In The Case for Forensic Polygraph Testing in Post-Adjudication Sexual Offender Examination and Management, polygraph expert witness Ken Blackstone writes:
Proposed Solution
Forensic polygraph examination has safeguards which keep its error-rate below 10 per cent. This type of polygraph testing is frequently used in the legal, intelligence and investigative communities. As an example, the popularity of the polygraph in the Federal agencies arena is encouraged by the high caliber of training and supervision provided its examiners. Similar standards and training need to be developed and deployed in the area of post-adjudication assessment and management of sexual offenders.
