So, ed, they told you well after the fact that you failed? The polygrapher never said anything to you as to pass or fail? That's weird. It certainly is unorthodox.
My (sort of) similar tale:
I have had 2 polygraphs done within the past year as part of my probation that I am on. One I was told I passed, and on the other I was given literally no opinion. I was never told if I passed or failed, either from the interrogator or anyone else. He seemed to be in a crabby mood that day, cussing at me once, being arrogant, and generally just being a jerk.
The second time, the same guy was very nice, and I passed. The funny thing was that he did not hook all the equipment up to me- only 2 of the 3 measuring tools. Naturally, I said nothing about it, and he was happy as a clam with me. No way he could have missed it; he uses a computer poly, and one of the fields would have been flat line or off or signaling him to hook up the equipment properly.
I have wondered if, in my case, one of 3 things could be at work: (1) that they don't actually run any CQT at all, relying on admissions or confessions only and playacting the rest, (2) that they don't care what the results are, or (3) that they do care, but hide the results from you. A (4) would be that they know -I know- their deal and just go through the motions. I guess the (3) is possible, but again, what benefit would they derive by not trying to elicit a confession from you based on a "fail" result? Even if they're lying to you, saying you failed when you didn't, it would seem a wasted opportunity.
Opinions welcome...
