Well, duh, speaking out non-anonymously also has a witch hunt, it is just a very short one.
IMO the witch hunt is a feature.
If you are dealing with sociopaths of this degree, and institutional tolerance of them, you should have VERY ACTIVE plans to divorce yourself from the situation.
Witch hunts frequently only bring the malfeasance to light and accentuate the magnitude of the problem to the social network associated with the sociopath.
Sociopaths and sociopathic organizations function either on outright control and fear, or lies and misplaced trust. Paranoia is the weapon against both of those, and especially places extensive stress on the sociopath who is working mightily to maintain the web of lies.
