Thanks was about to cut down on the quote wall too
I don't carry a gun myself nor does anyone else for that matter up here, only the Cops carry visible guns and even the criminals don't bring them for anything but crimes. Just the usual concealed knife no one knows is there
That said if anyone wanted a weapon there's always something
Air-Soft Rifles
Kitchen Set Knife Set
Swords
Backpacks with a rice cooker
Molotov Cocktails
Crowbars
3D Laser Printed Gun
The list could go on a while

That said these weapons kill less efficiently than a gun so the most efficient route is usually the preferred one for crime and the most efficient weapon is usually the ones criminals prefer.
I also don't want armed border guards with guns protecting school children inside iron-cross bar windows
Too much like a prison  
And signifies everyone should live in fear not a real positive message
(Security Officers are fine though prevent hooliganism watch to make sure no one damages cars in the parking lot etc preventing minor infractions.)

That said if you live in the middle of nowhere a tranquilizer gun for wild bears might be handy or a gun for alligators if nearby
I hear they do make a mean gumbo
