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. 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".

You're absolutely right. While it's true that CBP targeted Chad and Doug because they were teaching people how to pass or beat polygraph "tests," their undercover agents set up other "crimes" with which to charge them (wire fraud, obstruction of an agency proceeding, mail fraud, and witness tampering). It is not a crime to teach polygraph countermeasures.
