Yes, people have always been arming themselves. I'm wondering how, in your mind, the escalation works here, though. If every responsible gun/home owner were to go out and arm themselves with (let's just say) an AR-15, since that's the current pariah of weaponry, what would the response be from those that wish to do those people harm? I'm not a gun afficionado, so I don't honestly know. I'm curious as to why the average homeowner would ever need such a thing, or any gun for that matter, because I live in a place where it's mostly unheard of.
