This article builds on the "run, hide, fight" approach, but is interesting because it acknowledges that "people at the scene of an attack have a better chance of survival if they take an active stance rather than waiting to be rescued by the police," and (in the case of the Virgina Tech killer) "it was clear that the Virginia Tech assailant had 'one goal, and that seemed to be to kill as many pole as possible before ending his life.'"
Maybe some people really are starting to get a clue that you can't just pretend that there aren't bad people who do evil things, and then tell themselves that "it only happens elsewhere." That type of understanding could eventually lead people down the path of firearms being helpful tools and concealed carry as a useful deterrent (as well as effective means of protection in many cases). Who knows, maybe someday people will even acknowledge that just because you have a "no guns" sign you aren't any safer, and indeed are probably less safe. One can only hope.
