I'll give you a concrete example of what you just spoke about.
In the Ben Johnson doping scandal—and there were others—they all knew each other. They all had a built-in relationship. They all knew each other. “Oh, no, that person wouldn't do that”, or they had a cone of silence. It was one or the other, but the inquiry brought it to light, removed that from being an acceptable standard and created the independent agency that was charged with monitoring and investigating doping.
So yes, a national inquiry would do that, because it would remove what you aptly described, which is the familiarity we all have with each other in sport that blinds us: “Oh, that is a good person. They would never do that.” Well, that's how predators work. They're good people, because that's their cloak.
