Chad Dixon, a 34 year old Marion, Indiana little league coach who ran the “PolygraphExpert.net” website teaching people how to defeat polygraph tests, was sentenced to eight months in jail for threatening national security by teaching government job applicants how to beat lie-detector tests. Teaching such techniques and discussing them is not per se illegal. It is an admitted gray area in 1st Amendment jurisprudence.  However, U.S. District Judge Liam O’Grady found the evidence compelling enough that Dixon had crossed the line when he advised some clients, including two undercover officers, to conceal what he taught them while undergoing government polygraphs. This is in addition to the charges of obstruction and wire fraud Dixon plead guilty to last year.
