Staff of the Customs Anti-Narcotics Unit  (CANU) are currently undergoing polygraph testing by a staff member of a US firm and there would be changes at the unit based on the results of the tests, President Bharrat Jagdeo revealed on Wednesday at a press conference.

The president told reporters that the tests are being done to ensure that the country has a unit on which it could rely to fight drug traffickers and also to guarantee that staffers are persons of integrity.

“So there are going to be changes there based on the result of the polygraph … the members are all undergoing polygraphing at this point,” he said. However Jagdeo withheld the name of the company conducting the testing, saying he would disclose it subsequently.

Commonly known as the lie detector test, polygraph testing utilizes a  polygraph which is an  instrument that simultaneously records changes in physiological processes such as heartbeat, blood pressure, respiration and electrical resistance (galvanic skin response or GSR).
