Let me first clarify, neither am I defending anyone nor accusing anyone in the BB house.
However, the biggest question that arises is "How credible is LVA ? "
Currently LVA is only being used in combat pilot debriefings to contest decisions made by the pilots during missions. With regards to other functions and routine day to day activities, it's credibility hasn't been proved ...
Infact, a study from the U.S department of justice showed that LVA performed badly. You can follow the link at the bottom of the post. As per the article, using Voice Stress Analysis (which is the technology behind LVA), only 15 percent of Lies about drug uses were detected in a field test of 300 arrestees. Shockingly, 8.5 percent of respondents in the test who actually spoke the truth were incorrectly classified by LVA. The article comes to the conclusion that the accuracy of VSA ( CVSA and LVA) is only 50% which is no better than the probability of flipping a coin.
BottomLine : LVA is still a nascent technology and as of now, it's accuracy is under a lot of suspicion.
