Defending the polygraph, but not to find Truth

[EosJupiter]

Triple x,

Truth is, I see it all the time.  Subjects taking 2-4 breaths per second in an effort to affect the outcome of their polygraph examinations.  I believe someone else referred to these folks as "dumb asses.")  I must agree.  However, that does not mitigate the fact that there are lots of them out there...

Like I said, I talk to each of these people and explain the facts of life.  Approximately 95% of them will then drop their attempts to manipulate the test and we will then get along just fine.  The remainder are considered good candidates for a job at Pizza Hut, or the local donut shop.  Not my police department....

Nonombre,

Well good to see you stuck around for some more fun and games. Now as far as the breathing rate is concerned and other manipulations that can be effected by the subject. The person has to find his own comfortable breathing rate and level. Adaptation is the key. If you can't adapt the methods and practice to yourself then nothing will work at all. Hence you get to expel your words of wisdom on the individual you are currently interrogating, and supposedly make him stop his now obvious attempt to employ countermeasures.  But from my own experience, and other sources, you may catch a rookie, but the masters are tough.

Food for thought, Eosjupiter.  I will take that into consideration...

So nonombre.....you really had subjects who tried to take 2-4 breaths per second

My concept of eliminating the breathing data variable is to NOT alter the breathing pattern at all.  To maintain an absolute pattern without exception, even to the point of answering the question at the same point in the cycle each time for every question.  Use CMs to alter the other data and let the breathing be a mute point.

Oh... nonombre and Sergeant, just for the record, I run 5k (3.1 miles) in 22 minutes - that is three 7 min miles back to back.  

One other comment about breathe control.  I'm a master diver and on average I only take 4-5 breaths per minute when diving and I maintain that rate for up to 90 minutes.  Six breathes a minute (2 every 20 seconds) sounds like a luxury, nonombre.

Absolutely.  I have also had people walk in with the perverbial "tack in the shoe,"  dark sunglasses that they TRIED to refuse to take off ("Prescription, they said.)  I took them off and examined them.  The glasses were dime store plastic.  And my personal favorite, teeth wrapped in aluminum foil because they were told that would "confuse" the polygraph....

Nonombre,

I had a guy once swear I couldn't have caught him on the RADAR cause he had tin foil in his hubcaps...I feel your pain LOL

The next time I run an exam Ill have to wear a tin foil hat as a counter-counter measure when I put the spaghetti strainer onthe guy's head.
