If we move this situation to another environment, the difference in attitudes might be clearer. Let’s say a person like this is working for a firm, somewhere on lower steps of the ladder. He has a supervisor, and a manager, and a department lead above him. If several women took either of these three people aside and complained about rude behavior of the guy, he would be reprimanded and taken a note of (at the least) — if not for violating personal moral code of the administration then for fear of lawsuits. Further on, when the guy gets caught cheating on a work assignment that could result in monetary damages to the firm — that is even more serious. I’d say, at this point the guy will be out the door in no time. And if after the threatening letters start, criminal investigation will be started by ex-employers. Not “talks” behind the scenes, etc.

There is no direct connection between college administrators, their jobs/bank accounts, and an insane student who exhibits anti-social behavior. They don’t feel wounded in their wallets. Until it changes, modeling on business world, there will always be cases like the one discussed.
