The Wall Street Journal has an article about a blood pressure, pulse, and sweat level measuring device being tested in US airport security checkpoints. It’s made by an Israeli Company with the delightful name of Suspect Detection Systems Ltd.
If they really want to use this to find terrorists, they’re going to have to test every single person that gets on a plane. According to the TSA, two million people fly everyday. That’s 730 million people a year. Let’s assume that 10 of them are terrorists. With a 4% false-positive rate and a 10% false-negative rate, that means 29 million innocent travelers are going to be detained as suspects, and one out of the 10 terrorists will still make it through security to conduct his or her dirty work. Is it worth it, or would the money be better spent preventing terrorism through intelligence work?
Reading this, I fully expect to sit down in one of these and have it tell me “Describe in single words only the good things that come into your mind about… your mother.” Is there any point which is too far for the US public? Even with the leading security experts in the world telling us these things do no good, we still allow ourselves to be placated with meaningless tribulations which do not catch terrorists. WTF?
