For my two cents worth, It would seem to me that the incredible amount of money involved with drugs has to make it almost impossible to enforce laws in third world countries. A $40 Bz reward is peanuts compared to the amount of money we are talking about. I'm not saying that the police are on the take, but I would be amazed if some are not given some $s to look the other way. I have been told that you can haul $16 million worth of cocaine on one of those boats that are found abandoned floating near the north end of the island.
The drug problem has increased and whatever the answer is, it won't be easy. I would like to add, I am a large man in pretty good shape and I wouldn't confront a drug dealer on the street here at home and I sure as hell wouldn't confront one in a foreign country.
