Ken Blackstone is the expert regarding polygraph examinations-
since 1979
- he has been involved in more than 23,000 polygraph examinations
as an examiner, consultant, and expert witness
- he has conducted more than 15,000 examinations
These have included:
- criminal examinations in areas such as rape, child sexual
abuse, shaken baby syndrome, homicide, and domestic violence
- post-conviction sex offender and post-commitment examinations
- civil disputes such as divorce, child custody, and parenting
agreements
- corporate issues such as sexual harassment, workplace violence,
fraud, and contract disputes
- issues such as standards of practice and patient care
Ken Blackstone’s experience and familiarity with all applications
of the polygraph makes him a valuable consultant and member of
a forensic team.
- He provides confidential consultation to both attorneys
and forensic psychologists in all states regarding polygraph
procedures used in the evaluation of accusations of rape, kidnapping,
homicide, child abuse, molestation, sexual harassment, and
shaken baby syndrome, and during sex offender management and
civil commitment proceedings.
Ken Blackstone has found that attorneys and forensic experts
relying on polygraph are often unaware of the fact that even
though the techniques are standardized and the instrument remains
the same, the reliability of the application varies. While his
comprehensive reports on the reliability of an examination sometimes
stand alone and are sometimes incorporated into other reports,
they sometimes require testimony.
He has testified over 100 times as an expert witness in depositions
and in Federal, Civil, and Superior Court. This has included
testimony during the guilt phase as well as during preliminary
hearings, sentencing hearings, habeas hearings, and parole hearings.
