No idea. I only replied to the guy saying that "metal detectors stop weapons". Which is false.
The evidence is in US law. Because they would be undetectable, 3d printed guns are required to have some metal inserted into it to be legal (https://en.wikipedia.org/wiki/3D-printed_firearm#United_Stat...). I think a guy who can 3d print a gun and wants to bring it onto a plane could probably skip that step;)

Laws written by people utterly ignorant of the subject they're legislating is not evidence of anything.

Taken in a strict boolean sense, yes, but real-world policy is rarely boolean, and mostly about tradeoffs and how many nines of reliability you want to spend on.
Metal detectors will catch the vast, vast majority of guns ever produced, which is their whole point of existence.
