A 69-year-old former polygraph examiner for the Oklahoma City police department has been indicted for coaching people to thwart the machines.
WSJ Law Blog (“Critic of Polygraph Tests Accused of Teaching People to Lie to Government“):
For at least the second time since 2012, the federal government has brought criminal charges, accusing someone of training people on how to beat a polygraph test.
On Friday, prosecutors announced an indictment against Douglas G. Williams, a 69-year-old man from Norman, Okla., who’s accused of coaching people “how to lie and conceal crimes” during federally administered lie-detector tests.
Mr. Williams, who operates a company called Polygraph.com, says the mail fraud and obstruction of justice charges leveled against him are an “attack on his First Amendment rights.” The indictment follows the federal prosecution of an Indiana man who received eight months in prison in 2013 after pleading guilty to similar charges.
“This indictment was brought to punish and silence me because I have the audacity to protest the use of the polygraph,” Mr. Williams said in a statement Monday.
Prosecutors alleged that Mr. Williams “trained an individual posing as a federal law enforcement officer to lie and conceal involvement in criminal activity from an internal agency investigation.” He’s also accused of training another person “posing as an applicant seeking federal employment” to trick a pre-employment polygraph examination.” The Justice Department says the two individuals paid Mr. Williams for the services and were instructed by him to deny having receiving his training.
Williams is admitting to the charges. But why is his action a crime? Polygraphs have been notoriously unreliable for decades and their results are inadmissible in court because of that. A campaign to further undermine confidence in the technology is, if anything, laudable.
I can understand it being a crime for Williams’ clients to lie under oath. But teaching people to control their nervousness during questioning.
