I don't know how big the contingent of unvaccinated student is there, but if it is sizable, they all need to go enmass to the Chancellor's office, cut the wrist bands off, and stack them in a pile by the door. All while wearing a Nazi era Jewish ID'ed armband in tow.
Then see and milk the PR disaster if the university takes disciplinary action against them. That civil disobedience thing goes both ways.
