I have a question for those of you who have used either "the lie behind the lie detector" or "how to sting a polygraph."  I am taking a polygraph in the near future,  and I am not sure of which one to use to get information on using countermeasures.  Should I go ahead and buy "how to sting a polygraph", which comes with a DVD, or should I just stick with "the lie behind the lie detector."   Are there any differences between the two of them?  Any info would be helpful.

Why not use both? You can also use the power of your intelligence by learning how to help abolish the poly' and doing whatever you feel you can to stop the use of the poly'. Just think, if a few more people before you would have choose to do the same, you wouldn't have the unfortunate experience of dealing with the poly' now! I encourage you to not be like so many and just 'get through it', but, to take control and use your situation to help others and stop the poly' industry. Start planning now for how you will deal/react if you do not pass your exam. What would be your next step? How can you continue to work through your situation? How will you stay posative? Answering these questions to yourself now, will help you later to deal with the realities.  I hope your exam goes well for you!

the most important question is whether or not you are innocent of the matter at hand.
