Polygraph
Polygraph, which the general public mistakenly knows as the lie detector, is a device that can’t detect or record lies or falsehoods, but it really measures and records psycho physiological responses:
- fear that the offender will be caught in a lie or fear of discovery;
- information on the details of the event, which are known only to the offender.
Before we decide for a polygraph test, we must know the following:
- this is a subject of the voluntary principle (the person who will be tested, must consent to this testing;
- polygraph results don’t have a probative value for the further proceedings in the courts;
- not all people are suitable (polygraph can be used only on mentally and physically healthy people between 16 and 60 years old.
- it’s an extremely stressful experience;
- it takes place in several stages (pre-test interview, adaptive test, operational test, analysis and preparation of the opinion), so we need to take enough time do the test;
- it is primarily designed to protect the innocent and for the exclusion from the process and not so much for repression and search for the offender.
