Specific Incident Polygraph Examination
Polygraph examinations can play a very useful role in investigating a wide variety of specific incidences. As an investigative tool it is capable in providing information to the company, persons or investigators regarding the incident that in certain cases is simply not possible through any other means.
Most agencies have found that the polygraph can be used most effectively to limit the number of suspects. The results can normally indicate which person/s was involved in the investigated matter, and in some instances admissions of guilt are obtained during or after a polygraph examination.
The polygraph is a valuable aid in investigations and can
add valuable information to any investigation. The polygraph helps to focus the
investigation, and for this reason saving time, money and manpower. This
procedure helps to establish the bona fides of honest persons implicated in a
case quickly and efficiently.
Polygraph examinations can not be used as the only evidence in a case, however a polygraph test can be used at CCMA level as expert evidence.
These factors will likely include the qualifications and
experience of the examiner, whether the examiner is a member of a professional
organization, whether the examiner followed the correct protocols and
procedures, whether the examiner followed an examination technique that is
internationally recognized and whether they acted ethically and fairly
throughout these examinations.
When introduced with procedural fairness polygraph
examinations can be of great assistance in collecting information during the examination
and in the aftermath. This is why it is imperative to use an examiner that has
the qualifications and experience to not only conducted a test of the highest
quality, but also to present the evidence where applicable.
