Something you must remember, is that a potentially violent act prevented by the presence of a gun, isn't going to generate much of a story, is it? That's because the gun has done its job, and no one can say what terrible things might have become, otherwise.
Nevermind that the media (certainly national media and its affiliates) wouldn't be inclined to publish/broadcast it in the first place, the fact is that the situation wasn't allowed to get out of control -- just as it should be when things work correctly -- and the absence of newsworthiness is in fact a sign of great success.
And none of this mentions a word about the peace afforded to good people everywhere, every single day, who know they are equipped to protect their loved ones from harm. That is priceless to them, rest assured.
Those are the facts about guns.
