Stanistani sends us to MSNBC for a dyspeptic Newsweek commentary on the TSA's latest attempt to make air travel safer: the rather ominously named "Behavior Detection Officers" now working in a dozen US airports, and slated to go nationwide in 2008. They are trained in the discipline of reading "micro-expressions." The editorialist calls that a pseudo-science, but in fact it's a well-understood skill that can be taught and learned. A cursory look at this TSA program might put one in mind of Orwell's "facecrime," and that's the road the Newsweek writer goes down. Yet some who bemoan the security theater historically run by the TSA point to the gold standard of airport security, Tel Aviv airport, and wonder why TSA officers can't act more like the Israelis. Bruce Schneier wrote recently about one reason why the Israeli security model isn't completely transplantable to these shores: scale. And here's Schneier's take on behavioral profiling from a year ago. That's what the BDOs will be trying for: scrutinizing intent instead of pocket knives. Let's just hope they don't get swamped with false positives.

Okay, so you want to look only at cases where Muslim fundamentalists are trying to blow up planes, do you?

Isn't this open to abuse? (Score:5, Insightful)
I know that airport security is a tough issue, and something that needs to be done right, but allowing an interpretation of a micro-expression to be used to select people for further investigation basically gives the airport staff the option of pulling over anyone, any time under this pretext.
Do they collect statistics on how powers like this are used? In the UK, the police have had to start collecting statistics on the use of stop and search powers, because of concerns about racial profiling. The statistics have verified claims that the behaviour of the subjects is not what's being used by officers when deciding to search, the race of the subject is. Of course, this has lead to claims that the police are trying to find excuses to stop and search large parties of other ethnic group, to alter their statistics, without any probable cause (eg searching all passengers coming of a train for weapons, when they had no evidence that any existed)
I'm not necessarily against this kind of selection, but I do believe that it needs to be implemented carefully to prevent abuse and unfair treatment of certain sections of the population, so that not only is the security done right, it's seen to be done right.
Isn't the current system more "open to abuse"? (Score:5, Insightful)
They already have this option!
This is designed to make that option actually, you know, useful.
Even if you think it could be "abused", they can already effectively select anyone, for any reason, for secondary inspection. That's the whole point of trying to use some kind of behavioral cues, instead of just randomly doing it to anyone (or young blonde women), or only persons who appear to be of Middle Eastern descent.
Yes, as you say, it needs to be done right. But please read Schneier's article [schneier.com] and the New York Times story [iht.com] on the topic.

That's really where we should be heading in America, is it now?

I mean after all, that's the example the Israelis offer. It has worked so well for them so far, hasn't it.
If we really want to stop terrorism, then perhaps we should start by not dropping bombs on foreign countries and killing hundreds of civilians each week. That might be an even more effective method than assigning the gestapo to the airports.

It actually *IS* a pseudo-science (Score:5, Insightful)
There are exactly zero citations in MEDLINE and PsycINFO for a peer-reviewed study done on normal people using this technique. There's one where it was used to help people with schizophrenia learn emotional cues in others. The only other citation was a book chapter (which isn't a study).
So yes, when you have little or no science in the psychological and medical databases to back up your psychological technique, we call that a pseudo-science -- it's not a real, proven technique.
And because of this, it definitely should NOT be used at airports. There is a great deal of science showing how lousy humans are at detecting lying, including nonverbal cues.

Nope, there are publications (Score:4, Interesting)
The question isn't whether the study of micro-expressions is science or not; the question is whether particular claims or assumptions about micro expressions exceed what is scientifically defensible, particularly whether inferences made from the study of micro-expressions are reliable. They're almost certainly, in this context, not.
It all has to do with the nature of evidence. Evidence forms a network, within which inferences can be made. Any single strand of that network will tend to be unreliable.
For example, if you know a person well, you probably could use micro-expressions very effectively. If you knew a lot about what the person is doing, you probably could as well. However, as a screening test, it is bound to be extremely unreliable. Even if you catch a fleeting glimpse of anger, disgust, or contempt on somebody's face in an airport security line, even presuming you are correct, it tells you absolutely nothing about that person, other than he is angry, disgusted, or contemptuous. Anybody who has done much traveling by air is bound to feel those things from time to time.
This is the problem with all screening tests that look for something extremely rare in the general population. Even with a highly reliable test, the rate of false positives will tend to be much higher than the rate of true positives. This is the problem with random drug tests; unless you are testing for a drug that is very commonly used, you don't have a great deal of certainty from a positive test, unless you have other evidence leading you to suspect drug use.

Passengers are not the only worry for airport security. For most of modern US history, passengers have posed little concern. At the same time, the US has had many international enemies.
Airports are full of security holes. Other freight handling systems are full of security holes. "Appearing" to do things to improve security is a political strategy.

I would vastly have preferred airport security stay within the control of the airlines. Perhaps with federal "guidence". Then no question of 4th Amendment could come up.

