I completely understand what Ms. Damoff is saying.
My only concern is that witnesses we heard from couldn't reveal certain details because Marylène Levesque's case was still under investigation. It does no harm to broaden the study. Even if the two cases are different, we could seek out other information in an effort to understand things.
That's why I proposed we broaden the study to include other cases, even if they aren't all the same. This kind of thing happens all the time. There will never be two cases that are exactly alike. I think broadening the study would be well received.
