Are we ever really safe from each other, from an insider, from one of our own? Colleges exist to educate people, and they must be open to their own students. Protecting all members of the college community from one of their own who "snaps" and decides to terrorize from the inside is next to impossible. One could easily bring a dozen Glock 19 pistols onto a college campus undetected inside a flat-top guitar case. A number of shots could be fired before anyone familiar with a crisis response plan could respond.
