FairChance,
Just a little over 2 years ago, I proposed (on this site) recording polygraphs without the knowledge of the polygraph/interogator. I have since...applied for an le job, took the civil service test, physical exam, polygraph, psych eval, completed the training and am happily employed (best career change ever).
I have very strong opinions against polygraph use as a hiring tool. Myself and others had very little problems "passing." I have yet to meet anyone from my academy who claims to have been 100% honest. And on a side note, many instructors made many jokes about the "honest" people who made damning admissions because of their belief in the poly.
But in regards to this thread. A cell phone and memory card is all you need to get a recording of your polygraph. Only one party has to be aware of the recording...and since you are one of the persons involved, you can record anything you say or do.
The polygraph is a sham. I lied about completely irrelevant stuff just to amuse myself over the course of many hours. I was happily employed and considered most of the hiring process a "fun" diversion from my normal job. My polygrapher was extremely abrasive, deceiving, almost abusive, etc...and I just laughed at him until he finally told me that everything turned out ok and "they'd let me know..."
I truly wish I could post my poly...just so everyone could hear how ridiculous the whole thing was. I am completely certain that many people experience the same thing I did...but for whatever reason, the tea leaves did not turn out the same fate.
I could care less if they used polygraph to interrogate people...but it should be criminal to use it in a hiring process of a public service job. It is basically a legalized way to discriminate against people.

the post from 2 years ago...i would have never guessed how much life could change. it is so funny to me that people actually believe they can hook a piece of picture frame wire to my finger, a garden hose to my chest, and become a god of my brain. it's all a sham. flip a coin...for those that must suffer this fate...just go in and have fun with them...you'll probably pass with flying colors.
