It's interesting, because if you look at the recent review that was done of veterans and post-traumatic stress disorder, there have been a number of quite serious cases. The professor from the University of Manitoba who did the review was very explicit about the importance of addressing the firearms issue, because, of course, people in the military are more likely to have access to firearms.
Mental health issues are always difficult to assess, treat, and judge the severity of. I think, again, no one is saying necessarily that, because someone was depressed 15 years ago, they shouldn't have access to firearms, but I agree with you completely. Suicide prevention experts will say that most suicides are preventable. Even though public opinion is often that if someone wants to kill himself, he'll kill himself, it's not borne out by the facts.
When I started working on this issue, I think about 1,100 Canadians killed themselves each year with firearms, and even though the population has increased, with progressive strengthening of gun laws, we've seen that halved. There has been a very clear decline, and the research shows that, as you put more emphasis on screening and controls over firearms to keep them away from people with mental health issues and build that into your screening, you can reduce suicide.
One of the recommendations I didn't get to bring forward came from the Canadian Association of Emergency Physicians. They proposed that physicians be required to report people they think ought not to have firearms, in exactly the same way most provinces require them to report people who ought not to drive motor vehicles. That would go a long way to addressing this more systematically.
