“The only way you will ever eliminate this sort of thing is to make human beings forget how a gun is made.”
“Quemadmodum gladius neminem occidit, occidentis telum est.” (A sword is never a killer; it is a tool in the killer’s hands.)
Lucius Annaeus Seneca, circa 45 AD
Speaking of, a very made sword would be an effective at close quarters as a gun. Jim Bowie, though in a sickbed, was found dead surroiunded by several Mexican soldiers killed by his famous knife —really a short sword.
