Coming to an airport near you:
Tested in Russia, the two-stage GK-1 voice analyzer[sic] requires that passengers don headphones at a console and answer "yes" or "no" into a microphone to questions about whether they are planning something illicit.
The software will almost always pick up uncontrollable tremors in the voice that give away liars or those with something to hide, say its designers at Israeli firm Nemesysco.
It wouldn’t surprise me if Congress tried to implement this at US airports, of course it is absolutely worthless as a security measure, but it would sure make it look like Congress was doing something. And that is the most important thing, isn’t it? That Congress looks like they are trying to do something. God forbid that they actually accomplish something, we might expect them to do it again sometime.
