A handheld lie detector is to be given to US Army soldiers in Afghanistan this month. The device, called Preliminary Credibility Assessment Screening System (PCASS), will flash red when the subject varies from what he believes to be the truth.
The defense department admits that the device is not perfect, but insists that it can help 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.
However, the National Academy of Sciences has this to say about lie detectors:
"Almost a century of research in scientific psychology and physiology provides little basis for the expectation that a polygraph test could have extremely high accuracy... The inherent ambiguity of the physiological measures used in the polygraph suggest that further investments in improving polygraph technique and interpretation will bring only modest improvements in accuracy."

This will most certainly lead to injustices. I understand the desire for such a tool especially in the middle eastern conflicts, however it simply can't be trusted.
hack26, I enjoy your wit.

If anyone needs a reliable lie detector is the White House correspondents.

This lie detector will only lead to more wrongful imprisonments like this one:
