Laptop with Trusted Traveler Identities Stolen

Oops. A laptop with the names of 33,000 people enrolled in the Clear program—the most popular airport “trusted traveler” program—has been stolen at SFO. The TSA is unhappy.

Stealing databases of personal information is never good, but this doesn’t make a bit of difference to airport security. I’ve already written about the Clear program: it’s a $100-a-year program that lets you cut the security line, and nothing more. Clear members are no more trusted than anyone else.

Anyway, it’s easy to fly without an ID, as long as you claim to have lost it. And it’s also easy to get through airport security without being an actual airplane passenger.

None of this is security. Absolutely none of it.

EDITED TO ADD (8/7): The laptop has been found. Turns out it was never stolen:

The laptop was found Tuesday morning in the same company office where it supposedly had gone missing, said spokeswoman Allison Beer.

“It was not in an obvious location,” said Beer, who said an investigation was under way to determine whether the computer was actually stolen or had just been misplaced.

Why in the world do these people not use full-disk encryption?

TSA Proud of Confiscating Non-Dangerous Item

This is just sad. The TSA confiscated a battery pack not because it’s dangerous, but because other passengers might think it’s dangerous. And they’re proud of the fact.

“We must treat every suspicious item the same and utilize the tools we have available to make a final determination,” said Federal Security Director David Wynn. “Procedures are in place for a reason and this is a clear indication our workforce is doing a great job.”

My guess is that if Kip Hawley were allowed to comment on my blog, he would say something like this: “It’s not just bombs that are prohibited; it’s things that look like bombs. This looks enough like a bomb to fool the other passengers, and that in itself is a threat.”

Okay, that’s fair. But the average person doesn’t know what a bomb looks like; all he knows is what he sees on television and the movies. And this rule means that all homemade electronics are confiscated, because anything homemade with wires can look like a bomb to someone who doesn’t know better. The rule just doesn’t work.

And in today’s passengers-fight-back world, do you think anyone is going to successfully do anything with a fake bomb?

Cost/Benefit Analysis of Airline Security

This report, “Assessing the risks, costs and benefits of United States aviation security measures” by Mark Stewart and John Mueller, is excellent reading:

The United States Office of Management and Budget has recommended the use of cost-benefit assessment for all proposed federal regulations. Since 9/11 government agencies in Australia, United States, Canada, Europe and elsewhere have devoted much effort and expenditure to attempt to ensure that a 9/11 type attack involving hijacked aircraft is not repeated. This effort has come at considerable cost, running in excess of US$6 billion per year for the United States Transportation Security Administration (TSA) alone. In particular, significant expenditure has been dedicated to two aviation security measures aimed at preventing terrorists from hijacking and crashing an aircraft into buildings and other infrastructure: (i) Hardened cockpit doors and (ii) Federal Air Marshal Service. These two security measures cost the United States government and the airlines nearly $1 billion per year. This paper seeks to discover whether aviation security measures are cost-effective by considering their effectiveness, their cost and expected lives saved as a result of such expenditure. An assessment of the Federal Air Marshal Service suggests that the annual cost is $180 million per life saved. This is greatly in excess of the regulatory safety goal of $1-$10 million per life saved. As such, the air marshal program would seem to fail a cost-benefit analysis. In addition, the opportunity cost of these expenditures is considerable, and it is highly likely that far more lives would have been saved if the money had been invested instead in a wide range of more cost-effective risk mitigation programs. On the other hand, hardening of cockpit doors has an annual cost of only $800,000 per life saved, showing that this is a cost-effective security measure.

From the body:

Hardening cockpit doors has the highest risk reduction (16.67%) at lowest additional cost of $40 million. On the other hand, the Federal Air Marshal Service costs $900 million pa but reduces risk by only 1.67%. The Federal Air Marshal Service may be more cost-effective if it is able to show extra benefit over the cheaper measure of hardening cockpit doors. However, the Federal Air Marshal Service seems to have significantly less benefit which means that hardening cockpit doors is the more cost-effective measure.

Cost-benefit analysis is definitely the way to look at these security measures. It’s hard for people to do, because it requires putting a dollar value on a human life—something we can’t possibly do with our own. But as a society, it is something we do again and again: when we raise or lower speed limits, when we ban a certain pesticide, when we enact building codes. Insurance companies do it all the time. We do it implicitly, because we can’t talk about it explicitly. I think there is considerable value in talking about it.

(Note the table on page 5 of the report, which lists the cost per lives saved for a variety of safety and security measures.)

The final paper will eventually be published in the Journal of Transportation Security. I never even knew there was such a thing.

Good Essay on TSA Stupidity

From Salon:

“You ain’t takin’ this through,” she says. “No knives. You can’t bring a knife through here.”

