@rnv That's a devastatingly accurate take. I just got the notice that there will be an active shooter drill in the library at the college where I teach. I was either off campus or at another obligatory meeting when the drill happened in the building where my office is, that houses the department I work in. It is truly sobering and more than a little frightening. There is no way to lock the entire campus down in the way that one can lock down a single school building. This is not to suggest that the situation on my campus is somehow worse, but it constantly gives me pause that we are an open campus and have no way of monitoring, much less controlling, who comes on campus, through which entrance, at any given moment.
