I didn't address this particular aspect of in camera, notably the leaking of information, and particularly reports and information relating to the discussions on reports, so I don't have a lot of the background.
But I would certainly be able to say to you that the worry I have there is that as soon as you start.... On the one hand, I think better education of members may be needed, so that they have some idea that this is not a trivial matter, that it's not something they can treat in a cavalier fashion, because I think you're absolutely right. If I may, Marie-Andrée is famous for reminding me from time to time--many, many times--to never attribute to malice what you can explain by stupidity. And it may well be that that little adage might go far, and that in fact members are just treating things as cavalier because, well, after all, “Everybody knows this; it's an open secret, you know.” Maybe by doing a better job of educating members, that can help.
The other thing is that if you get to the point where you have a member who is known to have done this, perhaps the fertile imagination of the whip in a given party can be applied to sanctions. One would venture to say that maybe that person is not worthy of sitting on a committee for six months.
