Mr. Latimer,
  I'm sorry if you interpreted my response as an attack on you personally. It's your profession that I have a problem with. What I'm trying to say is that Polygraphist seem to give off the appearance that they are an "unbiased" part of the polygraph exam and that they are only there just to record the results. When in fact you are actually a trained interrogator that controls every aspect of the examination and are able to manipulate the results through leading (and misleading) questioning. 
  Let's face it, if there was such a machine that could determine TRUTH or LIE the world would be a much safer and better place to live in. We could could just bypass the entire trial portion of our criminal justice system by just asking the accused a few simple questions and determine guilt or innocence. Let alone what this wonder machine could do to solve a great number of the other problems in todays society. But, in reality we have a machine called the POLYGRAPH that only measures a persons heart rate, breathing patterns and sweat gland activity. And you purport to be able to tell TRUTH or LIE from that? Come on.....................

Great, the same "test" that was passed by Spy Ames, that the same government has argued(successfully) in appelate court is not reliable, is going to be used to "test" FBI agents?  Sorry Ray, but you really don't have anything but a subjective bias in determining what the actual cause of the readings are during a polygraph recording.  You "assume" they are caused by a reaction to your question, safe assumption so far.....but what is the root of that reaction?

Nate,

You and everyone else out there should be aware that "going head to head intellectually" with a polygraph interrogator is the biggest waste of time you can engage in, and an impossibility.

The interrogation will NOT be a good faith exchange, but an attempt to intimidate, wheedle, cajole, coax, and pressure you into a confession using any tool available, including distortion of your words, lies, half-lies, and trickery.

If accused of deception by a polygraph examiner, the innocent person should assert their innocence and politely walk out the door.

Yes, you guys are probably right, it would not be wise to argue with and examiner because it would be a no win situation if he is dishonest about his agrument.  Although on the last test that I took, I talked to the examiner for 2 full hours before I took the test (when he said do you have any question?....I took the opportunity).  I told him I was educated on the matter and told him everything (the complete honesty tactic).  It worked and he passed me!  My discussion on the pre-exam was basically that I was predetermined that I was going to fail because of a false positive.  It was as if I was arguing that I failed before I even failed!?! He must have believed me and passed me so I guess it worked.  I would assume that if I tried to argue after a false positive, the discussion would be different and not winnable as you guys stated.

Mark,

I was in a post-test interrogation situation myself. After the examiner finished cycling through the questions, he got up and shouted "Things couldn't look any worse than they are." I was naive about the entire polygraph interrogation procedure at the time, and was completely dumbfounded at how I could derserve winding up in such a situation after spilling my guts. [Also, during the pre-test interview, the examiner brought me to tears regarding the death of my father due to a serious illness just 6 months prior.]

The interrogation lasted for hours afterwards, and I would continue to say I was telling the truth all to be rebutted with "We know you're being deceptive and untruthful." When it became apparent that they wouldn't budge a bit, I asked to leave. They never physically restrained me, but was made to understand they weren't about the let me leave. At that point I was becoming genuinely frightened as to what going to become of me on this situation. I had no idea at the time who they were (turns out it was CIA). 

The examiner walked out of the room, and another walks in a little later and plays good cop. After he saw I was maintining I was truthful, he turns into bad cop. After a while, he leaves, and yet another examiner walks in and the whole thing starts over again. When they saw I wasn't budging, they forced me to sign some form. I completely forgot what it said, but I would have gladly signed a form saying I was Kennedy's assassin (nevermind that I wasn't born at the time....). But after that, as I'm walking out the door, the one examiner extends his hand for me to shake, which I did for some reason, and then he says "It's the worst thing you can do." Wow, words of wisdom to live by. I stayed in there for 5 hours, all too see if in fact I had only smoked pot once in my life (as I reported in my clearance form -- arguably, one of the dumbest things I've ever done (the reporting of the act, not the act itself!).

I was indeed completely naive about polygraph interrogations, and now would do things completely differently. Instead of doing what Gino and Mark suggest, I fed the examiners' fetishes by passionately maintaining I was truthful and letting this thing drag on for hours and hours. What a waste of time. I wish I could tell the IRS that I'm refusing to pay the $1200 in federal taxes I owe, and that they should reimburse ME. I can only assume these examiners will one day pay dearly.

Mark,

I was working for a government contractor at the time, and not for the agency itself.

My earlier post was unclear about the handshake issue, my apologies. Here's what happened to the best of my recollection. As he was accompanying me to the door out of the main suite, we had a brief exchange of words. I was telling him how I wouldn't change my story because it was the truth. Once we got to the door, he extends his arm to shake my hand. I actually shook it, and as we're shaking, he says "It's the worst thing you can do" in reference to my not admitting to more than one experience with marijuana.

Of course, by this time, I had been in there for 5 hours, wanted nothing more than to get out, and would have done anything to be let out. He knew this full well, and took advantage of it to disparage me by, in effect, forcing me to shake his hand. What a guy. I'll bet he joked about it that night with his poly-buddies over a few beers.

Indeed, examiners are a most unprofessional bunch. I base that statement on my own experience and that of my former colleagues at my old job who endured similarly. 

The one potentially useful skill I've learned from this is how to act during questioning by law enforcement if I'm wrongly suspected of a crime. Now, I'm privy to their tactics and know when they've reached the point of pounding on you till you tell them what they want to hear. You're there when they say "Ok, we're going to go over all of this again." That's when you say: "This interrogation is over, and unless you arrest me, I'm leaving immediately."

You got to be kidin right?  We all know the examiner will pass Freeh before he even steps into the room.  I would assume this might be the case in all the exams they do “internally”.  This will be a tactic to "falsely ease" the feelings of the American people about their safety.

    Come on.....Does he really think that he is going to dupe his entire organization into believing that he was given an unbiased polygraph examination? I presume that the majority of Special Agents have enough common sense to believe otherwise. How can you have one of your own Agents give the Director a polygraph? This makes no sense at all! I hope the media brings this farce into light.
