That's like asking why if we have a lock on the front door of our house do we also need an alarm system?

In my high school, there was literally a hole in the fence everyone used to climb through to ditch. As soon as it was repaired, another hole appeared. Hopefully kids aren't doing that nowadays, but yeah, it's hard to stop every possible entrance when so many kids are involved.

In other words metal detectors are just a meaningless gesture for show since they'd be easily bypassed.

No. Security (of all kinds) is about layering. Think of an airport. You have metal detectors which perhaps stop xx% of a bomb threat, and you have bomb-sniffing dogs which stop XX%, then security cameras, and you have the employees ask you if you packed your own bag, and then you have a response protocol to handle threats which provide added protection. Etc. It's about layers upon layers, with no one layer being entrusted to prevent 100% of anything.

Additionally, all these tools are deployed for more than just bombs. Guns, knives, explosive materials packed in suitcases, smuggled drugs, etc.

The same thing for schools on a more micro scale.

Oh wait is this an analogy to masking? And the point being that mask mandates don't work (in school setting at least)?

How many decades has it been since there was a bomb threat with an actual bomb in a school?

OP are you under 22 or something? Most reasonable adults don't ask stupid questions like this. (And yes, the teacher who told you there are no stupid questions was lying to make you feel better.)

I believe that windows can be opened...

Equipment can fail.

Bombs have non metallic parts that can be brought into school and dangerous.

There is a whole host of reasons.

People can 3D print pipe bomb materials out of alternate materials, like they do ghost guns. No metal needed.

OP here. The scanners can detect other non-metal contraband as well. They were able to detect when students brought cigarettes and confiscated them. They should be able to detect all types of bombs with 100% accuracy.

You cannot be that clueless, can you?

OP here. Then what's the purpose of scanning if it can't protect us from bombs?

In all likelihood, they can, but it's not foolproof and a bomb in the school is very very serious. If they have reason to believe there might be a bomb, they'd be negligent not to take it seriously and evacuate). There's a reason this is standard practice for schools and government buildings (the Colorado Capitol which also had metal detectors was evacuated because of a bomb threat yesterday).

I lived through many of these bomb threats as a kid (enough that I lost count), and managed just fine despite losing hours of instructional time.
