The lie detector you'll never know is there


Nice little tool ... so here they are observing a street looking for "signs of stress that might mark someone out as a terrorist or suicide
bomber" and you walk along following to the side of this blond bird.

You know it's wrong, those thoughts, those desires but the smell is too much ... you just have to turn to her and say ...

"BANG BANG BANG" ... rings out through the crowded street and you fall dead ... innocent like one young south American man in London a short time back.

The shocked young lady is wondering what on earth is going on but a well armed police officer assures her everything okay now the terrorist is
dead and wow wasn't she lucky ... and can I help you?

You were only going to say how beautiful she was and ask her to have lunch with you.

Yep this new technology could really be useful .. I wonder how the police officers lunch went.

The lie detector you'll never know is there

05 January 2006
From New Scientist Print Edition

THE US Department of Defense has revealed plans to develop a lie detector that can be used without the subject knowing they are being
assessed. The Remote Personnel Assessment (RPA) device will also be used to pinpoint fighters hiding in a combat zone, or even to spot signs of
stress that might mark someone out as a terrorist or suicide bomber.

In a call for proposals on a DoD website, contractors are being given until 13 January to suggest ways to develop the RPA, which will use
microwave or laser beams reflected off a subject's skin to assess various physiological parameters without the need for wires or skin
contacts. The device will train a beam on "moving and non-cooperative subjects", the DoD proposal says, and use the reflected signal to
calculate their pulse, respiration rate and changes in electrical conductance, known as the "galvanic skin response". "Active combatants
will in general have heart, respiratory and galvanic skin responses that are outside the norm," the website says.

Because these parameters are the same as those assessed by a polygraph lie detector, the DoD claims the RPA will also indicate the subject's
psychological state: if they are agitated or stressed because they are lying, for example. So it will be used as a "remote or concealed lie
detector during prisoner interrogation".

But finding ways to fulfil the DoD's brief will pose a practical challenge, says Robert Prance, an electrical engineer at the University
of Sussex, UK, who specialises in non-invasive sensors. "They might capture breathing rate with an infrared laser that senses chest vibration, but how they will measure a pulse through clothes, for instance, is a very big question."
“The device will be used as a concealed lie detector during interrogation”

If the RPA is ever produced, it is likely to prove controversial. A remote lie detector would face even more difficulties than standard
polygraph tests, which were themselves the subject of a damning 2003 report from the US National Academy of Sciences. "There is no way a
polygraph test can be carried out usefully without the subject knowing, because you actually want the person to worry about certain questions,"
says Bruce Burgess, an examiner with polygraph firm Distress Services of Leatherhead, Surrey, UK.

But Steve Wright, a conflict analyst at Leeds Metropolitan University, UK, raises the prospect of people identified as suspects by the device
being captured and subjected to secret "prisoner rendition" as a result.

And he warns that the RPA could introduce a "chill factor" into everyday life.
