The U.S. Department of Justice effectively conceded that polygraph countermeasures are effective in arguing against incarcerated polygraph critic Doug Williams‘ motion that he be allowed to engage in polygraph-related activities during his upcoming three-year period of supervised release. DOJ’s opposition brief (PDF), filed on 10 February 2017, notes, at p. 2:
In addition to training manuals and DVDs, defendant sold in-person, confidential, “one-on-one” polygraph countermeasures training sessions. During these sessions, defendant taught clients how to pass polygraph tests even if they were lying. (emphasis added)
The brief, which largely recaps details of the government-orchestrated “crimes” for which Williams was convicted, concludes by arguing that “the restriction on polygraph-related activities for the full term of supervised release is the minimum restriction necessary to protect the public.” This flies in the face of the polygraph community’s claims that sophisticated polygraph countermeasures can be routinely detected and are ineffective.
