Stupid Band Names

Be careful what you write in your journal:

An airline passenger with the words “suicide bomber” written in his journal was arrested when his plane arrived in San Jose, California, on Wednesday, but the words appeared to refer to music and he was later released, officials said.

…”Preliminary, what we believe is that that was the name of either a band or a song,” Quy said.

I’m not sure I want “Suicide Bombers” displayed on my iPod. I certainly wouldn’t want to be in a band with that name, flying around the country with crates of gear marked “Suicide Bombers.” That would be asking for trouble.

On the other hand, it’s pretty sad what is enough to get you arrested these days:

“A male was observed by his fellow passengers as having a journal and handwritten on the journal were the words ‘suicide bomber,'” FBI spokeswoman LaRae Quy said.

“That, combined with the fact that he was clutching a backpack, and then finally he was acting a little suspiciously” prompted law enforcement to act.

My guess is that it wouldn’t matter how he held his backpack; once the jittery passenger saw the words everything else was interpreted suspiciously.

Turning Cell Phones off in Tunnels

In response to the London bombings, officials turned off cell phones in tunnels around New York City, in an attempt to thwart bombers who might use cell phones as remote triggering devices. (Phone service has been restored in two of the four tunnels. As far as I know, it is still not available in th other two.)

This is as idiotic as it gets. It’s a perfect example of what I call “movie plot security”: imagining a particular scenario rather than focusing on the broad threats. It’s completely useless if a terrorist uses something other than a cell phone: a kitchen timer, for example. Even worse, it harms security in the general case. Have people forgotten how cell phones saved lives on 9/11? Communications benefits the defenders far more than it benefits the attackers.

Security Risks of Airplane WiFi

I’ve already written about the stupidity of worrying about cell phones on airplanes. Now the Department of Homeland Security is worried about broadband Internet.

Federal law enforcement officials, fearful that terrorists will exploit emerging in-flight broadband services to remotely activate bombs or coordinate hijackings, are asking regulators for the power to begin eavesdropping on any passenger’s internet use within 10 minutes of obtaining court authorization.

In joint comments filed with the FCC last Tuesday, the Justice Department, the FBI and the Department of Homeland Security warned that a terrorist could use on-board internet access to communicate with confederates on other planes, on the ground or in different sections of the same plane—all from the comfort of an aisle seat.

“There is a short window of opportunity in which action can be taken to thwart a suicidal terrorist hijacking or remedy other crisis situations on board an aircraft, and law enforcement needs to maximize its ability to respond to these potentially lethal situations,” the filing reads.

Terrorists never use SSH, after all. (I suppose that’s the next thing the DHS is going to try to ban.)

Risks of Cell Phones on Airplanes

Everyone—except those who like peace and quiet—thinks it’s a good idea to allow cell phone calls on airplanes, and are working out the technical details. But the U.S. government is worried that terrorists might make telephone calls from airplanes.

If the mobile phone ban were lifted, law enforcement authorities worry an attacker could use the device to coordinate with accomplices on the ground, on another flight or seated elsewhere on the same plane.

If mobile phone calls are to be allowed during flights, the law enforcement agencies urged that users be required to register their location on a plane before placing a call and that officials have fast access to call identification data.

“There is a short window of opportunity in which action can be taken to thwart a suicidal terrorist hijacking or remedy other crisis situations on board an aircraft,” the agencies said.

This is beyond idiotic. Again and again, we hear the argument that a particular technology can be used for bad things, so we have to ban or control it. The problem is that when we ban or control a technology, we also deny ourselves some of the good things it can be used for. Security is always a trade-off. Almost all technologies can be used for both good and evil; in Beyond Fear, I call them “dual use” technologies. Most of the time, the good uses far outweigh the evil uses, and we’re much better off as a society embracing the good uses and dealing with the evil uses some other way.

We don’t ban cars because bank robbers can use them to get away faster. We don’t ban cell phones because drug dealers use them to arrange sales. We don’t ban money because kidnappers use it. And finally, we don’t ban cryptography because the bad guys it to keep their communications secret. In all of these cases, the benefit to society of having the technology is much greater than the benefit to society of controlling, crippling, or banning the technology.

And, of course, security countermeasures that force the attackers to make a minor modification in their tactics aren’t very good trade-offs. Banning cell phones on airplanes only makes sense if the terrorists are planning to use cell phones on airplanes, and will give up and not bother with their attack because they can’t. If their plan doesn’t involve air-to-ground communications, or if it doesn’t involve air travel at all, then the security measure is a waste. And even worse, we denied ourselves all the good uses of the technology in the process.

Security officials are also worried that personal phone use could increase the risk that remotely-controlled bomb will be used to down an airliner. But they acknowledged simple radio-controlled explosive devices have been used in the past on planes and the first line of defence was security checks at airports.

Still, they said that “the departments believe that the new possibilities generated by airborne passenger connectivity must be recognized.”

That last sentence got it right. New possibilities, both good and bad.

Security as a Trade-Off

The Economist has an excellent editorial on security trade-offs. You need to subscribe to read the whole thing, but here’s my favorite paragraph:

The second point is that all technologies have both good and bad uses. There is currently a debate about whether it is safe to install mobile antennas in underground stations, for example, for fear that
terrorists will use mobile phones to detonate bombs. Last year’s bombs in Madrid were detonated by mobile phones, but it was the phones’ internal alarm-clock function, not a call, that was used as the trigger mechanism. Nobody is suggesting that alarm clocks be outlawed, however; nor does anyone suggest banning telephones, even though kidnappers can use them to make ransom demands. Rather than demonising new technologies, their legitimate uses by good people must always be weighed against their illegitimate uses by bad ones. New technologies are inevitable, but by learning the lessons of history, needless scares need not be.

Disrupting Air Travel with Arabic Writing

In August, I wrote about the stupidity of United Airlines returning a flight from Sydney to Los Angeles back to Sydney because a flight attendant found an airsickness bag with the letters “BOB” written on it in a lavatory. (“BOB” supposedly stood for “Bomb on Board.”)

I received quite a bit of mail about that. Most of it was supportive, but some people argued that the airline should do everything in its power to protect its passengers and that the airline was reasonable and acting prudently.

The problem with that line of reasoning is that it has no limits. In corresponding with people, I asked whether a flight should be diverted if one of the passengers was wearing an orange shirt: orange being the color of the DHS’s heightened alert level. If you believe that the airline should respond drastically to any threat, no matter how small, then they should.

That example was fanciful, and deliberately so. Here’s another, even more fanciful, example. Unfortunately, it’s a real one.

Last month in Milwaukee, a Midwest Airlines flight had already pulled away from the gate when someone, the articles don’t say who, found Arabic writing in his or her copy of the airline’s in-flight magazine.

I have no idea what sort of panic ensued, but the airplane turned around and returned to the gate. Everyone was taken off the plane and inspected. The plane and all the luggage was inspected. Surprise; nothing was found.

The passengers didn’t fly out until the next morning.

This kind of thing is idiotic. Terrorism is a serious problem, and we’re not going to protect ourselves by overreacting every time someone’s overactive imagination kicks in. We need to be alert to the real threats, instead of making up random ones. It simply makes no sense.
