I took a pre employment polygraph seven years ago and although I "passed" I can say it was a horrible experience, so much so I still cringe to this day.  I can remember coming out of it feeling like a complete piece of s#$t and feeling that I had no business even considering becoming a cop.  I did not get the job but with perseverance I got on later with another department (with no polygraph required).

I have since conducted investigations where I have asked subjects to submit to a polygraph.  In my experience I have spoken at length with polygraphers and observed many polygraphs.  I have come to the opinion that the polygraph procedure is ONLY useful in eliciting confessions, due to the fact that most are scared sh#@less and have been psychologically destroyed and as a result confess.  Although I have not seen false confessions (I sincerely hope) I have seen some deemed deceptive when really not and as a result their name and credibility destroyed.   

One especially comes to mind. The file was a theft of a laptop computer.  The person was a suspect due to right time, place and opportunity.  I observed the polygraph and saw the man psychologically destroyed by the process, with his results being deceptive.  Basically he was accused as being a liar and a thief which had major job consequences.  Approx six months later the computer was found stored in a closet in the place of employment, he had "NOTHING TO DO WITH IT".   

It did not matter, the damage was done.  His credibility was long since destroyed.

I am looking to change employers, however I will never submit to another polygraph exam.  They are junk and the risks are to high.   It saddens me to see how this junk science is being used and lives destroyed.

I've taken three as a cop.  The last time I sat down for one, (after researching the subject thoroughly) I refused to sign the hold harmless agreement, telling him that I did not believe the polygraph was accurate, and that I was not giving up the right to sue in the event his results were not accurate.  He then refused to give me the polygraph, even though I told him that I was willing to take the test, just not give up my right to sue.  It was rather amusing.

Riggs,

Thank you for your candid statement.  People need to hear it.  If a police detective asks you to take a polygraph to "eliminate" you as a "suspect", they are NOT being honest.  In fact, they are being a bit deceptive,  They really just want a chance to interrogate you without a lawyer present to coerce a confession.  Hopefully, not a false confession.

If the suspect knows they had absolutely NOTHING to do with the crime under investigation, they have nothing to gain by taking a polygraph.

OTOH, if the person has been FORMALLY CHARGED the police can still interrogate the suspect with a lawyer present.
