in the DHS/FBI memo, intelligence analysts provided airport screeners with a summation of “Potential Indicators of Shoe Tampering” (in case the following wasn’t obvious) to help them know what to be on the lookout for:
• Shoes with thick soles that could be hollowed out to allow the insertion of explosives.
• Wires or other unusual protrusions from shoes.
• Shoes that appear to have been dismantled and reassembled.
• Individuals walking in an unusual manner.
So the real question is, what happens to a person caught wearing this kind of modified shoe? In the recent European bus luggage scenario, the would-be shoe bomber wasn’t onboard. But the little known fact remains that suspicious persons wearing suspicious shoes are caught in U.S. airports more often that you think. But what’s disheartening — and worthy of an argument not with an airport screener but a policy maker or your Congressperson — is that in these cases, federal officials play catch and release.
