What's the usual (North American) universities' practice on dealing with tenured professors who have been criminally charged? I've encountered two scenarios indirectly that could make some professors in some legal trouble.
Here the first scenario. When I was an undergraduate student, a colleague told me that his ex-girlfriend called because she discovered a stalker near her home. When he visited her to assess the situation, they bumped into the alleged stalker at the stairs of the apartment building. She asked him to call the police. He recognized that the alleged stalker was one of the professors in his department. He did not report the alleged stalker to the police because he's afraid of repercussion.
Fast forward a few years. Here the second scenario. One of my friends dated a tenured professor. The relation was abusive. He (the professor) hit her badly that she called the police. His mom begged my friend not to press charges because she's concerned about her son's future.
TL;DR: In theory or practice, would universities fire the professor who have been criminally charged? I've asked several tenured professors casually with at least one of the scenarios. They all agreed that nothing bad would happened to those professors even if their wrongdoings were reported to the police.
