There are a number of items there. You referred to some of them as more mechanical issues--the format of questioning, the rotation, and things like that. It's certainly true, I think; it's widely felt that it's not the most preferred system of getting at the heart of the issues the committee wants to discuss.
However, it's not just a mechanical issue. There certainly must be ways in which each party and each member can have a say, and I think committees have found that unfortunately it's probably the best they can do in terms of a format and there isn't necessarily a better mechanical way of solving it, because indeed, as we keep saying, this is a political committee. The members represent different perspectives, different ideologies, different parties, and unfortunately sometimes we have to have these mechanisms that are not ideal but are preferable.
The other issue you spoke about was whether things simply become more murky rather than more clear in questions, and particularly how issues like that may make inquiries more murky.
I suppose one person's murkiness is another person's actual attempt to clarify the issues, to bring in the full facts and the context. Again, that's often a matter of political disagreement: what is a problem to one side is a solution or a clarification or something like that to another side. I think it's up to this committee, in its own way, to try to work through that, to try to figure out how they can all agree on what is a problem, what is a solution, and what makes things clear. I think every time one member thinks things are becoming more murky, another might think they're simply trying to get the full facts and the full issues, even though it becomes more complicated, which is not the same as being more murky.
