Received this email, and permission to publish it from polygraph examiner John Swartz:

Jamie, I enjoyed reading your publication about "Should the Accused Take a Polygraph Examination?"

I was a Federal examiner for over 20 years, both with DEA and the Central Intelligence Agency. I have much to tell you.

In 1995, I moved back to the United States after many years in South America. I began testing sex offenders on probation in Houston and the many successes we had with that category of offender led me to give a training session to the Harris County District Court Judges in 1999.

Our felony court judges are totally on board.

They now order it for everything, including Felony DWI’s to make sure they’re not drinking and driving, etc. as well as pedophiles to make sure they have no new child victims. If they fail and admit to new violations, a MAG is filed.

It is simply a matter of training the decision makers. Train the judges and the probation supervisors and everyone and everything else falls into place.

It works to the benefit of the defense bar because those lawyers can successfully argue, "If the state can use it, so can I". And they prevail every time. We’ve won hundreds of times in front of the Grand Juries as well on everything from murder to shoplifting. If you want attorney references, I’ll give you dozens and dozens.

Incidentally, most academic studies on polygraph accuracy on specific issue criminal polygraph exams average 98-99% since 1980.

If you need more info on polys, call me any time at 713 460-3000 or hit the website at so we can discuss.

I test statewide and am in Austin, San Marcos and San Antonio every month.

  • Jamie,

    I’ll be John’s first reference. His exams have helped me get several major cases no-billed by Harris County grand juries.

  • Wendy Thomas

    I would like to discuss how to use polygraph in a defense before the grand jury and thereafter…

  • Oh my goodness! Incredible article dude! Thank you, However
    I am going through issues with your RSS.
    I don’t know why I cannot join it. Is there anyone else getting similar RSS issues? Anyone that knows the solution can you kindly respond? Thanks!!
