We (the non-lemmings of the world) already knew this, but:

he government's new order that all airline passengers put their shoes through X-ray machines won't help screeners find a liquid or gel that can be used as a bomb.
The machines are unable to detect explosives, according to a Homeland Security report on aviation screening recently obtained by The Associated Press.
In its April 2005 report, "Systems Engineering Study of Civil Aviation Security -- Phase I," the Homeland Security Department concluded that images on X-ray machines don't provide the information necessary to detect explosives.
Machines used at most airports to scan hand-held luggage, purses, briefcases and shoes have not been upgraded to detect explosives since the report was issued.
Of course, you will all be happy to hear:
The Homeland Security report recommends that explosives trace detection, or ETD, be used on the shoes and hands of passengers when the screeners determine they must be checked more thoroughly.
"To help close this gap, the percentage of shoes subjected to explosives inspection should be significantly increased," the report said.
In short, the shoe fetish as we know it is completely useless.
