In spite of the SAPS having a dedicated polygraph capacity since 1998, little research
has been conducted with regard to the use of the polygraph in criminal investigations.
Consequently, the aim of this research was to focus on the perceptions and
experiences of investigators in the SAPS regarding the application of polygraph testing
in criminal investigations, the application of the polygraph as an investigative aid, the
extent to which it is used by SAPS investigators to resolve criminal cases opened by
the general public and/or in internal departmental criminal investigations; and whether
or not it has helped to solve cases by giving direction and/or focus to the investigator
when an investigation is at an impasse.
A qualitative research approach was conducted among investigators within the SAPS.
The research design selected for this study was grounded theory. The sample
consisted of twenty investigators, ten of whom had previously used polygraph
examinations in their investigations and ten of whom had not.
Data was collected from interviews, document analysis, field notes and memoranda
which presented and detailed the perceptions and experiences of investigators in the
SAPS regarding the application of polygraph tests in criminal investigations. / Criminology and Security Science / M.A. (Criminology)
