Okay, so no one is explicitly calling for body cavity searches for all airline travelers — yet. But the logic of those pushing for body scanners for all airline passengers, and criticizing the ACLU for opposing that, leads to the inescapable conclusion that these critics would support such a policy.


  1. When Richard Reid brought explosives onto an airliner hidden in his shoes, the authorities made everyone remove their shoes. When security experts and other critics pointed out that this was "silly security," defenders argued that we must put up with it in order to block that particular kind of plot.
  2. Now that a disturbed person has brought explosives onto an airliner in his underwear, panicked voices want the TSA to essentially view naked pictures of every passenger who boards an airline — that's up to 2.5 million people per day on domestic flights alone.  When the ACLU and members of Congress object, critics cry that we must abandon our personal dignity and privacy in order to block that particular kind of plot.

  3. It is far from clear that body scanners will, as so many people seem to be assuming, detect explosives concealed the way that Umar Farouk Abdulmutallab concealed them. Some experts have said plastic explosive can be concealed against the human body. It's not clear how good scanner operators would have been at detecting the "anatomically congruent" explosives Abdulmutallab hid in his underwear (let alone how consistently effective bored operators would be if these $200,000 machines were placed at every screening station in every airport for 2.5 million people a day).

  4. However, if terrorists even perceive that scanners will work, they take the next logical step and conceal explosives in their body cavities. Al Qaeda has already used this technique; in September a suicide bomber stowed a full pound of high explosives and a detonator inside his rectum, and attempted to assassinate a Saudi prince by blowing himself up. (The prince survived.)

So it seems that when the next terrorist tries to blow up an airliner using this technique, all the usual jittery voices surely will once again say that we must abandon our personal dignity and privacy in order to block that particular kind of plot. So we'd just like to get ahead of the game and state right now that the ACLU will be opposed to that.

Of course, even if body cavity searches for all were made policy, terrorists would probably shift their efforts to just hiding explosives in their carryon baggage, and the TSA's level of success in catching contraband has always been, shall we say, mixed. And reliably catching every possible means of hiding 50 grams of explosives is probably impossible given the millions of people who fly each day.

Yes, the government must zealously work to make us as safe as possible and to take every reasonable step to make sure security breaches like the ones that led to the Christmas Day attempted attack are not repeated. But we need to act wisely. That means not trading away our privacy for ineffective policies. We should be investing in developing technologies such as trace portal detectors (a.k.a. "puffer machines") that provide a layer of security without invading privacy, and in developing competent law enforcement and intelligence agencies that will stop terrorists before they show up at the airport.

Ultimately, it is up to the American people to figure out just how much privacy they want to abandon to block a few particular means of carrying out terrorist attacks. The ACLU represents those who value privacy in this debate. But when Americans make that decision, they should do so with their eyes wide open, without any illusions that this will prevent all attacks on airliners, much less attacks on shopping malls or all the infinite number of other plots and targets that terrorists could come up with if they are not stopped by competent law enforcement and intelligence agencies.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

      I agree, that language is off.  But the current push for scanners and the surprising lack of care about it in the public is quite suggestive that we could see a push for searches and other more invasive procedures in the future.

    So much of what we've been doing in airports for years has been a ludicrous song and dance that does nothing but give people an illusion of security.  The trick is trying to work towards a world where there aren't lots of people who think it's worth their life to blow some of us up.

    And this isn't a good one.

    I'm a pretty fierce left-libertarian, someone who believes in the value of the individual and the need to exclude government from our private lives as much as possible.

    But flying isn't a protected right.  You can drive, take a boat, take a bus, there are alternatives to this essential mass-transit system and if you choose to use it, you have to submit yourself to whatever universal system they choose.

    You have a choice, you don't have to fly.

    And if you do, and they mistakenly decide that this is best way to do things, it is a political mistake to oppose it.

        Heard a discussion a few weeks ago in the NY Times about a guy getting radiation therapy.  He was warned not to use the tunnels because they'd pick up his seeds.

        Scanners work by looking at density variation, and it is easy to tell what's flesh and what isn't.  So unless they create explosives that mimic the density and water content of flesh, they won't have to do this.

        And in time, scanners will only improve.

          about the efficacy and operation of scanners - this part caught my eye:

          So unless they create explosives that mimic the density and water content of flesh

          That is not on its face a particularly challenging technical exercise. Moreover, an equally obvious solution would be to make a blend that mimics the density of the polymer or cloth from which a particular garment is made.

