You have surprising faith that the system is well designed.

Malicious actors don't get as stressed as normal people who don't want to miss their flight about the long series of obviously pointless tests. Why would they?

And there isn't anyone who surveils the queues and takes the worried looking for further checks. This can happen around immigration checks. It happens for flights to Israel. But not in routine airport security.

> going over a series of long tests will elicit unusual (fear, stress) responses from malicious actors

Oh, man. Let me tell you what kind of response going over a series of long tests by armed authority figures elicits on normal good-intended people...

This kind of thinking is as legitimate as believing lie detectors work, i.e., not at all.
