I'm not sure of the exact process, but I think countries come up on a rotating basis. Every four years or so, people feed into the human rights issues that they're concerned about, and it's taken to the UN. I think there are different levels to intervene on: the individual, the community, the policy, the politics, and international relations. In respect of the brutalities and situations of violence, Canada has an opportunity to feed into the country's record, and that is vetted in the appropriate place at the UN.
I think it does matter. It's a matter of collecting the information and ensuring that it's fed into the proper places, and that the people responsible are named and shamed. That can happen at multiple levels.
