I was considered by many in the field of Voice Stress Analysis an innovative expert. I have testified in open criminal courts as an expert for both prosecution and defense.


I found the story of interest. Their technique of test and question formulation is questionable.

This brings up interesting legal questions. Since the Supreme court has held up law enforcements right to lie to gain information, will it be legal for the suspect to use a similar device when being questioned ?

I tried Phil's technique and believe me he is the worst in the business. Do not waste your money on his "fly by night" cheap Ebay equipment practices....

Patent issued on 9/11/2012. I saw Mr. Sprague's touch screen system and tried it out. It caught me lying and I attempted to fool the touch screen.

SHE'S the one that killed Laci and had every motive to do so. She wanted Scott but he didn't want her and so she decided that if she couldn't have him then NO ONE would. I don't understand why SHE was never a suspect in the case or even questioned about where she was on the day Laci disappeared.
