This is a long read, but is worth it. Its rather incredible that anyone who admits or “confesses” to crimes and misdeeds to a non law enforcement examiner providing prepping them to pass a lie detector test. The rub appears in the excerpt below showing the lie-detector guy putting $$ in front of any concerns he originally had about ethics or being an accomplice to criminal activities. The feds sent in undercover officers.

“Frankly, Javier, I SMELL A RAT,” Williams e-mailed on Oct. 17. “You are doing what I told you not to do, and that is telling me that you are lying. … DO NOT SEND THE MONEY—DO NOT MAKE THE RESERVATIONS—I AM NOT GOING TO HELP YOU!!!!” When Castillo called Williams to ask him to reconsider, Williams angrily rebuffed him: “Either you’re an agent trying to set me up or an idiot. I ain’t working with either one of those guys.” But in recordings later played in court, Castillo’s repeated pleas softened Williams somewhat. He hung up saying he’d think about it.”
