Polygraph, Sex Offenders and the Court
by: Ken BlackstoneAbout a century ago, Dean John Wigmore, Northwestern University School of Law, hypothesized that if “there is ever devised a psychological test for the valuation of witnesses, the law will run to meet it.” But his prophesy has yet to prove itself. In fact, it often seems that the law has been running away from the polygraph. In his new book, Ken Blackstone explains that this has less to do with the validity of the polygraph and more to do with the lack of a bright line between forensic and utility polygraph.
