Guest from Canada,

There are polygraph people that support CVSA and there are polygraph people who do not support CVSA.

Some polygraph companies actually battle each other, saying that the others products, software and hardware are sub- standard.

If you look at the National Institute of Truth Verification Website you can read some CVSA testimonials.

Whats interesting is that in most of the cases that were 'solved' by the machine, the suspect confessed.

Just like with the polygraph, there are many people who confess to crimes because they believe that the CVSA test is valid.

But what happens to those who have nothing to confess, but are labled as liars?  They are just the price of American justice. 

In the Stephanie Crow murder case (Escondido CA), the victim's brother was subjected to a CVSA and confessed after hours of games by a police 'expert'.   The police hammered him and ignored reports of a prowler in the area.  In the end the prowler was caught and found to have the blood of the dead girl on his shirt.  The victim's brother is out of jail and the drifter/prowler is now being charged.

This is a prime example of how blind faith in any 'polygraph' is dangerous.  The police only followed up on the drifter after they were shamed into action by the community and bad press. 

In regards to scientific support- the polygraph has none.
The National Academy of Sciences shot down the polygraph as invalid and went as far as to say that it is a threat to national security.

LE/Intell  still use is because there are still people that confess.  They are addicted to the confessions and ignore the evidence that honest people are wrongly accused and the guilty people can pass using countermeasures. 

The polygraph/CVSA is just a business, like any other.  Once enough people realize that the product is defective and dangerous it will be recalled.

Like you said Suethem, it is nothing more than a business.  Dollars and cents.  I would be willing to bet the farm that the only polygraph people supporting CVSA are from companies with monies and interests already divuldged into the CVSA technology.  Polygraph people against the CVSA of course would have no eggs in the CVSA basket and are just trying to save their livelyhood.  It would seem to me that the CVSA technology is much cheaper to aquire than the polygraph technology as you don't have to purchase a BP cuff, chest tubes or sweat sensors.  I see a real fight in the distance.

The only problem with your line of thinking is when you look at the uphill battle we as antipoly crusaders have had trying to educate the public into seeing the lie behind the poly.  The poly has been around since the 30's and it doesn't appear to be going anywhere within the LE community for the very reasons you posted.  However, if we take the same timeline and apply it to the voice witch doctory that has surfaced, our grandchildren might see the fruits of our labor!

And when it is it will be replaced by this, from our friends to the North.

The ultimate goal upon which the justice system rests -- the search for truth -- has seen any number of sciences and pseudo-sciences come into existence. Some gradually fade away into disrepute, like hair analysis. Others -- DNA is probably the best example -- revolutionize everything from murder investigations to paternity suits.
Micro-expression analysis may be part of the next wave. Pioneered by University of California professor Paul Ekman about 30 years ago, the mapping and study of facial movements was until recently treated more as a theory than a science with tangible applications.

And the purveyor of this new "science" ???
Quote:
A television director by trade, Mr. Gough saw micro-expression analysis as a process that would allow him to marry his technical know-how with an abiding interest in law enforcement.
And then we have the next-to-the-last paragraph of the article Wink
Quote:
Only one truth-finding technique is specifically prohibited during job interviews in many jurisdictions, of which Ontario is one: polygraph testing.

The whole article is quite interesting. Read it here:
