It’s a jobs program, that we all pay for three times over (in cash, in inconvenience, and for an unlucky minority, in harassment or worse). And because it’s a jobs program, it’s politically invincible.
Maybe we should just pay for fake red team terrorists too. Even more jobs, and keeps the agents in top readiness. Basically airport Counterstrike.
How is that possible?
The metal detectors and millimeter scanners are real at the very least, so I’d expect most weapons to be caught.
