Paramedic Stopped at Airport Security for Nitroglycerine Residue

At least we know those chemical-residue detectors are working:

The punch line is that my bag tested positive for nitroglycerine residue. Which is, in hindsight, totally not unexpected, since it has been home to several bottles of nitro spray that at one point or another have found their way into my pockets and then into my bag. (Don’t look at me like that—I’m not stealing the damn drug. It’s just that it’s frequently easier to shove them in a pants pocket rather than keep fishing for one at the bedside or whatever, and besides, we’ve now gone to single-patient use sprays so that once you use one on one patient, it’s fininshed.) Whether one discharged, or leaked, or whatevered in my bag, it somehow got NTG molecules all over the place, and that’s what the detector picked up. The guy said this happens all the time but I’m not so sure, and in any event I’m not even remotely certain how I could go about getting the NTG residue off my bag so this doesn’t happen in the future. NTG spray has a pretty distinctive smell. All I can smell in my bag is consumer electronics, so it must have been some minute amount somewhere.

Airport Security Confiscates Rock

They already take away scissors. Can paper be far behind?

Here’s the story:

In retrospect, I suppose I could have put the grapefruit-sized specimen inside my sock, swung it around my head like a mace, charged the cabin and attempted to hijack the flight. This, of course, never occurred to me until the zealous inspector declared my rock a “dual-use” item.

“What, pray tell, is a dual-use item?” I asked. I’m afraid I chuckled just a little, causing her to glare, withhold a satisfactory answer and call her supervisor. He hefted my rock, scrutinized it for a moment, and agreed that my specimen was indeed a dual-use item, meaning a potential low-tech weapon. During those uneasy moments when I thought I would be detained, I wondered if a doctor’s stethoscope would also be declared a dual-use item, since it could be used to strangle a pilot.

We can’t keep weapons out of prisons. We can’t possibly keep them out of airports.

No-Fly List

60 Minutes has a copy:

60 Minutes, in collaboration with the National Security News Service, has obtained the secret list used to screen airline passengers for terrorists and discovered it includes names of people not likely to cause terror, including the president of Bolivia, people who are dead and names so common, they are shared by thousands of innocent fliers.

[…]

The “data dump” of names from the files of several government agencies, including the CIA, fed into the computer compiling the list contained many unlikely terrorists. These include Saddam Hussein, who is under arrest, Nabih Berri, Lebanon’s parliamentary speaker, and Evo Morales, the president of Bolivia. It also includes the names of 14 of the 19 dead 9/11 hijackers.

But the names of some of the most dangerous living terrorists or suspects are kept off the list.

The 11 British suspects recently charged with plotting to blow up airliners with liquid explosives were not on it, despite the fact they were under surveillance for more than a year.

The name of David Belfield who now goes by Dawud Sallahuddin, is not on the list, even though he assassinated someone in Washington, D.C., for former Iranian leader Ayatollah Khomeini. This is because the accuracy of the list meant to uphold security takes a back seat to overarching security needs: it could get into the wrong hands. “The government doesn’t want that information outside the government,” says Cathy Berrick, director of Homeland Security investigations for the General Accounting Office.

When are we going to realize that this list simply isn’t effective?

Screening People with Clearances

Why should we waste time at airport security, screening people with U.S. government security clearances? This perfectly reasonable question was asked recently by Robert Poole, director of transportation studies at The Reason Foundation, as he and I were interviewed by WOSU Radio in Ohio.

Poole argued that people with government security clearances, people who are entrusted with U.S. national security secrets, are trusted enough to be allowed through airport security with only a cursory screening. They’ve already gone through background checks, he said, and it would be more efficient to concentrate screening resources on everyone else.

To someone not steeped in security, it makes perfect sense. But it’s a terrible idea, and understanding why teaches us some important security lessons.

The first lesson is that security is a system. Identifying someone’s security clearance is a complicated process. People with clearances don’t have special ID cards, and they can’t just walk into any secured facility. A clearance is held by a particular organization—usually the organization the person works for—and is transferred by a classified message to other organizations when that person travels on official business.

Airport security checkpoints are not set up to receive these clearance messages, so some other system would have to be developed.

