I'm very sorry that you've had to learn the hard way (
as I did) that polygraphy is
junk science. Many law enforcement applicants are falsely accused of deception and wrongly disqualified from employment because of the random error associated with this invalid test. The San Diego
Union Tribune reported in 2002 that some 40% of applicants fail the polygraph. Clearly, many, like yourself, are being wrongly branded as liars.
At this point, I would suggest that you write a detailed memorandum of all that transpired during the course of your polygraph examination. Next, you'll want to write a letter to the department contesting your polygrapher's false accusation of deception and demanding that the letter be included if SDPD shares your polygraph results with any other agency.
I think you'll find it therapeutic to educate yourself about polygraphy. It will help you to understand how you could have been completely candid and yet failed the polygraph. See AntiPolygraph.org's free book,
The Lie Behind the Lie Detector (1 mb PDF) for a detailed explanation -- and a thorough debunking -- of polygraphy. You might also send this book to any friends, relatives, or co-workers who may question you regarding your polygraph results.
I agree with you that someone needs to do something about the way polygraphs are being used (and abused). But that someone needs to be us. Too often, polygraph victims, fearing retaliation or blacklisting, are cowed into silence. I hope you'll consider working with us to bring about meaningful polygraph reform.
