Consider: "and nothing being done against it" :-)

You interpreted it pretty differently from what I mean: Investigation-less corruption is often unofficially known/suspected, but can't be acted on. Investiation enables acting on it.

Of course the laws need to he tight on corruption in the first place. The kinds of corruption seen in the US are typically perfectly legal (we also have loopholes that should be closed, which makes me wonder why people often choose the illegal forms of corruption).
