In this scenario, the university can not know if I am guilty or innocent. Therefore, it can not side with me and it can not side with the student. The only position for the university is not to protect me and let the legal system sort it out.
At no point did I say that the university should throw the instructor to the lions. I am saying that it should not protect the instructor because it is not its institutional responsibility. The university should leave it to the lawyers. There is no upside for the university, let's look at the two cases:
If the university sides with the instructor and the instructor is found guilty, it will be said that the university encourages sexual harassment.
If the university sides with the instructor and the instructor is found innocent, it will be said that the university covered it up.
