nightowl,

Based on your account, it appears that you have not at this point been disqualified on account of your polygraph results (since your polygrapher states that a background investigation will be forthcoming).

Nonetheless, it might be appropriate for you to send (by certified, return-receipt mail) a letter to the officer in charge of recruitment contesting the polygrapher's opinion that you were untruthful. For tips on how to proceed, see Chapter 5 of The Lie Behind the Lie Detector.

on the 9/11 i took a polygraph for the Henrico county police force/Virginia.  i was nervous because i did not know what to expect. anyway, i took the test. i thought everything went well .i told the investigator everything he wanted to know because i had nothing to hide.  the test was over and i was led to a room to  wait for a few minutes.  after about 10 mins he returned for me, took me back to the room. he said on two questions my readings were questionable. "have i ever used,transported,possessed drugs ? -the answer ofcourse is NO!-he grilled me for about 10 mins then said that the reading was inconclusive and he would "give me the benefit of the doubt" 
the other question : Have i ever stolen anything from my work place like clothes or  money ? again the answer is NO!
he also said that there was a spike  and that he will have to get me for that one 

i asked him what now, he said that they will do a background investigation 
i said GOOD! because i know that anyone they talk to like  friends, teachers, bosses, anyone who knows me  knows  that i have never been involved in anything of the sort 

I am so upset!!!  and wish that there was some thing i could do because i am not guilty. I feel so bad because i know that its not true. every time i think that i might not get the job that i have wanted my entire life  i  get so depressed. i feel accused of things i have avoided my entire life.
