It's crazy that such devices are installed at schools at all. Also - metal detectors won't detect ceramic knives. So it's a security theatre anyway.

- machina_ex_deus 3y agoYou're not really defending against competent malicious adults which plan everything in advance. You're defending against angry teens who might decide on doing it because one day something pushed them over an emotional edge. In that case, just knowing there are security measures to overcome might be enough to make them never try in the first place. You're not defending against rational actor, you're defending against emotional actor and security theatre is effective against emotional actors.

I thought these scanners were installed (at least originally) mainly because of stuff like gang violence. I'd think a gang member (in their way) would be more like a "rational actor." Also you'd have to differentiate the "smuggling a weapon" from "stabbing." The weapon smuggling part might be rational, but the stabbing itself be emotional and irrational.
- zirgs 3y agoAn angry teen can grab a ceramic knife from the kitchen - no need to plan anything. You can also buy them at ordinary grocery stores. I have a few of them in my kitchen as well - they are really great.
- akiselev 3y agoIs there any evidence that’s actually true? Being emotional doesn’t immediately change someone into a brain dead moron especially when someone seethes for a long time before acting. Any would be attacker who knows the security even exists will necessarily plan around it from their first fantasy. Just feels like one of those solutions only we could come up with without actually solving anything. The teen TSA after school special version except with more dead kids.
- lxgr 3y agoIt’s not a matter of “being emotional”, but rather of emotional awareness and regulation, which people in general, and teenagers in particular, are sometimes not the best at. There are broadly two solutions (to that, not premeditated crimes): Help people to get better at that, and/or minimize situations where actions carried out in a moment can have terrible outcomes. Sometimes, one will be much more effective or feasible than the other; often a combination can work.
- brk 3y agoThat has been one of the points I have been making about these devices when discussed in security forums. "CIA Letter Openers" are easy to buy online, and would evade detection by any sort of metal detector, no matter if it claims to use AI or not.
- geraldhh 3y agoi heard that tapered toothbrushes make reliable self defense weapons
- brippalcharrid 3y agoOr offensive weapons; the classic prison toothbrush shiv can be a perfectly effective murder weapon, and its ergonomic handle can provide all the grip and support that an offender might need.
- zamnos 3y agoThat would be an argument in favor of the airport scanners instead of metal detectors, which I'm not sure is a good direction. I'm also not sure how many guns are ceramic.
- 0zemp2c 3y ago> I'm also not sure how many guns are ceramic. none
- geraldhh 3y agowrong. there is at least one. guns made entirely of plastic are also viable.
- 0zemp2c 3y agono there are no "ceramic guns" you can buy in the US, and unless you can tell me of one that is actually manufactured (including the barrel), they don't even exist and there is no fully plastic gun, even polymer striker-fired guns have metal components (notably, barrel, slide) please provide links
- mmcgaha 3y agoWhat does viable mean here? So no springs, a plastic firing pin and a plastic barrel? Then there is the metallic case required to make it do any work. I guess you could use black powder and a wooden match. Don't forget the plastic projectile.
- staringback 3y agoThat punk pulled a Glock 7 on me. You know what that is? It's a porcelain gun made in Germany. It doesn't show up on you airport X-ray machines, and it costs more than you make here in a month.
- _flux 3y agoI've read that commercial ceramic knives have metal embedded for that reason.