          None of the above dissuades me that the key point remains that catching these people should become an outgrowth of good, coordinated intelligence / police work. (Which is how certain other attempted terrorist plots were averted). The TSA / Schipol reaction to broaden the scope and application of last line of defense screening technology is the wrong one, no matter the strong merits of ACLU's argument on civil liberties.

          The better answer is to stop such plots from reaching fruition. Something that Bush&Co sadly neglected.

            Tailoring (I think that's a pretty good pun in this case) an explosive to match specific densities will dramatically reduce its power, or stability.  Last thing you want is to have this go off when you're stepping out of the cab.

            And it is getting harder and harder to determine who is a terrorist.  Two out of these three "shoe bombers" were for all practical purposes British citizens.

    We could have gotten Atta and this guy BEFORE the airport and that is the ONLY way to stop all terror on planes.

    sure, wand for explosives, do what we do now, but we can't stop everything unless we stop them before they board.

    That can be done since we know it could have been done.

    scanners.  See the CNN informal poll on their web-site.  These are already in use in some airports for some flights.  Its only going to increase.  

    I have no problem with it, nor do most people.  This site will skew to the left on that issue, but even many here are pro-body scan if it means a higher measure of safety.

    We'll always be fighting the terrorist.  There will always be a new threat, and then a new technological response to the threat.  And most American's prefer that we meet the threat with technology.  

    And we will never remove all risk.  There will always be new attempts, the chance for technological and human error, etc.  But most American's will agree to give up some privacy for security.  And body scans are not body cavity searches.  I'll walk, ride bike, take a train, or drive if it comes to that.  But that is not what we are looking at here.

    •  i like the dutch way with them (0+ / 0-)

      they apparently already have the technology where it will go to a computer program first. Only if there is an anomaly will the image go to a human for a decision.

      That is one of the reasons they decide to actually use all the scanners they have so quickly.  They had been concerned about the privacy issue, that a computer program as the first image line was in seems it is ready.

      To me that is a balance between some creepy security guy looking at me naked and people stuffing explosives, taping lizards and animals to their bodies (especially endangered ones) etc. in their clothes on to their bodies.

      I have no CLUE why the US doesn't use that as well.  Instead they say the person looking at the image will be in a diff room...uhhh so? we don't get to see them laughing at our naked bodies so its better?

      That said overall i don't see a huge problem with scanners. No you can never make an aircraft totally safe but its absolute foolishness not to try as much as possible when the equipment is available to see if things are strapped to the body without an invasive cavity search.

  •  A walk-through fluoroscope unit (3+ / 0-)
    Recommended by:

    would eliminate any justification for cavity-searches.  A good unit can detect plastics and other foreign substances---even the overlapping seam lines from wrapping your thigh with layers of tape---and it'll detect the differences between flesh tissue and powders/liquids.  A top-of-the-line unit will even allow real-time videorecordings of blood-flow without barium injections.

    Now, the airlines and their insurance-carriers ought to foot the bill for these machines, since the cost of machines and operating crews is just a tiny portion of the costs related to a bombed aircraft and several hundred passengers/crew.

    If they don't want to pay up---then tell them to park the damned planes.

    Recommended by:

    The machines CAN detect a plastic explosive concealed against a human body. The reason why the machines would have trouble is because they've been modified to erase anatomical detail & allay privacy concerns.

    The technology is less foolproof at finding plastic explosives because of the modifications made to protect passenger privacy.

    The backscatter machine to be tested in Phoenix is programmed to erase anatomical details. This "edge detection" technology looks for changes in density or molecular structure on the person and draws outlines around those areas.

      But it also shows why scanner critics are trying to have it both ways.  On one hand, they use images of the old-school body scanners to claim it's a huge invasion of privacy, but they don't show you that modern scanners essentially show cartoons:


      That's what we're talking about with the modern scanners -- not exactly a "nude body" now, is it?  

      But it'd be interesting to see if it's true that the "modesty" concerns have made detection more difficult.

      Incidentally, what exactly would the scanner show with regards to, say, a clitoral hood piercing?  They're becoming a lot more common recently (a fourth friend of mine recently got hers done, and that's just of the people I know have them.)  Would that set off alarms too?

    As for #3, why doesn't someone TEST them to see if they'd be able to reveal anatomically congruent padding or plastic explosives?  Wouldn't that be the way to settle the issue?
