Has anyone written an appeal letter/request for another poly... have advice? Based on speaking with applicant coordinator, I know I have a very slim chance of passing on a 2nd attempt after the "parameters" letter. But since the option exists, I must exhaust all attempts.   

How much/little detail should go into the letter?

Dear Yoda,

Your appeal letter might only have a very slim chance but it is very important in any future federal applications.  You do not agree with results only based on polygraph examinations.  

The Breeze has agreed with me earlier that the polygraph used for pre-screening is subject to much debate even within the polygraph community.  I will agree with him that the value for known incident usage of the polygraph is still subject for future study and should not be cast aside.

The Breeze has agreed that videotape recordings (or DVDs) does protect the examiner and examinees.  A CD cost less than 10 cents a copy and does not take up much space for storage.  Something is wrong with the system.  There is so much that polygraph examiners and examinees agree upon.  Why can't we agree to disagree but fix known problems?

The Supreme Court agrees with you.  They will not accept any court decisions only based on polygraph examination.

There are known weaknesses within the system, let's fix them and start addressing the other questions.

Who will stop the insanity?

Regards.
