INTRODUCTION.
a. The modern special agent (SA) has numerous technical investigative aids
available to assist him in his quest for the facts of a crime or incident. One of
these is the polygraph.
This is not an electrical device that detects lies or
truth, but is an instrument on much the same order as the electroencephalograph,
electrocardiograph, or the X-ray.
With it, a competent polygraph examiner can
ascertain truth or deception.
b. In order for the SA to obtain the greatest value from the polygraph,
he should know its capabilities and limitations; the assistance he can render
the examiner; and the directives and regulations pertaining to its use.
Remember that a polygraph instrument can only be of value when utilized
