Polygraph operators have to go through the charade of polygraphing each other in order to keep up appearances. But it's a ritual of mutual masturbation, with a happy ending guaranteed for all. Unless...

Unless the polygrapher in question has offended the poobahs of polygraphy. In that case, all bets are off. That was the case for retired CIA polygrapher John Sullivan, whose memoir of his three decades with the CIA's polygraph division greatly displeased his former colleagues. When he submitted to a CIA polygraph "test" in connection with post-retirement contract work, he flunked:

This is the only case I know of where a polygrapher failed to pass a polygraph examination.

Here are two recent examples of blatant abuse perpetuated by these thugs/bullies aka polygraphers!

This is exactly why I have been fighting the use of this insidious Orwellian instruments of torture called the polygraph and why I have been trying for almost forty years to stop the bullies and thugs who administer these so-called "lie detector tests".

The polygraph test is the most important test any of you will ever take. Until you take one, you have no idea how traumatic and grueling it can be - it is that way for a reason. The polygraphers want you to be so frightened that you "spill your guts". In fact, many people are so intimidated that they make statements that the polygrapher will use to incriminate them - some people are so frightened that they confess to things they haven't even done! 

There are millions of people who have been falsely branded as liars, simply because they had a nervous reaction when they answered a question. They have had their lives ruined because they believed the lie that the polygraph was reliable and accurate as a "lie detector", and that the polygrapher was an honorable professional who would treat them fairly. They found out the hard way that the polygrapher was just an interrogator - that the polygraph was just a prop he used to frighten and intimidate them. And worse yet, that the polygrapher could accuse them of lying without any evidence to prove that accusation and they could not challenge or appeal his decision! That's not fair, it is not the way things should be done in this country, but that's the way it is - and that's the way it will continue to be until we put a stop to it!  Shame on anyone who administers these "tests" - and shame on the government for continuing to allow this state sponsored sadism!
