Debates regarding the use of polygraph testing has gone a long way among professionals and scientists.

To further discuss the issue, what is your position - Are you a PRO or ANTI polygraph testing? Why?..

In my side, Polygraph examination can still be a part in Criminal Investigation, so I'm pro in it.
Well, we are always questioning about the accuracy of the test whether it detects lies or not but if we dig deeper we will acknowledge its importance. It detects physiological changes in the body- blood pressure, skin resistance, heart/pulse beat, respiration and that in way or another could possibly eliminate innocent suspects and untruthful witnesses.
Even if their is lapses in this test, we can still use it as a part of the investigation if and only if we are aware of the legal aspects like the constitutional and statutory rights of the suspect, ETC.
NOW BROTHERS AND SISTERS,why we have to eliminate one of the indispensable part of criminal investigation?

Before polygraph examination results can be used as evidence in court, a law must be made making it admissible in court. Pero pano maipapasa ang batas kung ang ibang mga mambababatas mismo ay takot na magamit ito laban sa kanila.

This is the ultimate in lie detection, DetectDeceit. There are little lies, and there are big lies. What they have in common is how readily they can be seen even without paying attention to the actual words of the liar. The shoulder shrug, the nose-touching, the hand overemphasizing with a slashing gesture, and the subtle tic in the eyes. The book taught me all of those.

I love reading criminology forum posts, too, so I can read new developments on lie detection.

Polygraphs are excellent tools but must never be entertained in court. Lie detection is subjective in many ways.
