anyone that has proof

[conner52]

Is there anyone that has taken the polygraph lied, but used countermeasures and passed?

This person apparently lied, and passed:

Yep. After getting burned for telling the truth (and having results all over the place), did something specific so I could test CMs (really, nothing left to lose). Passed every time thereafter. Identify the control questions. When being asked those questions, induce a little adrenalin rush (like the reaction you have when falling asleep and feeling like you're falling/tripping). Easy to practice. You can also get a GSR measurement device (Brookstone, Radio Shack, battery operated biofeedback with the LED display). Put a belt around your chest to simulate the pressure from the pneumatic tubes, put fingers on the device, and practice. Ten minutes later and you can beat the exam. Guarantee it.

What was the name of your device?  I can't seem to find anything but the GSR2.

You don't need to buy anything,just use the anal calibration method;  place a finger up your ass and squeeze.
