Battlefield Lie Detector

This is a great new tool for troops to use when conducting sweeps after an IED attack or ambush.  A portable lie detector:

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.”

Troops are generally smarter than a lot of people (there's a lot of moonbats, right?) give them credit for.  They'll know this is just a tool and not perfect, but having it give a positive will definitely make them take a closer look at the person suspected of lying.

It would be interesting to see these used in hospitals as well.  I can't tell you how many times I've had a diabetic swear to me that they've been following their diet and the HgA1C result comes back elevated as hell.  Or doing an intake on somebody who swears they don't use street drugs and their urinalysis comes back positive for cocaine and marijuana.  Show them the results and they almost always look down and say, "Yeah, I really didn't mean to lie."  (huh? Isn't that another one?  Yep.)

1 The problem with lie detectors  is that what they really measure is the level of anxiety.  So  Ahmed Tikriti may be all nerved up because he knows that  Hussein Anbari planted the bomb, and has just lied to the soldiers about that; or he may be all nerved up because he's being questioned by the soldiers even though he has nothing to do with the bomb.

That's why lie detectors aren't actually useable in criminal trials.

2 They can also be spoofed through medications (Valium or Ativan, for example) and training using biofeedback.  As an imperfect tool, it's still betting than relying solely on gut feelings.  The linked article mentions how these things will be addressed, some nice foresight for a change.

I'd  like to see it used in Congress.

Too bad that's a law that'll never get passed.