The over-the-top security measures at our airports are simply political theater and not effective policing methods. I can't believe they still have everyone removing their shoes...thank goodness no one tried to smuggle an IED on board in a bodily orifice. And if anyone swiped MY kid's formula bottle because of some Kubrickian fear of fluids, I'd be on my way to Gitmo for attempting to bend a TSA agent into a pretzel.
Why can't they simply take a nod from Israeli Airlines and stick a guy with an Uzi on board each plane? Lord knows I've been on flights where his presence would have been welcome, if only to subdue the toothless trailer park escapee trying to open the window at 30,000 feet.
And why aren't these same security procedures in place at U-Haul? After all, they haven't always used airplanes to blow up buildings...
All of the money being spent on this bloated home security apparatus, all of the money spent keeping the military stocked with munitions, all of the money spent devising better prosthetic limbs before all of the returning veterans hobbling around begin to make 'victory' in Iraq seem a bit of an oxymoron,,,all of this money might have been better spent reducing our dependence on fossil fuels three decades ago when it first became obvious how vulnerable we were to the vagaries of Middle-Eastern politics. If we'd spent even half the money we have wasted making ourselves feel safe from threats both real and imaginary since 9/11 on alternative fuel research ten years ago, Bin Laden would be penniless and living quietly in a tent in some arid desert, pulling the legs off of scorpions for his sick amusement, instead of enjoying eternal life as the bogeyman of the 21st century.
It would be wise to remember that, througout history, many more people have been killed or imprisoned by their own government than any foreign power. It's probably not such a good idea to make it easy for them.

Israeli airport security is easily gamed (Score:4, Interesting)
Americans who are visiting Israel once or twice tend to be deeply impressed with Israeli security. Once you get used to it, however, it is easily gamed -- many of the procedures haven't changed for decades, most of the inspectors are 20-somethings making minimum wage and subject to the same levels of boredom as the TSA, and increasingly they don't have the language skills required to do a good interrogation. Once you've gone through a few times, you know what to expect and, assuming you aren't Arab and aren't "in the computer", you can pretty much choose the level of harassment you want assuming you know how to convincingly lie, which is not a particularly difficult skill to learn (and pretty much a required skill for anyone doing work in the area, on either the Israeli or Arab side). And in fact even Palestinians know quite a few ways around the system -- sure, they will be harassed, but it is fairly predictable.
I once did a business trip that involved visiting, in a two-week period, Israel, Jordan, Syria, Lebanon (illegal at the time for US citizens, though plenty were there), back to Jordan, back into Israel, Egypt, then Israel again, then out Tel Aviv. I answered lots and lots of questions about where I had been, what I had done, etc etc, lying the whole time, never once came anywhere close to getting stopped. Again, it just isn't that hard...comes with the territory, for better or worse.
Security going into Israel on carriers other than El Al is incredibly lax, worse at times than flights within the USA. So if someone wanted to try to smuggle explosives onto an airplane, in-bound would be the way to go, not out-bound through Tel Aviv. Given that the passenger profiles going into Israel are more or less the same as the profile going out, you'd make the same political statement.
So yes, it is mostly theater and pseudo-science, but makes a great first impression. And folks are making huge amounts of money "consulting" with the Dept of Homeland Security, who no one has ever accused of being the sharpest pencils in the box, on various hare-brained schemes like this.

So, does that mean I can ignore them? I mean, if they're not police, they're just regular citizens. The most they can do is talk to the airlines and ask that I not be allowed to board. On the other hand, that's a great basis for me to sue the airlines. I mean, I paid them for a service, and they're denying it. The only way out of that is, of course, to have TSA screening as a part of the contract. Or are you willing to admit that the TSA is a federal police force, and so they do have authority to arrest you or force a search upon you?
Well, that's good to know. You do realize that a lot of people at airports are there to see other people off, right? And given that airport security will screen family that's seeing someone off, I can only imagine that the TSA does as well. So, sure, the TSA isn't "out on every street". They are screening people who aren't flying, though.
In short, because the TSA is unreasonable in its security, we should expect more unreasonable security procedures and not complain about it. Yea, that's *totally* logical...
Well, since it's a fairly new program, we'll just ignore the clear absurdity of it until it rears its ugly head. I mean, it's like if tomorrow there was made a law that every second born child under 12 should be executed on sighting. Since it'd be "a fairly new program" and there wouldn't instantly be "provide[d] any instances of real people encountering problems", we'll just have to wait until the body count grows to a large enough amount to start complaining. And even if the law gets overturned, if Congress kept passing new second-born-child-execution laws, carefully worded to be different yet do the same thing, after a while we'd just have to accept that that's how things are. I mean, it's not like they'd be killing adults or the first born. Irrational tradition beats Constitutionality or sanity.

However, we must make sure the hijackers don't get control of that plane. If, by some miracle, they do get control, there must be little payoff and control must be difficult to maintain, and those facts should be publicized.
As a corollary, if getting control of a plane remains easy and the payoff is large (or perceived to be large), there is nothing you can do to keep the hijackers out. All you can do is put everyone in a TSA-approved, pocketless, uniform flight suit and disallow all carry-ons without medical certification (pre-certified, doctor authorized medicine/equipment, positive ID).
All you can do is to deny them weapons.
We are headed in this direction because of the hysterical intent to keep all undesirables off an insecure plane. If this is truly our intent, status quo in-flight security to protect the airline industry from having to spend money (or brook government influence in their business practices if the government were in charge of in-flight security), then let's forget the patronizing baby steps and go there already. Bring out the jumpsuits already!
That's the consequence of not securing the plane.
Personally, I say put sane security measures in place on the plane and let them try. We need to spend the appropriate money on in-flight security, and we need to stop hemming and hawing about how it's going to be done. If we can spend this much money trying to sponsor a failing democracy in Iraq, we can find the money for in-flight security.
