In a move sure to bring the polygraph haters out of the woodwork, the US Army is issuing a handheld lie detector to select soldiers in Afghanistan in order to "root out potential terrorists" and help "narrow the list of suspects after a roadside bombing." The DoD isn't asserting that the device is perfect, but it's hoping the detection capabilities are accurate enough to save American lives and sniff out allegiances that may have otherwise gone unnoticed. Hailed as PCASS (Preliminary Credibility Assessment Screening System), the underlying unit is a TDS Ranger that relies on three sensors connected to a respondent and integrated software that uses Green to signify truth, Yellow if it can't decide and Red if it recognizes a filthy liar on the other end. Nevertheless, we're certain Lafayette Instrument Company is stoked about the deal -- you know, considering that the Army has already purchased 94 of 'em at $7,500 apiece.[Thanks, ladderless]
