Hovewer, it might as well be the case that he had a brain tumor like http://en.wikipedia.org/wiki/Charles_Whitman that had a tumor that pressed against the amygdala and caused his aggressive behavior.

A panic button at the secured entry control point.
All exit doors to have electronic locks with proof of closure switches to make sure the latch isn’t taped open.
