PORT OF SPAIN, Trinidad, CMC – The main opposition People’s National Movement (PNM) Thursday reiterated its call for a foreign investigator to help determine the authenticity of a series of electronic mail that Opposition Leader Dr. Keith Rowley read out in Parliament last week as it questioned the “independence” of the police in carrying out the investigation. Attorney Faris Al-Rawi told a news conference that recent media reports that Rowley had refused to hand over his computers to the police investigators were untrue and that such media report could only have come from police sources. ““There is deep trouble in our society, this investigation has been poisoned at its very root and I am confident that the population wishes to have a transparent and expeditious investigation.
