First of all, we have different fora and different sets of rules, so even if everybody did their work in a very competent manner, it is very possible that the results in one forum might be different from those in another forum. I think it would not serve the credibility vis-à-vis the public that I was talking about if on the one hand the independent decision-maker made a decision and a committee—which is, by definition, partisan and displays partisanship—came to a different decision. I don't think that would be a positive result for anyone involved, let alone the impact on the person who would be investigated twice.
