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.
How does that figure compare to random searches? Without that figure for comparison it's completely pointless saying "OMGZ TSA FAIL" because nobody ever claimed that everyone stopped would be arrested. If it gets higher arrests than random searches what's the problem?
Spelling mistakes, grammatical errors, and stupid comments are intentional.
You're right! We should extend this outside of airports, so that any jumped up minimum wage gomer with a tin badge can stop anyone they like, declare Facecrime, and use that as probable cause for an invasive search up to and including internal! I'm sure that the 99% of innocents who get Probed would also agree that the payoff is worth it, whatever the cost!
Let's start with you, shall we?
If you were blocking sigs, you wouldn't have to read this.
The TSA has not publicly said whether it has caught a terrorist through the program
Of course not - That would presume the TSA (and DHS in general) actually has the goal of stopping terrorists.
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". For proof, you need look no further than how well FEMA (once an actually useful agency) has handled various disasters since they got sucked into the DHS... Or for that matter, the TSA's record at catching weapons carried by various reporters.
The second amendment grows increasingly relevant to our society every day... And not for protection from dark-skinned foreigners, but the real "terrorists" running our country and our world.
Arrested != convicted. Oooh - someone smuggling drugs. Big national security risk there.
If this were a medical test, it would have been tossed out well before implementation based on both the false positive rate and the admission of questionable sensitivity.
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.
Most of us want to catch people doing illegal things. Fewer and fewer of us want to prevent a police state that asks people for their papers at every turn, and performs strip searches because they smiled at the camera a little funny.
I'm betting if the police just randomly grabed people off the street and subjected them to everything up to cavity searches more than 1% would be found to be carrying drugs,knives longer than the legal length, fake ID's or be found to be violating some other pisant little law.
Hell if a police officers followed any random person for a single day as they went about their blameless buisness there's close to a 100% chancethat person could be caught commiting enough "crimes" to put them away for life.
It boils down to the fact that if a law enforcement official doesn't like your face he can find some ancient law you've been violating and put you away.
160.000 people were frisked and only 1.266 were found posses something they shouldn't*. That's a hit ratio of fewer than 1%.
According to Wikipedia, by the beginning of 2008, more than 1 in 100 Americans were incarcerated, so that's more than 1% "hit ratio" if you simply searched every American for illegal drugs, fake IDs or similar. Still a decent tradeoff?
*I don't see how a person carrying pot can bring down a plane, but apprently it's already possible with nail scissors, so who knows.
The summary used a lot of words to say it doesn't work. Not that they'll stop using it unless they are made to. Honestly, all this 'using a Buick to swat a fly nonsense has to end sometime.
The thing is, if you know your entering a country that starts off on the assumption your probably a terrorist, that doesn't make people relax.
Personally I find airports immensely stressful, seriously so, to the point that I take the train if at all possible. Flying is bearable, but all that waiting around in the airport buying overpriced coffee and getting 'approved as terror free' is a deeply unpleasant experience.

Why nobody in america should ever talk to the police. ever.No matter how innocent.
You can be a criminal for possesion of a lobster, opeing a packet of cigarettes without fully destroying the tax seal and for any number of lesser known laws.
Nobody in america is truely innocent. Everyone has broken the law at some point and almost everyone breaks the law many times a day without ever knowing.
As a matter of fact, I do have something to hide. Most people would not be happy about a complete stranger going through their underwear drawer at home, why should I feel comfortable with a complete stranger going through my underwear at an airport where everyone can see? It's embarrassing and humiliating to pat someone down in public and search through their belongings when they have done nothing wrong.
I see the glass as full with a FoS of 2.
So if the government labeled your kids/spouse/parents as enemy of the state without proof you'd just kill them with no hesitation?
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.