It takes a moment for me to realize that she’s serious. “I’m … but … it’s …”

“Sorry.” She throws it into a bin and starts to walk away.

“Wait a minute,” I say. “That’s airline silverware.”

“Don’t matter what it is. You can’t bring knives through here.”

“Ma’am, that’s an airline knife. It’s the knife they give you on the plane.”

Hundreds of Thousands of Laptops Lost at U.S. Airports Annually

This is a weird statistic:

Some of the largest and medium-sized U.S. airports report close to 637,000 laptops lost each year, according to the Ponemon Institute survey released Monday. Laptops are most commonly lost at security checkpoints, according to the survey.

Close to 10,278 laptops are reported lost every week at 36 of the largest U.S. airports, and 65 percent of those laptops are not reclaimed, the survey said. Around 2,000 laptops are recorded lost at the medium-sized airports, and 69 percent are not reclaimed.

Travelers seem to lack confidence that they will recover lost laptops. About 77 percent of people surveyed said they had no hope of recovering a lost laptop at the airport, with 16 percent saying they wouldn’t do anything if they lost their laptop during business travel. About 53 percent said that laptops contain confidential company information, with 65 percent taking no steps to protect the information.

I don’t know how to generalize that to a total number of lost laptops in the U.S.; let’s call it 750,000. At $1,000 per laptop—a very conservative estimate—that’s $750 million in lost laptops annually. Most are lost at security checkpoints, and I’m sure the numbers went up considerably since those checkpoints got more annoying after 9/11.

There aren’t a lot of real numbers about the costs of increased airport security. We pay in time, in anxiety, in inconvenience. But we also pay in goods. TSA employees steal out of suitcases. And opportunists steal hundreds of millions of dollars of laptops annually.

EDITED TO ADD (7/14): Seems like this is not a story.

Random Stupidity in the Name of Terrorism

An air traveler in Canada is first told by an airline employee that it is “illegal” to say certain words, and then that if she raised a fuss she would be falsely accused:

When we boarded a little later, I asked for the ninny’s name. He refused and hissed, “If you make a scene, I’ll call the pilot and you won’t be flying tonight.”

More on the British war on photographers.

A British man is forced to give up his hobby of photographing buses due to harrassment.

The credit controller, from Gloucester, says he now suffers “appalling” abuse from the authorities and public who doubt his motives.

The bus-spotter, officially known as an omnibologist, said: “Since the 9/11 attacks there has been a crackdown.

“The past two years have absolutely been the worst. I have had the most appalling abuse from the public, drivers and police over-exercising their authority.

Mr McCaffery, who is married, added: “We just want to enjoy our hobby without harassment.

“I can deal with the fact someone might think I’m a terrorist, but when they start saying you’re a paedophile it really hurts.”

Is everything illegal and damaging now terrorism?

Israeli authorities are investigating why a Palestinian resident of Jerusalem rammed his bulldozer into several cars and buses Wednesday, killing three people before Israeli police shot him dead.

Israeli authorities are labeling it a terrorist attack, although they say there is no clear motive and the man—a construction worker—acted alone. It is not known if he had links to any terrorist organization.

New Jersey public school locked down after someone saw a ninja:

Turns out the ninja was actually a camp counselor dressed in black karate garb and carrying a plastic sword.

Police tell the Asbury Park Press the man was late to a costume-themed day at a nearby middle school.

And finally, not terrorism-related but a fine newspaper headline: “Giraffe helps camels, zebras escape from circus“:

Amsterdam police say 15 camels, two zebras and an undetermined number of llamas and potbellied swine briefly escaped from a traveling Dutch circus after a giraffe kicked a hole in their cage.

Are llamas really that hard to count?

Fever Screening at Airports

I’ve seen the IR screening guns at several airports, primarily in Asia. The idea is to keep out people with Bird Flu, or whatever the current fever scare is. This essay explains why it won’t work:

The bottom line is that this kind of remote fever sensing had poor positive predictive value, meaning that the proportion of people correctly identified as having fever was low, ranging from 10% to 16%. Thus there were a lot of false positives. Negative predictive value, the proportion of people classified by the IR device as not having fever who in fact did not have fever was high (97% to 99%), so not many people with fevers will be missed with the IR device. Predictive values depend not only on the accuracy of the device but also how prevalent fever is in the screened population. In the early days of a pandemic, fever prevalence will be very low, leading to low positive predictive value. The false positives produced at airport security would make the days of only taking off your shoes look good.

The idea of airport fever screening to keep a pandemic out has a lot of psychological appeal. Unfortunately its benefits are also only psychological: pandemic preparedness theater. There’s no magic bullet for warding off a pandemic. The best way to prepare for a pandemic or any other health threat is to have a robust and resilient public health infrastructure.

Lots more science in the essay.
