PORT OF SPAIN, Trinidad - t is rather worrisome that acting Police Commissioner Stephen Williams should have chosen to fulsomely praise fired national security minister Jack Warner. “He has been an exceptional minister, and I want to put that on record,” Mr Williams told the media last Monday. Even in the normal course of affairs, the Commissioner of Police should refrain from expressing an opinion about any minister of national security. This is because, although the minister sets policy, the office of the CoP is supposed to be non-partisan. To praise or criticise the holder of that office would therefore give an impression of political bias.
