Lie detection technology and activism

I have been researching and writing about this for a lot of years regarding lie detection technology and activism.  The idea that politics and important subjects that are vulnerable to lies and deception, could potentially be sorted out with existing and potentially improved technology.

I have bought prototypes, that are not claiming to be 100% accurate by any means.  I have also researched software that insurance companies use to detect deception.

This is some information from Wikipedia on this topic;   http://en.wikipedia.org/wiki/Lie_detection

This is a video that I made about 18 months ago about technology that I am testing;  https://www.youtube.com/watch?v=RnjsadL27Ac   and this one (comedian genius Johnny Carson is the lead in this skit; https://www.youtube.com/watch?v=PjmAd8PKOCw )

Then there are the military projects that are focused on this functionality, and have been releasing prototypes that are in use in the military since at least 2008.

“The Pentagon will issue hand-held lie detectors this month to U.S. Army soldiers in Afghanistan, pushing to the battlefront a century-old debate over the accuracy of the polygraph.

The Defense Department says the portable device isn’t perfect, but is accurate enough to save American lives by screening local police officers, interpreters and allied forces for access to U.S. military bases, and by helping narrow the list of suspects after a roadside bombing. The device has already been tried in Iraq and is expected to be deployed there as well. “We’re not promising perfection — we’ve been very careful in that,” said Donald Krapohl, special assistant to the director at the Defense Academy for Credibility Assessment, the midwife for the new device. “What we are promising is that, if it’s properly used, it will improve over what they are currently doing.”

Realistically this sort of device is faulty and is bound to lack accuracy for a very long time.  So there are some questions that people need to ask themselves.

1.  Should this be allowed as admissible in court?  What is the threshold for accuracy if this type of evidence is allowed in court?   Currently polygraph testing is allowed in court, and there is a lot of scientific debate on how accurate it is as a scientific measurement of deception.  A lot of problems come with analyzing stress, and a polygraph situation can alone induce erratic stress levels.

2.  If allowed as evidence in a court case, should there be a requirement for a secondary test of at least equal accuracy be offered for good measure?

3.  What else should be offered in place of lie detection?  As it is well known that a high percentage of convicts are innocent.  So we need to be able to correct the inaccuracies and the habitual mistakes of our current system.  What would your solution be?
