Do AI detectors work? Students face false cheating accusations

Do you think it stupid to scan kids for weapons, or stupid to think that a metal detector will find weapons?

Not the OP, but obviously it wasn't a metal detector, otherwise it would've detected all brands of laptops as weapons. It's probably an image based detector.

The problem is, if it has been that badly tested that it detects Lenovo laptops as weapons, there is a good chance that it doesn't properly detect actual weapons either.

I think it's overboard to scan for weapons at all school but very important to scan at some schools.

I think it's stupid to have a country where guns are legal.

Guns are legal in almost every country - I think your problem is with countries that have almost no restriction on gun ownership. e.g. Here in the UK you can legally own a properly licensed rifle or shotgun and even a handgun in some places outside of Great Britain (e.g. Northern Ireland).

Just because something is technically legal, doesn't mean it's in any way common or part of UK culture to own a gun.

There hasn't been a school shooting in the UK for nearly 30 years. Handguns were banned after the last school shooting and there hasn't been one since.

Although that fact is sometimes forgotten by schools who copy the US in having "active shooter drills" though. Modern schools sound utterly miserable.

A high school I worked at had a similar system in place called Evolv. It’s not a metal detector, but it did successfully catch a student with a loaded gun in his backpack. Granted, he didn’t mean to bring the gun to school. I think it’s stupid to believe that kids who want to bring a gun to school will arrive on time to school. They often arrive late when security procedures like bag scanning are not in place.

let us ban knives then...

got a license for that mate?

Exactly. It's not the legality of weapons, but the easy availability of them that causes the issues.

It seems to me like victim blaming for U.S. schools to have active shooter drills - it makes more sense to have much better training and screening of gun owners than trying to train the victims. However, given that the NRA is excessively powerful in U.S. politics, I can see why they are necessary, but it just seems easier to me to stop kids from being able to get hold of guns (e.g. have some rudimentary screening for gun purchases and require owners to keep them in locked cabinets when they are not in use).

This is a tired stereotype.

The US has more stabbings per-capita than the UK does, even on top of the shootings.

There's already a UK ban on carrying knives in public unless you have an occupational need and they're wrapped up or at least not just sitting in your pocket.

Licensing wouldn't be worthwhile as almost every household would want knives for food preparation.

It's stupid to bring yourself into a position where scanning kids for weapons is necessary. In this case we're already past that, so the stupidity is that the device isn't updated to not identify laptops as weapons. If that's not possible, then device is a mislabeled laptop detector.

Yet the murder rate was unaffected by the gun ban.

Why do people say such unsubstantiated nonsense. Places with guns have more death. And it's obvious to see why guns are a tool for for killing, and they're pretty effective.

Yet the USA's intentional murder rate per 100k population is 6.383 while the UK's is 1.148 [1]

If the US were a functional democracy, and continued letting unrestricted gun ownership be legal, you could argue that the US citizenry is being stupid. But the US is not a functional democracy, and meaningfully reforming anything is impossible, regardless of whether most people want it or whether it’s a good idea.
