What are the procedures of a polygraph test in the Vaal Triangle ?

A polygraph test is not as simple as connecting wires and finding results. It is quite an intricate operation that can only be performed by highly qualified specialists as there are thousands of little signs and evidence that could be lost or misinterpreted if performed by an unqualified person.
