Well, I think it's fair to say there's an assumption that there is a deterrence effect and certainly that's a possibility. You would have to look again at the rationale for how we look at things from a scientifically statistically valid basis. If you assume that an unannounced inspection might catch things that you wouldn't otherwise find, then you'd have to assume that you're going to actually be able to be effective enough to see all of those things and that, by walking in and looking at things, you are going to see those kinds of things. I'm not sure there's any clear link on that, but we do agree that unannounced inspections are appropriate, and they are used where they are useful.
I will just distinguish that unannounced is very different from unplanned. We don't see a lot of use normally for unplanned inspections, because we should use our effective resources where they are best useful.
