreed that, yes, national security is a critical concern and it's a human rights concern. What we're trying to underscore is that the policies taken by any government, including the Canadian government, to address national security--be it immigration, security certificates, or any other practice--need to accord with the international human rights system.
This is the system that governments themselves set up. In its very terms, the system already recognizes the particular ways in which national security issues do interact with human rights. It recognizes that there are certain human rights that can never be infringed in the name of national security, and some can be infringed in only the most limited circumstances, in times of extreme national emergency.
So a whole framework within the international human rights system already addresses this.
