Government’s decision to press ahead with implementing polygraph testing at the island’s ports of entry to help stem the flow of illegal weapons is getting the thumbs up from a US-based special agent, who is assuring Customs and other border control workers there is nothing to fear.Trebor Randle, Special Agent-in-charge of the Atlanta Office of the Georgia Bureau of Investigation, told Barbados TODAY it could serve as a useful tool in helping Barbados and the rest of the region bring an end to the importation of illegal weapons.Polygraph testing and computer voice stress analysers are used by law enforcement in some parts of the world.“The Caribbean should not shy away from the use of polygraphs. It is a very valuable tool,” said Randle.
