To the editor:

Re “T.S.A. Experiments With Behavior Screening” (business, Jan. 8): Imagine if, in the year 2000, I had told you that after writing the government a check or being interrogated by a government employee, you might be able to avoid walking barefoot through an airport checkpoint. You would have rightfully called me insane. Instead of heaping yet more programs and exceptions onto an already bloated agency, perhaps it is finally time to completely rethink our approach to aviation security.
