I notice signs around the schools that say "No Gun Zone". Well after what has happened at Newtown and other schools around the country I have the solution; just train the principal and selected teachers and arm them. Then place sign around the grounds perimeter "NO BAD-GUY ZONE". The cowards that they are will then take their mayhem elsewhere.
If one thinks about this problem long enough he will come to the same conclusion that I have. That is that an armed citizenry is a civil citizenry. The bad-a_ _ will think twice before jumping anyone for any purpose, hence a safer neighborhood. And while we are at it lets bring back dueling. That alone will make for a more civil discourse.
