As someone who worked with the University Safety Office (albeit a few decades ago), I disagree.I took it as they (should) have better things to do.
A number of the alarms that had gone off are because a young woman was being attacked and all she could do was pull the alarm, to alert any kind of authority. Granted this was long before cell phones. Further, it (was) University Policy that police respond to any emergency call. I would imagine it's the same thing nowadays.
I don't have an issue with the police showing up for these things.
