O.J. allegedly failed his test, but since it was set up by his defense attorneys, the exact results may never be known.
I'm saying that when you pass a test administered by a law enforcement agency, you have a pretty good presumption of innocence. If I were on a jury I would need a lot of hard evidence to convict.
If I remember correctly an estimated 5% of the top FBI agents in the U.S. can't pass an FBI administered lie detector test.
Something along the lines of maybe 25 FBI agents out of the top 500 failed the lie detector test.
Which is ironic,because if you can't pass a lie detector test when you are applying for a job at the FBI, the FBI will refuse to hire you.
