One hears of all kind of measures that people use for smuggling drugs. There are small submarines that are used, people eat the drugs (put into small plastic vials) - some of which burst inside the person and can kill the courier, there are low flying planes that are used for the same, and numerous other such measures that are used for trying to smuggle drugs. After all, drug smuggling is extremely lucrative, to the extent that if some are caught, and others get through, the amount of money involved still makes the entire deal profitable.
But this method was interesting, trying to use the UN diplomatic route to try and get some cocaine through without inspection (link to article)
The UN is home to its fair share of diplomatic tussles and international scandals, but this was a very different kind of intrigue: more than 35 pounds of cocaine wound up in the mailroom of the United Nations headquarters in New York, authorities say, sent probably by someone who figured the drug would elude detection because of how it was packaged.So, the UN finds itself in the position of holding 16 kn of cocaine, which would have an extremely high value if it was ever sold.
New York Police spokesman Paul Browne said the powder, discovered January 16, was in two white bags meant to look like diplomatic pouches, stamped with a bogus U.N. logo and sent from Mexico City through a DHL shipping center in Cincinnati. But a real U.N. diplomatic pouch is blue, has a lock and features the authentic seal of the organization. By international law, those pouches are not normally inspected or opened.
