According to prosecutors, Dixon charged his customers $1,000 a day or more for hands-on training, advertising on his “Polygraph Consultants of America” Web site that he could help people appear to be truthful on a test, then traveling across the country to meet those interested in his services. Among his 69 to 100 clients from late 2010 to April 2012, prosecutors said, were unqualified applicants for federal law enforcement jobs and convicted sex offenders — including a former English teacher at a middle school in Rockville who was convicted of sexually abusing a 12-year-old boy and had to take polygraph tests as a condition of his parole.
Perhaps the most outlandish examples of Dixon’s training, though, came when undercover federal agents approached him for his services in late 2011 and early 2012. When one agent posing as a Customs and Border Protection applicant told Dixon his brother was a member of the Zetas drug cartel involved in “drugs, extortion, murder [and] kidnappings” — and that he routinely let his brother use his identification — Dixon told him to reference the man only as a “distant relative” and say, “Look, I don’t really know what he’s into,” prosecutors wrote.
Ginsberg wrote in court filings that Dixon trained only between 50 and 70 people and that most of them were preparing for marital fidelity polygraphs. She estimated that there are at least 30 others offering services similar to Dixon’s and that none of them have been charged.
“Mr. Dixon has done nothing that warrants the government’s attempts to make him the poster child for its newly undertaken campaign to wipe out polygraph countermeasures training,” she wrote.
George Maschke, whose Web site AntiPolygraph.org offers similar information on the flaws of polygraph testing but does not offer hands-on training, said he was troubled by Dixon’s case.
“It seems to me that they’re going after critics of the polygraph and then fabricating a crime to prosecute where there had been no crime to prosecute before,” Maschke said. “Free speech is important, and I don't think explaining to people how the polygraph works, including its vulnerability to countermeasures, should be criminalized.”
Dixon, a father of four, wrote in a letter to the judge that he was “disgusted” with himself and that he did not realize initially that what he was doing was criminal. He wrote that some of his “countermeasures” were as simple as “to relax and breathe normally on relevant questions.”
“I was so dead set in my mind that this machine was bogus and I think this mind set made me feel that what I was doing wasn’t illegal and wasn’t that bad,” he wrote.
Prosecutors have asked that Dixon serve between 21 and 27 months in prison, though preferably at the “low end” of the range. His sentencing is scheduled for 9 a.m. Friday.
