another school shooting in U.S. of A. :(

Guns help though. I for instance have never heard of a drive-by stabbing for instance.

The problem is indeed bigger than guns. The problem is a basic lack of self-control. Most people have trouble limiting the use of forks near their face.

How come the mythical NRA concealed-carry heat-packing hero never seems to be where the maniac with the assault rifle is?

This is entirely telling:

In the 18 years before the gun law reforms, there were 13 mass shootings in Australia, and none in the 10.5 years afterwards

Exactly.
In a bare hand confrontation the chances to get away alive is so much higher then when both the aggressor and the victim are allowed to have guns, mainly because the victim will be dead long before thinking about his/her own gun.
