Before I get into this week’s topic, can I interest you in a webinar on Fruit Knife Fighting?
Okay, thanks for indulging me.
For this week’s free article, I want to start by talking about a Facebook ad that… well, hell, watch it for yourself:
This is the first I’ve seen of this particular product. There’s absolutely no reason this… call it a single-use fire extinguisher, I guess… needs to be shaped like a gun. I suppose having a fire extinguisher shaped like a fire extinguisher wouldn’t be very exciting. I also wonder what you’re supposed to do if you fire this thing and it dumps its entire payload. I mean, theoretically, you reload and try again, like Hellboy trying and failing to take down a supernaturally powered monster…?
Make sure you don your fingerless tactical gloves for the operation, clearly. What caught my eye about this product (apart from the broken English in which it is presented, complete with AI narration) was the claim that it could double as a self-defense tool.
Spraying a fire extinguisher at someone could provide a momentary distraction, sure. it’s really just kind of annoying, though. It has no inherent capability to neutralize you in any way. If somebody is attacking you and you spray them with fire suppressant, you’re now fighting someone covered in fire suppressant. Maybe you make it slightly harder for them to see, but at the range you’d have to do it, I have to think you’d catch some of the payload, too.
Marketing this as a self-defense tool thus seems very reckless, especially given that they’re leaving the application up to your imagination. They mention the notion… and then just kind of let it drop.
This brings me to my point: Facebook and self-defense are very much a “buyer beware” sort of situation. The site reaches a huge audience that can be targeted by interests and other demographics, but there’s no guarantee that anyone who sees your ad possesses any specific knowledge. If you create in the general public the misconception that a fire-extinguisher gun can be used to blast an attacker, they’re going to expect some kind of results. The ad doesn’t describe what that might be.
This is for good reason, as again, it won’t do much of anything but annoy your target. If you want to experience what it feels like to get beaten up by a man covered in fire suppressant, by all means, spray him. This reminds me of the old joke: Do you know that if you hold a live badger up to your ear, you can hear what it sounds like to get attacked by a badger?
Use caution whenever a Facebook, Instagram, or TikTok ad purports to sell you something as being “good for self-defense” without once specifying why or how. Your imagination is much more powerful than any amount of ad copy. If they can plant the idea in your head and you, yourself, fill in the details, you will be that much more likely to buy.
Which brings me to…
Pssst! Hey, Buddy, Want to Be On A List?
While taking screen captures for this article, I noticed a different ad for Alibaba, the Chinese supplier. Clicking on it produced a broken link, which greatly annoys me… because I’d love to know how they describe this product:
That’s right: You’re looking at an incomplete frame for a revolver. If I had to guess, this is the revolver equivalent of one of those “80 percent lower” kits you could buy before the government clamped down on them. The schtick was that while it’s illegal to sell you a receiver without an FFL, an incomplete receiver is just a chunk of metal. If you were to go and drill some holes in it to make it a complete receiver, why, the manufacturer couldn’t possibly stop you.
(If this sounds familiar, it should: The old “switchblade kits” sold in magazines were just a switchblade with the spring removed. It was legal to sell the “kits” because the knives weren’t switchblades until the springs were installed.)
There’s a 100% chance that buying whatever that “steel casting” is will get you on a list, if not cause ATF agents to show up at your door. This is exactly like the stings the government ran when Wish was selling “oil filters” that were basically DIY firearms suppressors. More than one person who took delivery of illegal firearms accessories like that ended up with their door knocked down.
Facebook does a terrible job of screening out ads that violate their own draconian rules. They have rules against illegal weapons, against pornography, against indecent exposure, and so on… but every day, I see ads for things I really shouldn’t, including sexually explicit items. I’m no prude, but as someone who had more than one ad removed from Facebook because they used to pull anything even remotely related to self-defense, it annoys me to see the rules broken so flagrantly.
More importantly, though, a lot of people think that if something is advertised on Facebook to buy, it must be legal by definition. As with the fire extinguisher gun, just because they claim it works for self-defense doesn’t mean you should even try. When it comes to products like this “casting,” though, the danger is much greater. You don’t have to try and fail to use it in order for it to get you in big trouble.
People are interested in self-defense, which is why social media continues to serve ads for it. There’s a wide chasm separating interest and knowledge, though… and most of the Facebook and TikTok ads I’ve seen do nothing to close that gap. Keep this in mind… and make buying decisions very carefully. There’s always somebody watching and, even if there isn’t, there are almost always unintended consequences.
See you next week.
