insecurity checkpoints

Walk through metal detectors, x-ray machines scanning purses and packages and check-in baggage -- these are devices that we may see much more of in the future. We have them at airports and in public office buildings. What we rely upon for our security aren't the machines as much as the people using them. Those people need training and they need to treat people as more than just suspects. There have been many troubling stories printed in the media about abuses committed by the people running security checkpoints. Perhaps the most egregious account I've seen is one reported on the pages of LewRockwell.com (via bOING bOING). Though, this article troubled me a great deal, too.
