The Dean of Student Life was correct. Yes, I would call 911, but it would be after the intruder was either deceased or completely incapacitated. No, I would never confront the intruder. My Remington 870 12-gauge pump would do it for me. If the student lived on campus, he could face disciplinary action (including dismissal) for possession of a weapon (the sword) on university property. If he lived off-campus, it is none of the university's damned business what he keeps in his home for self-defense.
