How does a professor lose their tenure over a sex scandal which he was not involved in? The Michigan State University (MSU) has moved to fire the medical school dean for the actions of the child molester / doctor, Larry Nassar.  Why does that happen in academia?  I'm interested in knowing why the professors around a convicted child molester also have to lose their tenure and jobs.  Is this a typical procedure of American universities?

For comparison, a person working in industry who is guilty of sexual crimes usually seems to be solely responsible and only they are held accountable - not their entire department of managers.
The Dean of the medical school is not being fired because he was involved in sexual crimes.

He is being fired because he poorly handled the Title IX investigation. He utterly failed to ensure the safety of student and patient safety, and he bears responsibility for that.

To characterize him as being "not involved in" the scandal is not accurate - the scandal is not only Nassar's actions, but that they were allowed to go on as long as they were without being addressed.
