Universities are either private property or government property, so they have a right to deny you carry privileges when you are on that property. While I believe guns should have no place in schools, schools are obviously not sequestered from society.
What would I do if this horrible crap went down while I was sitting in class?
???
Damn, I honestly don't know. I'd have to hope to be lucky. I carry a mechanical pencil with a metal tip (especially on airplanes), but the limitations of that are obvious. I have my keys on a short chain with a clip, attached to my belt and easily at hand, but that's not gonna reach much farther. I could throw a chair, a book, maybe even a laptop to try to distract, but that's only possible with lots of luck anyway. Getting the drop on the gunman somehow is the only possible way, without better armament.
Did anyone see the idiot who proposed bullet proof textbooks as a solution to school violence?
My heart goes out to every one that was affected by this horrible tragedy. I hope for their sake that clarity can be made of this situation. A shooting happened at my other school, but nothing like this. I guess I just don't know what else to say.
Peace be to them.
