When I read stories like this, I really begin to wonder if my country has gone irrevocably off the rails:

A few months earlier in the same airport, a tech engineer returning from a business trip to London objected when a federal agent asked him to type his password into his laptop computer. “This laptop doesn’t belong to me,” he remembers protesting. “It belongs to my company.” Eventually, he agreed to log on and stood by as the officer copied the Web sites he had visited, said the engineer, a U.S. citizen who spoke on the condition of anonymity for fear of calling attention to himself.

I guess that the Fourth Amendment is the latest member of the Bill of Rights to be put explicitly out-of-scope at airports.

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
