I am not talking about the WORLD AS A DANGEROUS PLACE.
Crossing the road is dangerous - lets all buy a gun to shoot the motorists who might run us down.
etc etc.
Schools should be a place of safety. Not danger. If nobody had guns they couldnt go into an open school with trustingly open doors and shoot babies.
Schools have never been a safe place. in any event, how do you propose to remove all guns?
