What I will tell you is what I tell city councillors in Calgary. Separately, I am their ethics adviser. I take it from the idea of defamation, which is that you can have whatever opinion you want and you can express that freely; just say the factual basis of it so that anyone hearing it can be in a position to agree or disagree with you.
I mean, that's an ethical question, isn't it? We're asking any elected official to be faithful to facts, to set those out clearly and then express that opinion. I think that's the way forward. There's no oversight mechanism for it, but that's what the goal should be.
