That maybe be true, BUT and it's a big But the Port Authority is a Separate Entity a not controlled by the Government in fact the Port yield more control. So who cares about the headlines that's not who he met with.
Please link back to my chart. The Bahamas has a score nearly equal to the US. Is there some corruption in both countries? Of course. Here in the US it runs from small, like bribing local officials to dump sludge to large, like Senators caught with their hand in the till.
However, you stated that it is the most corrupt island in the Caribbean. Which according to your own DD is patently false. Period.
