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 numerous 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.

The Ken Blackstone Difference

  • Ken can look at a situation, e.g., homicide, know how the examination should be done, conduct the examination, write an effective report, and testify about it under demanding cross-examination.
  • Ken can tell whether errors were made in an examination.
  • Ken's testing is open to display by videotaping:
    Division III: APA Standards of Practice (01/10/99), 3.9.8.-- An audio or an audio/video recording of the pretest and in-test phases shall be made and maintained for evidentiary examinations, in conformance with governing state and federal laws. www.polygraph.org/standards.htm
  • Due to his extensive experience with sex offenders, Ken's expertise is uniquely helpful in cases where polygraph examination results contradict the alleged victim and/or other examinations.
  • Ken is a private examiner whose work is unbiased. His testimony is about empirically based standards.
