Nude Awakening

The dangerous naked machines.

Last summer, I watched a fellow passenger at Washington’s Reagan National Airport as he was selected to go through a newly installed full-body scanner. These machines--there are now 40 of them spread across 19 U.S. airports--permit officials from the Transportation Security Administration (TSA) to peer through a passenger’s clothing in search of explosives and weapons. On the instructions of a security officer, the passenger stepped into the machine and held his arms out in a position of surrender, as invisible millimeter waves surrounded his body. Although he probably didn’t know it, TSA officials in a separate room were staring at a graphic, anatomically correct image of his naked body. When I asked the TSA screener whether the passenger’s face was blurred, he replied that he couldn’t say. But, as I turned to catch my flight, the official blurted, “Someone ought to do something about those machines--it’s like we don’t have any privacy in this country anymore!”

The officer’s indignation was as rare as it was unexpected. In the wake of the failed Christmas bombing of Northwest Flight 253, the public has been overwhelmingly enthusiastic about these scanners. A recent USA Today poll found that 78 percent of respondents approved of their use at airports. Western democracies have been no less effusive. President Obama has ordered the Department of Homeland Security (DHS) to install $1 billion in airport screening equipment, and the TSA hopes to include an additional 300 millimeter-wave scanners. Britain, France, Italy, and the Netherlands have all made similar pledges to expand their use. (At the end of January, the European Commission's Information Commissioner, Viviane Reding, announced that in light of body-scanners' "privacy-invasive potential" and unproven usefulness, the machine should not be imposed without "full consideration of its impact.")

Let’s not mince words about these machines. They are a virtual strip search--and an outrage. Body scanners are a form of what security expert Bruce Schneier has called “security theater.” That is, they give people the illusion of safety without actually making us safer. A British MP who evaluated the body scanners in a former capacity, as a director at a leading defense technology company, said that they wouldn’t have stopped the trouser bomber aboard the Northwest flight. Despite over-hyped claims to the contrary, they simply can’t detect low-density materials hidden under clothing, such as liquid, powder, or thin plastics. In other words, the sacrifice these machines require of our privacy is utterly pointless. And, as it happens, it’s possible to design and use the body scanners in a way that protects privacy without diminishing security--but the U.S. government has failed to do so.

 

Millimeter-wave scanners came on the market after September 11 as a way of detecting high-density contraband, such as ceramics or wax, that would be missed by metal detectors when concealed under clothing--while avoiding radiation that could harm humans. The machines also reveal the naked human body far more graphically than a conventional x-ray. But, from the beginning, researchers who developed the millimeter machines at the Pacific Northwest National Laboratory offered an alternative design more sensitive to privacy. They proposed to project any concealed contraband onto a neutral, sexless mannequin while scrambling images of the passenger’s naked body into a nondescript blob. But the Bush administration chose the naked machine rather than the blob machine: Some blob skeptics argue that blotting out private parts would make it harder to detect explosives concealed, for example, in prosthetic genitalia. Of course, neither the blob nor the naked machine would have detected the suicide bombers who have proved perfectly willing to conceal explosives in real body cavities, as a Saudi suicide bomber proved in a failed attempt to assassinate a Saudi prince using explosives planted in a place where the sun doesn’t shine.

Former DHS director Michael Chertoff, whose consulting firm now represents the leading vendor of the millimeter machines, Rapiscan, has been a vocal cheerleader for body scanning: He called the Christmas bombing a “very vivid lesson in the value of that machinery.” In 2005, under Chertoff’s leadership, TSA ordered five scanners from Rapiscan, claiming that its naked images were less graphic than those of competitors. TSA also introduced one additional privacy protection: Agents who review the images of the naked bodies are in a separate room and, therefore, can’t see the passengers as they’re being scanned. According to the TSA website, the technology blurs all facial features, and, based on some news accounts, private parts have been blurred as well. But because the TSA remains free of independent oversight, it’s impossible to tell precisely how they’re being used.

Most troubling of all, the TSA website claims that “the machines have zero storage capability” and that “the system has no way to save, transmit or print the image.” But documents recently obtained by the Electronic Privacy Information Center reveal that, in 2008, the TSA told vendors that the machines it purchases must have the ability to send or store images when in “test” mode. (The TSA told CNN that the test mode can’t be enabled at airports.) Because no regulations prohibit the TSA from storing images, the House (but not the Senate) voted last year to ban the use of body scanning machines for primary screening and to prohibit images from being stored.

