I think that internal investigations are acting as a substitute for actual criminal investigations.
By definition if the investigations weren't made public I can't know about them, but you can look at someone like Andy Rubin: https://en.wikipedia.org/wiki/Andy_Rubin#Sexual_harassment_a...
As far as I'm aware there was never any investigation from real police for him.

And how does this work? Are prosecutors really like "oh ok, we won't do any investigating of our own then"? If so, who's more to blame, the companies doing the internal investigations, or the prosecutors for falling for it? If the police show up to a residence to investigate a domestic violence report, and then one of spouses answers the door and says everything's fine, should we blame the spouse more or the police for not following up?
