So I searched for crime reports that matched its very dramatic description, the details of which guarantee it would make the news.
Not that this proves anything but it was supposedly on Tuesday and I found nothing even close to matching the tale of a home invasion robbery in which the occupant killed a lone armed intruder by means other than a gun (or with a gun for that matter).
Haven't even found any 2am armed home invasion robberies in a Google news search in the last week, without the dramatic ending either. Certainly not in a suburban setting.
Such heroic tales happen rarely enough and provide such propaganda value and appeal to base fears and ingrained narratives of how one would like to respond to threats that they are stock and trade of the NRA and pro-gun movement. They are told over and over (if they involve a gun used in self defense or the absence of a gun leading to an egregious outcome) and take a certain form with certain kinds of language and certain recurrent tropes (2am, safe neighborhood, a certain faux humility about the violence required to act heroically).
Not saying the story isn't true. Just saying hmmmm. Perhaps someone with better Google skills than mine can corroborate the episode with a link?
Very few people would be capable of the heroism described (of course the means of the lone villain's death is left to our imaginations) without military combat or police experience and training, with a gun or a knife or a baseball bat or fists for that matter. I've been robbed at gunpoint. I'm a big tough dude and I like as to shit my pants staring at that gun pointed at my chest. It was all I could do to comply as fast as I could. The adrenaline rush was unbelievable.
Anyone I know who could function effectively in such a situation as to kill an armed intruder manually already knows what guns they might need for what circumstances and likely owns them already.
