Re: polygraphs, tactical moves of police.

I firmly believe that the polygraph is used by police (and other authorities) 99% to create a mood which is conducive to truth-telling, and maybe 1% to "measure the physical responses and measure changes, blah blah blah."

The old way of doing polygraphs, doubt it's changed too much nowadays:
I believe the first thing they do is get their "baseline." They take a known fact, like "which card did you take from the deck" and have the subject write down the answer. The answer is then saved, but not read by the examiner. Then they go through the whole deck of cards, asking the subject, is this the card? And INSTRUCTING the subject to say "no" each time he is asked--EVEN WHEN THEY GET TO THE RIGHT CARD, AND THE TRUTHFUL ANSWER WOULD BE "YES."

Then they check what was the real card, and go back and "read" the subject's results. They say, ah, oh, yes, I see here where you showed a reaction when I asked you about the real card, and you had to lie and say no.

THIS DEMONSTRATION IS FOR THE BENEFIT OF CREATING IN THE MIND OF THE TESTED SUBJECT, A BELIEF IN THE POWER OF THE POLYGRAPH TO DETECT LYING.

Amazing how much you can get out of an interrogee if you just convince him that you have a superior power, a power of seeing through his lies.

Again, Devil_Anse, will you be joining the David Smart search Saturday in the canyons?

Interesting.
