NoPolyCop,

   Your position would seem to be quite different from the moderator.  Perhaps that is because you have seen a bit as an LEO of specific issue cases solved, but object to the use in the P.E. setting based on an examiner with a bad personality you met.  It seems you allow for the reality that there are some good examiners (no different than good cops / and bad cops), and that there are those employed who want to provide your department with no less than the best applicant for the few jobs  ie; the best use of the tax payers money.  

  The polygraph records what it says it records in each respective channel.  It can not both work and not work at the same time.  Such tests take place when properly done in an environment free of artificial stimulation (noises, disruptions).  Your attempt to self stimulate to create a new reality simply causes an unknown variable which either is too weak when poorly done, too aggressive causing charts out of the norm and rejected.  or even if done right does not have a way to be tracked as I have seen so very few posters here who claim this, rather I / we read about those who either failed a test, or are not reapplying (Quitters).  Therefore your arguments REALLY traces back to the human element of all of this or testing environment, and not the device itself.  By the way, I have a problem with my toaster.  Sometimes despite my hunger being a constant every morning, sometimes the toast is a bit light, and on other days it is a bit dark.  Rarely, it is perfect, but I live with it and move on with my day.   I would not be so obsessed to start a website like    Anti-Toaster.com
