Homeland Security testing *pre*-crime detector?

This is so ridiculous. The false positive rate is going to be crazy, there are so many issues with it, in concept... I mean, is it worth screening people for suspicious activity? Sure, they have people do that at airports in more violence-prone parts of the world, and it works. But to have a machine that's supposed to be able to, and isn't somehow going to pick up all the people who are nervous about flying, worried about their kids/spouse/dogs/etc., who are having an affair on their business trip, who have GAD, etc., etc., etc. And as someone stated in the /. comments, if you have a 99.9% false positive rate, you're just going to start waving people through, and basically profiling within the positives. Which can be gotten around, as is also talked about.

In a word... Lame.