Of course, it makes no sense for the cleared person to have his office send a message to every airport he’s visiting, at the time of travel. Far easier is to have a centralized database of people who are cleared. But now you have to build this database. And secure it. And ensure that it’s kept up to date.

Or maybe we can create a new type of ID card: one that identifies people with security clearances. But that also requires a backend database and a card that can’t be forged. And clearances can be revoked at any time, so there needs to be some way of invalidating cards automatically and remotely.

Whatever you do, you need to implement a new set of security procedures at airport security checkpoints to deal with these people. The procedures need to be good enough that people can’t spoof it. Screeners need to be trained. The system needs to be tested.

What starts out as a simple idea—don’t waste time searching people with government security clearances—rapidly becomes a complicated security system with all sorts of new vulnerabilities.

The second lesson is that security is a trade-off. We don’t have infinite dollars to spend on security. We need to choose where to spend our money, and we’re best off if we spend it in ways that give us the most security for our dollar.

Given that very few Americans have security clearances, and that speeding them through security wouldn’t make much of a difference to anyone else standing in line, wouldn’t it be smarter to spend the money elsewhere? Even if you’re just making trade-offs about airport security checkpoints, I would rather take the hundreds of millions of dollars this kind of system could cost and spend it on more security screeners and better training for existing security screeners. We could both speed up the lines and make them more effective.

The third lesson is that security decisions are often based on subjective agenda. My guess is that Poole has a security clearance—he was a member of the Bush-Cheney transition team in 2000—and is annoyed that he is being subjected to the same screening procedures as the other (clearly less trusted) people he is forced to stand in line with. From his perspective, not screening people like him is obvious. But objectively it’s not.

This issue is no different than searching airplane pilots, something that regularly elicits howls of laughter among amateur security watchers. What they don’t realize is that the issue is not whether we should trust pilots, airplane maintenance technicians or people with clearances. The issue is whether we should trust people who are dressed as pilots, wear airplane-maintenance-tech IDs or claim to have clearances.

We have two choices: Either build an infrastructure to verify their claims, or assume that they’re false. And with apologies to pilots, maintenance techs and people with clearances, it’s cheaper, easier and more secure to search you all.

This is my twenty-eighth essay for Wired.com.

The Onion on TSA's Liquid Ban

“New Air-Travel Guidelines”:

Elaine Siegel, Sales Representative
“Thank God. I don’t think I’d be able to make one more flight from New York to Chicago with a mouthful of shampoo.”

Alex Hunter, Surveyor
“The ban was a necessary precaution. We have to be willing to make these kinds of sacrifices if we’re going to prevent scientifically impossible terrorist attacks.”

Ed Johansen, Systems Analyst
“By giving passengers renewed access to these gels, lotions, and shampoos, we run the risk of creating a very dangerous and highly evasive super-slippery terrorist able to avoid all manners of restraint.”

Bomb or Not?

Can you identify the bombs?

In related news, here’s a guy who makes it through security with a live vibrator in his pants.

There’s also a funny video on Dutch TV. A screener scans a passenger’s bag, putting aside several obvious bags of cocaine to warn him about a very tiny nail file.

Here’s where to buy stuff seized at Boston’s Logan Airport. I also read somewhere that some stuff ends up on eBay.

And finally,Quinn Norton said: “I think someone should try to blow up a plane with a piece of ID, just to watch the TSA’s mind implode.”

Antiterrorism Expert Claims to Have Smuggled Bomb onto Airplane Twice

I don’t know how much of this to believe.

A man wearing a jacket and carrying a bag was able to sneak a bomb onto a flight from Manila to Davao City last month at the height of the nationwide security alert after Britain uncovered a plot to blow up transatlantic planes.

The man pulled off the same stunt on the return flight to Manila.

Had he detonated the bomb, he would have turned the commercial plane into a fireball and killed himself, the crew and hundreds of other passengers.

The man turned out to be a civilian antiterrorism expert tapped by a government official to test security measures at Philippine airports after British police foiled a plan to blow up US-bound planes in midair using liquid explosives.

In particular, if he actually built a working bomb in an airplane lavatory, he’s an idiot. Yes, C4 is stable, but playing with live electrical detonators near high-power radios is just stupid. On the other hand, bringing everything through security and onto the plane is perfectly plausible. Security is so focused on catching people with lipstick and shampoo that they’re ignoring actual threats.
