LIE DETECTOR TEST (POLYGRAPH):

     A lie detector test is based on the theory that an individual will undergo physiological changes, capable of being monitored by sensors attached to his body, when he is not telling the truth.  The Supreme Court does not put credit and faith on the result of a lie detector test inasmuch as it has not been accepted by the scientific community as an accurate means of ascertaining truth or deception.
