Proof that common sense has been around a long time, even if it does seem to be going extinct:
"...quemadmodum gladius neminem occidit, occidentis telum est." [...a sword never kills anybody; it's a tool in the killer's hand.] -- (Lucius Annaeus) Seneca "the Younger" (ca. 4 BC-65 AD
Or in another words... "Guns don't kill people, People kill people!" -Unknown
