As far as the practices not making us any safer ... I find it food-for-thought that no one has tried the bomb-in-the-shoe trick since we now all have to run our shoes through the scanner and go through the metal detectors shoeless....
If the scanning techniques didn't work at all, I'm fairly certain some other terrorist would have used the shoe scheme....
Even if Reid's shoes had been run through the x-ray in the way that is now required, it wouldn't have been detected. The only thing in the shoe itself was the heel made of plastique, and plastique is NOT detectable by x-rays. He did not have a detonator wired into the shoe -- he just tried to light the plastique directly with a lighter. (And FTR, most forms of plastique don't explode when you light it that way; it just burns.)
The reason that no one has used Reid's "shoe technique" isn't that the x-rays prevent it -- the reason that no one has used it is because it isn't an effective bombing technique, unless you can gather up a larger quantity of the explosive AND carry on the components for a detonator, AND get enough privacy on the flight where other passengers can't see you putting the whole thing together. (There is a reason why Reid was laughably unsuccessful.)
Now, if TSA created a explosives-residue-sniffing floormat that each person had to walk across coming out of the WTMD, *that* might do some real good. It would really slow down the line, though, because any time it alarmed you would have to switch it out for a clean one.
Also, think about this: most travelers have multiple prs. of shoes with them going through the scanner if they have a carryon bag. What makes the ones that you are wearing at the moment that much more threatening than the ones that you have packed in the bag? There would be absolutely NOTHING to stop you from walking into an airside restroom or even sitting down on an airside bench and switching to a different pair, one that has not gone through the scanner in a separate bin, and which might even be a pair of fake shoes sculpted out of pure C4, but no one from TSA would ever know, because they are looking only at the ones on your feet at the time you walk through.
