George, never miss an opportunity to explain that Chad Dixon and Doug Williams were *not* convicted for the crime of teaching countermeasures, but for abetting the crime of lying to government officials. It is possible, and indeed usual, to teach countermeasures without encouraging or sanctioning illegal activity.

But if you advocate, support, or teach methods for passing polygraph tests, and one of your clients announces his intention to lie during his test, your responsibility is the same as a doctor, priest, or lawyer with foreknowledge of an intended crime. If you can't deter your client from his nefarious aim, then you must report him to the authorities. Chad Dixon and Doug Williams were entrapped into failing this responsibility.

Saying that Chad and Doug were convicted of "teaching countermeasures" is tantamount to saying that a lawyer who is sanctioned for perjury or witness tampering has been punished for "practicing law".
