So now Schiphol is buying 60 scanners at >$15mil each. A billion dollars
can be spend a lot more effectively: decent wages so you don't have to
hire probationers, training, more personnel so they don't have to stay
at peak alert for 8 hours and overtime in one stretch, and lots of
social workers to have a good chat with every passenger before boarding
- if you're not showing any sign of preparing to strangle him you're
obviously not mentally fit to fly.

OTOH, it's possible to go too far with airport security testing:

The relatively low effectiveness has been documented, e.g.:

This is in spite of the TSA taking action against anyone reporting the
results of effectiveness tests:

Also, there are cases of testing being rigged:

This is just what I can immediately find via Google. I've seen many
similar reports, but I don't make a habit of archiving every news story I
read for the sake of future usenet discussions.

Beyond that, I wouldn't expect manual examination of X-ray (and similar)
images to be particularly effective. Monotonous tasks have a habit of
making the person performing them somewhat less than alert.

What would you do if you came home and found a pound of Semtec in your suitcase?
Some people would not tell anyone, and keep it 'just in case'.
