And this is exactly why criminals don't do this - use pencils or knives.

Criminals go out and get guns or make guns and then head for the school.

In a totally gun-free world, we wouldn't have guns to worry about. But now that guns have been invented, there will never be a gun-free world. There will only be those with guns, and those without them.

In addition, guns are an equalizer. A wimp might be able to stab someone with a knife. But a bully could stab someone over and over by holding him down and doing it. However, if the victim had a gun, the bully would be dead.

If both the bully and the victim had guns, there would be an equal chance that the bully would die. A gun is an equalizer. Instinctively, everyone knows this. Bullies go away when they see the victim has a gun. Bullies who are crazies will never go away, even in the face of a gun, except when they are shot.

So, having guns all around - open carry - is better for everyone, since guns aren't going away.
