The argument that a gun is a tool is still valid, and true. Ever hear the saying "My rifle is a tool I am the weapon" That's because some of us were trained to destroy materiel and people using the items at hand, could be a rifle or handgun might be a shovel. Due to this fact I have unbridled white hot hate for this "Zero tolerance" thing. Everyone is different and will respond in a different manner, my kids always had access to firearms and even some explosives (We used them for clearing stumps etc.) No problems but each child needed to be taught a bit differently. Now that being said what gives government the "Right" to demand how I treat items which I legally own (By right) in my own home. As a professional Peace Officer I would never enforce this edict on another, I may offer advice on the issue but ultimately it is up to the parents.
