I think the point of the OP (or the man quoted in the article) is not that a concealed gun would have prevented this particular attack, but that the attack is indicative of an increase in brazen brutality, and that being armed is a an even better idea when violence surges.

Being armed is not a magic shield that prevents any harm, and it is immature to suggest that most who carry think so. Most adults realize that being armed, or alert, or trained improves your chances to survice a greater percentage of possible threats, but does not guarantee survivaility in all situations. Only the childish or argumentative person would try to paint an armed person as believing it is a talisman.
