I remember when I used to be a polygraph operator/interrogator/inquisitor/terrorist, I would use the prop of the polygraph machine to great advantage during my interrogations.

You never were a polygraph examiner.  Your behavior below is proof enough:

After running a chart, I would tear the paper from the machine and jam it right in their face, a couple of inches away from their nose, and scream at them, "Just look at this shit, you told such a big lie on that on that question that you actually slung ink all over my tie!"I would point at their increased reaction on the cardio tracing and jam my finger into the still wet red ink smearing it around like a blood stain as I traced their "reaction" with my finger.This little drama was very effective in getting a confession.Another advantage of the old analog was that even if there was no reaction to any question, you could twist the little cardio tracing centering knob and make it look like they had a gigantic reaction even when they hadn't!

You're actually proud of this behavior?  Only an unethical, incompetent/inept nitwit would engage in such behavior.  Chart manipulation and physical intimidation of an examinee.  Class act.
