Saidme,

The fact that you make an analogy between the polygraph and the space shuttle tells me that you have absolutely no scientific background whatsoever.  Your analogys, and inability to use them properly, tell me that you don't really understand the science (what little science there is) behind the machine, or that it has no scientific validity at all in detecting deception or differentiating truth.

You think it works based soley on the confessions you obtain.  If you think your charts are indications of deception or truth I think you are either brainwashed or delusional.  

Better purchase a new pair of boots and take that uniform out of mothballs because I feel you might have to go back to humping a beat to pay the bills.
