I am reminded of the guy with the CC permit and his CC pistol who tacked the nutjob in Tucson instead of using his weapon.
The psychological effect of having the weapon no doubt gave him some of the courage to do what he did.

No doubt in my mind. He plainly said that being armed gave him the courage to act.

He ran toward the sounds of the gunfire, not away. - The shy woman who wasn’t armed who grabbed the spare magazine from the shooter has to be highly commended. She refused the recognition of the press. (At least I don’t think she was armed.)
