I can imagine a Politician saying that the private business of a "private" company is nothing to do with them but what have Politicians done when their consituents were jailed for fraud? Did they assume it was true because they didn't know how many other people with no previous convictions were also jailed?

I guess it is hard since it happened over such a long time, it is easy to assume that the levels look legit, a few 10s of people per year or whatever. Sounds really scary though.