Sorry, I simply cannot muster any outrage about this whatsoever. What outrages me is stupidity and wasted time and resources -- doing pointless things that are supposed to make us feel like we are safe but other accomplish nothing or make things worse. On the other hand, aircraft are targets and I am much more concerned about being blown up in one than I am about being ogled on the screen of some detector.

So, to me , the question is first, second, and third a question of efficacy. And on this subject, Mr. Rosen, you are both ambiguous and disingenous, shifting rapidly between claims about utility and claims about personal dignity. The first thing to get straight is what these machines ... view full comment

The problem here is focusing on things rather than people. Our current "security theater" is a joke, and everyone who travels frequently knows it. Inevitably, whatever kind of new and undoubtedly even more expensive gizmos we come up with will be staffed by sleepy people who couldn't make the cut for Assistant Manager at Burger King looking at the same boring images hour after hour, day after day, week after week, etc. Zzzzzzzzzzzzzzzz.

On the other hand, profiling works. It is impossible to imagine that AQ could come up with someone willing to kill themselves for Allah who hasn't left a trail of involvement in radical Islamic activities. American Express is able to screen kazillions of dail ... view full comment

Agreed, RP. However, what you call "profiling" is not what ordinary people and most politicians, left and right, understand when they hear or speak the word "profiling." So when advocating the security practices you're advocating, you need to use a better, more precise word than "profiling." Because the two things that people understand the word to mean -- criminal profiling, like in the movies, and racial profiling, like in actual law-enforcement -- manifestly and provably do not work. The latter is also both illegal and a fundamental violation of civilized values. What you're talking about is neither of those.

Call it behavioral screening, or passenger analysis, or whatever, but if you cal ... view full comment

I like to name things as they are, rhubarbs. It is certainly politically incorrect to use "profiling" because it has bad connotations from news stories. But while it is absurd and abusive to stop vehicles driven by black Americans in disproportionate numbers "on suspicion", it is even more absurd to ignore the obvious shared characteristics of people who have actually committed terrorist acts. I guess we could dream up some newspeak label for what is in fact defining a typical terrorist profile and screening those who have it more carefully, but everyone will still know exactly what's going on, and I for one feel no need to make excuses for it. Most of these guys have been young male Arabs, ... view full comment

I do travel on El Al and fly in and out of Israel with some frequency. While there is no question that Israel is more sophisticated about passenger screening, these conversations, such as the one above, often suggest to the naîve that Israel does not use technical means, including screening machines and bomb detection machines. It must certainly does. There are great, big ones in the lobby of Ben Gurion airport before you even get to the counters.

On the other hand, Israel's passenger screening is not godlike in its ability to discern exactly whom to search and whom to ignore. I have had my children's luggage searched in detail when leaving the US for Israel. The searchers were very a ... view full comment

The dialogue about seems to suggest that we failed to detect the underwear bomber out of political correctness. That is not the case. We failed to detect him because, even when we had ample information in our system, we were systematically unable to analyze it and bring it to bear. That is incompetence, not political correctness. If you want to talk about political correctness, consider the fact that we have lists of undesirables that are so secret, to protect our "intelligence means," that they cannot be disclosed to airlines or ports of entry or embarkation so as actually to keep those people out. That sort of right-wing political correctness is so insufferably stupid it belongs in Ca ... view full comment

I don't think political correctness had anything to do with the last case, but that it was a combination of incompetence and trying to screen everything about everyone all the time instead of being more focused. The latter may indicate some indirect effect of bending over backwards to avoid hurting someone's feelings or appearing predjudiced, but I doubt it.

On protecting intelligence means, it's a genuine concern. If we ever figure out how to get someone inside one of these groups, or as today are getting second-hand information from agencies that have done so, it is a tightrope to walk between interdicting someone who might have dangerous intent, and by doing so exposing the source that mig ... view full comment

What would Jeffrey Rosen think of the questioning one gets before boarding an El Al flight? I suspect not much, even though the time that has passed since the inception of the questioning has corresponded with a lack of attacks on that airline's planes and passengers. Of course, this is America, and if you don't like the security, you do not have to get on the plane.

If you do not want to engage in the process that protects you and other passengers, take a boat, Nothing's perfect, but I do not think that protection of civil liberties means that we have to accept an increase in the palpable risk that someone is going to hijack or blow-up a plane.

