Do the British even allow the use of polygraph? The US, along with only two or three (or so) countries even allow the polygraph to be used AT ALL! Most realize the machine has way to many faults to be of any real value. Unfortunatly, here in the US many believe the machine to be an honest dectector of truth-which could not be farther from the truth!
Whether he passes any such test or not has little to do with the real use of the machine-the police use it to get as much info out of you as they can to ease their investigation-that is the real value of the machine to police.
Correct.. as per my post #64..
I did some quick google checks..
While the polygraph is most commonly used in the U.S., it is within the law of many other nations, including Great Britain..
It is presently being promoted for testing of all sex offenders before release from prison.. the idea is receiving favorable comment, and looks like the law will pass..
Britain and their commonwealth nations do not use the polygraph as extensively as american law enforcement, but it is gaining some acceptance in certain areas, especially security..
It's use seems to be dictated by circumstance, as it appears, from what I have been able to find, that it is a legal measure of law enforcement..
