"There is good reason to believe that these scanners will increase the risk of cancer to children and other vulnerable populations," a group of scientists from the University of California at San Francisco informed the White House.
Aviation trade groups fear the public has finally been pushed over the edge. "We have received hundreds of e-mails and phone calls from travelers vowing to stop flying," Geoff Freeman, executive vice president of the U.S. Travel Association, told Reuters.
The new policy is being challenged in court by the Electronic Privacy Information Center, which says it violates the Fourth Amendment's ban on unreasonable searches. But don't expect judges to save us.
Says Stanford University law professor Robert Weisberg, with resignation in his voice, "Airports are pretty much a Fourth Amendment-free zone."
Though the harm to privacy is certain, the benefit to public safety is not. The federal Government Accountability Office has said it "remains unclear" if the scanners would have detected the explosives carried by the would-be Christmas Day bomber.
They would also be useless against a terrorist who inserts a bomb in his rectum -- like the al-Qaida operative who blew himself up last year in an attempt to kill a Saudi prince. Full-body scanning will sorely chafe many innocent travelers, while creating only a minor inconvenience to bloodthirsty fanatics.
_The good news is that last year, the House of Representatives voted to bar the use of whole-body scanners for routine screening. But only a sustained public outcry will force a change.
We will soon find out if there is a limit to the sacrifices of personal freedom that Americans will endure in the name of fighting terrorism. If we don't say no when they want to inspect and handle our private parts, when will we?
