In an uncharacteristic burst of non-stupidity, the Department of Homeland Security wants to allow small blades back on airplanes. Naturally, this causes consternation among people who don't understand what security means:

"It's not about scissors, it's about bombs," Mr. Hawley testified. "Sorting through thousands of bags a day at two or three minutes apiece to sort out small scissors and tools does not help security. It hurts it."

Weighing the risk of small scissors and tools against that of bombs, he said, "If you do the analysis, it is not even close."

But the committee chairman, Senator Ted Stevens of Alaska, said he found that logic "difficult to follow." Mr. Stevens proposed instead that the security agency reduce the number of bags that passengers may carry on board to one from two, giving the screeners fewer items to handle.

You will note two problems with Stevens' response. One is that he finds fairly rudimentary logic—should airplane security spend limited resources on bombs or on scissors?—hard to follow. The second is a more subtle but very common mistake. For a resource to be secure, not only must unauthorized not be able to access it, but authorized people must be able to access it. If it's "secure" even from the person who's supposed to use it, it's not really secure. Denial of service is a security attack. Self-inflicted denial of service is probably the biggest security attack in the world: think about the times you've lost your keys or forgotten your passwords. Stevens' solution allows screeners to check for both scissors and bombs (one of those two checks is worthless), but prevents passengers from having two carryons. Carry-ons are part of the service; fewer carry-ons amounts to a denial of service. Thanks, Ted. Though I guess in his world we are all driving across his bridges rather than flying in planes.

The only other senator at the hearing, Daniel K. Inouye, Democrat of Hawaii, said; "I could understand if some man or woman would want to bring on a knitting needle. I've seen a lot of ladies knitting. But I've yet to see someone cut paper dolls on the plane."

Perhaps Inouye stays in a private curtained booth, and is unfamiliar with the Swiss Army knife and Leatherman. And he probably hasn't seen this.

In other, similarly themed news:

[San Jose] officials said Thursday they were shocked to learn that Emerald Hills Golfland, a three-acre theme park with two miniature golf courses, had been placed on a Homeland Security watch list.

"The moment we realized it was on the list, it was taken off," said San Jose police officer Rubens Dalaison, who handles "critical infrastructure assessment" for the department. "I myself took it off."

But the list remains secret, and even San Jose Congresswoman Zoe Lofgren, who is the ranking minority member of a House subcommittee on terrorism risk assessment, said she did not know whether it is still listed. —Associated Press
