... or do you imply that the current random searches aren't working?</font>
svpii just gave one example of a random check that didn't work: switch carry-on with someone and your bag is on the plane. From my own experience I've been able to tell the screener that you don't need to open THAT zipper, it's just to expand the bag. I have a few other possible scenarios, but nobody has mentioned them, and I won't be the one who gives security new ideas.
