Fewer Than 1% Arrested From TSA's "Behavior Detection"

An anonymous reader writes "Fewer than 1% of airline passengers singled out at airports using the much vaunted 'suspicious behavior detection' techniques are arrested, Transportation Security Administration figures show. The TSA program, launched in early 2006, looks for terrorists using a controversial surveillance method based on behavior detection and has led to more than 160,000 people in airports receiving scrutiny, such as a pat-down search or a brief interview. It has resulted in only 1,266 arrests, often on charges of carrying drugs or fake IDs, the TSA said. The TSA has not publicly said whether it has caught a terrorist through the program." In related news, the odds of sanity coming to the TSA plummeted today when Schneier said he's not interested in the top job there.

      Because this program was supposed to find terrorists, not people with fake IDs or people trying to sneak a couple of ounces through security.

      If some villagers are mauled by a tiger, and I promise to catch the tigers, and I implement a system of nets and snares around the village, and I don't catch any tigers, then I have failed to keep my promise, regardless of how many snakes and wild boars I do catch.

      If there haven't been any tiger attacks in the whole time the net has been up then there's no basis to say that it has been a success or a failure.

      Well, that's a relief. I thought you were going to point to the absence of attacks as some sort of proof that this system is working, despite the complete lack of any definitive evidence, like arrests.

      You might even claim that the absence of attacks is a result of the nets being put up and therefore they have been a success.

      Oh my...looks like I spoke too soon.

      On a related note, if you're worried about tiger attacks, you can borrow my tiger repelling rock. It, like the snares, doesn't actually catch tigers, but it's guaranteed to keep them away. I myself haven't so much as seen a tiger since I began carrying it.

      Note that I'm not saying it actually has been a success,

      No, but you're certainly insinuating it rather loudly...

      I'm saying I see no example of it having failed

      As I made clear above, the complete lack of any terrorism related arrests clearly spell out the failure of this program. Either the terrorists are there, and are not being caught, or they aren't there at all, in which case the program is pointless...assuming, of course, that "capture of terrorists" was its actual goal...

      This doesn't indicate a ~1% success rate, it indicates a 100% failure rate; no terrorists were found.

    Don't make the mistake of taking their name and stated goals literally. The DHS exists solely for the purpose of keeping the US populace in fear, making us easier to control and more tolerant of increasingly draconian laws relating to "security".

    You don't know how well a detector works unless you know how many cases it failed to detect a true positive (what's called a false negative in the biz). Let's say if you searched everyone in line you'd arrest 0.2% of them for some suspected crime. In that case, the 1200 in 600k means your detector is worthless. It works no better than a random sample.

    Looking into it more, though, I learned of a larger historical context (Taken from here):

    "It is important to remember that the curses of Psalm 137 are not originally the psalmistâ(TM)s curses. They are the Lordâ(TM)s curses which the psalmist has made his own. The destruction of Edom was the fulfillment of prophecy, particularly the prophecy of Obadiah. In Isaiah 13:16, which was written about 200 years before Babylonâ(TM)s fall, the destruction of Babylon was prophesied in almost the exact terms used in Psalm 137. The destruction of the children who were too young to be transported into slavery was a common practice in ancient warfare. Since this cruelty was apparently practiced by the Babylonians during their campaigns of conquest against Israel, Babylon would receive from its Persian and Median conquerors the same treatment which it had inflicted on Israel (Jeremiah 50:29; 51:56).

    And this problem is only going to get worse with time, as more and more stupid laws are added to the books. Passing a dumb law is relatively easy, all you need is one extraordinary event ('preferably' involving a child) to make it into the mainstream media and you can pass a law against some aspect involved in that event. Getting useless or stupid laws repealed afterward is much harder.

    Personally I think every new law should come under review every 5 years to a) judge its effectiveness in reducing whatever it is it was meant to reduce, b) re-assess its applicability in light of new developments (whether that be technological, court rulings, false positives etc) and c) gauge public opinion about whether this law is still necessary. It's a lot to ask for sure, but then again passing a new law is a big deal, or at least it should be.

    Without some kind of review process like this the law books will just get thicker and thicker, until it becomes impossible to live a normal life without breaking some law every day. I'd argue we've already reached that point.
