Techniques for beating a polygraph are public knowledge. So how can telling people about them be a crime?
There aren't enough details in the article, but it may have to do with whether or not Chad Dixon KNEW that the people he was instructing were planning on lying to law enforcement. That would make him an accessory.
So, it may be that if you teach people in general or in the abstract how to do it, there isn't a problem.
But if you give specific people that you know are planning on lying instructions on how to avail detection, then you are breaking the law.
