Man accused of teaching people to beat lie detector tests faces prison
"Whether the measures are effective is a matter of debate."<p>Less so after this prosecution.  It would be pretty stupid for the government to send undercover agents after him if his techniques didn't work.  He'd be <i>helping</i> the government if he taught ineffective techniques to people to who wanted to lie to it.  So either the government is very stupid (a real possibility, I admit) or his techniques work.
