TSA head John Pistole defends the utter waste of his agency by noting that it no longer asks people over the age of 75 to remove their shoes when going through screening. This is utter nonsense. If screening shoes is a necessary step to preventing terrorism, then a 75-year-old's shoes are no less of a risk to security than a 74-year-old's shoes. One thus correctly concludes that there is no reason for any passengers to be removing their shoes in the first place. (Similarly, there's no difference to the risk of an aircraft from a personal computer than from an iPad, but security theater has us going through the inconvenience of removing laptops from bags.)
The fact that the TSA will not permit Bruce Schneier to testify in front of Congress is further evidence that the TSA policy is not empirically defensible. Related from Popehat citing our earlier criticism.