01/29/2010 - 2:23pm EDT |

All very lovely in theory, RP, but I'm not buying. Sounds to me like it has at lot more to do with protecting the "assets" of bureaucratic regimes than protecting the nation. Of what use is the intelligence if it cannot be used to protect us from threats? To savor over tea and biscuits in Langley VA?

01/29/2010 - 4:41pm EDT |

"Most of these guys have been young male Arabs ..."

That's simple BS, and that's the problem with calling behavioral analysis "profiling." Sure, on 9/11, all of the attackers were young male Arabs. But since then, would-be attackers have tended not to be Arabs. We've had South Asians, British hippies, and polite black men. Ethnic identity, age, skin color, and national origin are obviously useless in picking these needles from the haystack of the traveling public. Using the word "profiling" encourages the political leaders who must enact policies to rely on a technique that, while viscerally satisfying to the Krauthammers of the world, is not merely useless but actually counterproductive.

I can't tell whether backscatter scanners will decrease significantly the odds of a suicide bomber getting aboard an airplane or not. That would require some actual testing, with real people trying to fool the system - of which there has been very little.

But the personal dignity argument made here is just hysterics. Get over it already - we let doctors and nurses and undertakers see us naked,and they all do far worse than anonymously scan a digitally altered picture of us for 30 seconds. I have no tears for someone so concerned about their dignity that this would be a problem - they can walk. But I do pity the poor SOB who has to sit in a phone booth and look at images of the naked bodie ... view full comment

rhubarbs--

I guess it depends on how you define "people who have actually committed terrorist acts" ie whether you include attacks outside the US, etc. I don't want to nit pick here, but a disproportionate number of Salafist, jihad-prone Muslims are in fact young male Arabs. A significant number of other terrorist profiles exist, most relevant here some of the Shi'ite groups and Iran's various Sunni proxies, Europeans of South Asian and various other ex-colonial extractions, but why pretend the data doesn't exist? We can narrow things down considerably and avoid ethnic myopia by tracking of membership and/or connections with known radical groups, but I don't want to exclude any potentia ... view full comment

RP: I'm curious as to why you posit that AQ "could conduct a Mumbai style attack every week for years if it wanted"?

Do you have a theory as to why they would refrain from this if they has the capability?

It would appear that they actually don't have that capability, otherwise we would expect them to use it. Schneir has a long piece about why he believes that suicidal terrorists are so rare (basically there are few suitable candidates, few opportunities to connect and train, and they only perform one act) in his latest newsletter.

As you say, statistically you are not going to be killed by terrorism, from which we can infer there are very few (albeit potentially very dangerous) terrorists. ... view full comment

Nari-I'd appreciate a link to the Schneir piece if you can. It does seem to be true that AQ & Co. are having increasing difficulty recruiting people who have both the will and the capability to carry out suicide missions as demonstrated by those who have been captured, including in Iraq and Israel. I remember thinking that they were beginning to scrape the bottom of the barrel a few years ago when a mentally deficient Palestinian kid was captured at an Israeli checkpoint, around the same time bombers in Iraq were found to be family rejects who had been essentially purchased, and etc.

Misdirected voices of protest! Airline hijacking invention? The PLO. Airliners as bombs after being hijacked Al Qaeda with 15 Saudi terrorists aboard. Every time we have to pass any inspection, shoes off, scanning, body scanning... Never forget to thank Islamic terror for this horror not the government trying to protect us. I prefer to be body scanned then even the remote chance to be blown up.

IowaBeauty-

Very funny, and right on. I also agree with much of the sentiment here that, setting aside the question regarding the efficacy of the scanners, Rosen's objection on privacy grounds is overwrought. Rosen himself acknowledges that 78% of persons polled on the issue said they would have no problem with the scanners. In my view, the scanners would be less intrusive than pat-downs, or than having custom's agents rifle through your luggage, as happened to my family, rummaging through our underwear, bras, condoms, tampons, etc., in order to confiscate some vacuum-packed ham that we were honest enough to declare.

RP: On an iPhone with no copy'n'paste right now, but if you google "Crypto-Gram" or "Counterpane" you should be able to find it with only a few links to follow. I think it's still the current issue of the newsletter; if not it'll be the first in the archive.

As you say, there are lots of ways to hurt us (and bring down airliners). That this is not occuring very often hopefully indicates that a) it's very hard to find the people to do it and b) the government is doing a good job catching or stopping those who are wanting to.
