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.
