We actually did give some thought to that because we know there are people who will present with problems after the six-month screening has been done. We did give some thought to whether there was a need to systematically go back across and re-screen. It is an enormous effort to do that screening. I would never say that the effort would not be worthwhile because that's a harsh kind of thing to say.
But I want to give you some encouraging information. I had occasion to review all of the files from the Chicoutimi fire, for all of the sailors who were on board Chicoutimi. Over time, since that fire, a little over 50% of them have in fact been diagnosed with PTSD. They underwent the enhanced post-deployment screening, and probably only about half that number screened positive at the time. I think the effect of that mandatory screening made approaching people for mental health care a whole lot less scary, so that maybe six months after they were screened, when they realized that things weren't going very well and they were having flashbacks or nightmares, it was not threatening to walk into the clinic or to pick up a phone. I think that's a very powerful effect of the enhanced post-deployment screening, and I'm hoping that applies to the problems the army finds.
