You know, I think the whole security checkpoint thing is fundamentally flawed.
Here's why. Humans are not capable of identifying devices that are actually dangerous. For example, something could be a laptop but actually be a bomb hidden in the laptop case. Or a camera. etc. Sure, metal detectors probably work on most of those, but not all. What about biological weapons?
And so it goes. The biggest purpose the security checkpoint serves is to provide a false sense of security.
That said, security guards CAN do something. But they won't stop a trained terrorist from taking over a plane. Isn't that the whole point of the TSA?
