At the same time, John Pistole tells ABC's "Good Morning America" Wednesday he hopes angry passengers won't engage in a boycott of the full body scan, which he said would cause disruptions in long lines of passengers awaiting clearance for their flights.
Pistole says Transportation Security Administration screeners "just want to get you through" the safety checkpoints and are doing the jobs expected of them.
Asked about the Internet-driven boycott plan, he said, "There are some unknowns" as passengers arrive at airports. But Pistole also said, "That's one of the variables that we are prepared to deal with."
