So are typhoid and cholera — and civilized societies enforce reasonable laws to prevent them from disrupting life.
BTW, in case you're wondering: I'm a Texan who has owned multiple firearms for pretty much my entire adult life — I was taught to shoot at about age eight by my dad, with more-advanced instruction a decade or so later, courtesy of Uncle Sam.
And both typhoid and cholera have a nasty way of reappearing when natural disasters occur and sanitation takes a hit.
But hey, since we can't ever achieve 100% success for all time, then we should just throw up our hands and learn to live with 100% failure, right? Yeah, that's the ticket ....
