Polygraph

Postby PHB » Wed Jan 21, 2009 2:31 am

I would like to see an article in Blueline about the Polygraph and it's applications in criminal investigation, interrogation as well as the application process. Is the use of the polygraph on the rise or is it declining? What are the views of some of the country's agencies regarding the device? Is there a place for polygraph examiners in the civilian market after they retire?

Maybe this has been addressed in past issues?

Government loves the polygraph; not because it can detect lies inasmuch as throwing chicken bones on a Voodoo doll can muster. Rather, it represents a completely legal and voluntary means to interrogate someone, without a lawyer present, under duress with the aim of extracting information and damaging admissions that the subject would not normally reveal had the polygraph not been invoked. That's my two cents, anyways. There's a reason that polygraph tests are NOT admissable in Canada's justice system.

That's why a Blueline article on the device would be a good source of information for us LEO's who really don't know that much about the machine and how it works. Another good question would be to examine any case law surrounding the polygraph in Canada. I know they can't be used for pre-employment screening in Ontario but other than that they are used in the majority of other provinces.

I don't like to use the words "good" and "bad" in reference to the polygraph. It's definitely "useful." I do not agree with it being labeled as a lie detector either, when all it does is compare the body's physiological response to relevant, probable-lie, and control questions. Polygraphs can be beat with proper counter measures. For example, if you were asked if you have ever stolen a purse, and you answer "no," you might be completely innocent. However, your heart rate and blood pressure could sky rocket because you're reminded of the time your mom was mugged and you associate that stressful incident with purse-snatching, even though you've never stolen a purse. Do you drink more than you revealed on the pre-polygraph questionairre? You might not, but your best friend might be an alcoholic and the mere question irks you. So long as your responses to these questions are greater than your responses to probable-lie control questions (which everybody lies about), the polygraphist has no other option than to label you as deceptive. This, in essence, is how the polygraph works.

I'm sure there the polygraph is a hot button topic. From my limited experience it seemed to work fine. It would be interesting to get some people that have had firsthand experience in using a polygraph in the field to chime in.

PHB, I'll have to politely disagree with you on that one. :D Polygraphists claim a 90-95% success rate, but trained psychologists revealed a paltry 61% accuracy. To put that into perspective, most anyone off the street would score the same 61% success rate by pure chance. As I noted above, it's a great way to make people talk, and highly useful for interrogation purposes. :o As I mentioned, my only beef is that its proponents misrepresent its effectiveness and nature, rather than being truthful.

Hey all.
I have a question, after reading all this Poly staff my head hurts a little.

The question I have is:
If I became honest.. and state that:
- 17 years ago I drove a motor vehicle while I knew I had too much to drink.
- 15 years ago I change pricing on a product to pay less for it.
- 7 years ago I change pricing on 3 products to pay less.

I regret all this but it happened, cant change that.

Can I be charged with all this stuff if I simply admit to it on poly test?
Applying to RCMP we also fill the questionnaire, we sign it, thus addmit on paper with a signature.

For specific RCMP polygraph related questions you should post a question in the "Ask an RCMP Recruiter" section.

I'm resurrecting my old post regarding polygraph. I would love to see something in Blueline. I'm sure it has been in the past. Not since I have started reading though.

Have a great holidays people!
