Arming classrooms is a direct solution to only the most visible problem. This is like doing the 5 Whys (http://en.wikipedia.org/wiki/5_Whys), but stopping after the first one. Underlying causes will continue, requiring increasingly drastic counter measures at superficial levels.

Completely agree, Arming everyone with bigger and better weapons is not the solution. it is an arms race within the society.
