To me this story is OT, but I have to say with the BILLIONS involved in transporting and selling drugs (even legal ones), bribes are an everpresent hazard. I doubt our government pays anything like a bribeproof salary to the people who have to enforce these laws. Cops by the hundreds have destroyed their careers by things like selling evidence they confiscate. Many more never get caught and have accounts somewhere with funds never paid them by the taxpayers.
If Americans don't think this is usual in the War on Drugs, then they are as clueless about that as about the War on Terror. Remember that the world's foremost terrorists are also the biggest drug producers. They own the heroin trade. War on Drugs and War on Terror are two subdivisions of the same multinational industry.
