I don't see that as a silver lining at all but an overreaction. I do see how turning universities into lock downed facilities is a step forward.
Sometimes bad things just happen to good people. By living our lives in a bunker type mentality, what sort of lives would we have?
I’m not suggesting a bunker-type mentality, but at least being a little more aware, and having campus security keeping a closer eye on things, and at least realize that the threat is there.
