This is a fun one from the Christian Science Monitor:
Colombian drug traffickers' latest transport vehicle of choice, known as narcosubs or semisubmersibles, are made to avoid detection. Once loaded with anywhere from four to 10 tons of cocaine, only about one foot of the homemade vessels rises above water as they make the 15-day, 1,500-mile journey from Colombia's southern Pacific coast to the shores of Mexico.
Forty-two semisubs have been seized since 1993 – with three nabbed in the first week of June alone. But laws have not yet caught up with the drug traffickers.
It is still legal in Colombia to build, transport, or possess unregistered semisubmersible vessels. So, if no drugs are found in a seizure on land or at sea, there is no crime. But a bill that gives authorities the tools to prosecute anyone linked to the subs is soon to become law. Prison sentences for those convicted range from six to 14 years.
The bill follows a new law passed last fall in the United States that outlaws unregistered subs in international waters, regardless of whether they can be shown to have been carrying drugs. Typically, crews that are detected by naval authorities open an emergency valve built into the subs to scuttle the vessels and their cargo. With the evidence of cocaine at the bottom of the sea, officials had been obliged by international law to treat the crew as castaways.
...
Once the hatch is open, the nauseating smell of diesel fuel wafts from the cramped cabin where usually four men make the two-week journey: a captain, a machinist, a navigator, and a cargo representative who makes sure the cocaine reaches the buyer on the other end.
For the duration of the journey they eat canned sausages and tuna and drink Gatorade or Red Bull energy drinks. To relieve themselves, they must climb out of the cabin and tie themselves to the sub so they don't fall into the sea.
For big-time traffickers, the subs are the most efficient way to get their product to market. A single sub that slips through the dragnets can carry as much as 10 tons of cocaine. At a price of about $25,000 per kilo, the subs may carry as much as $250 million worth of merchandise.
The use of subs started being explored by some of Colombia's top drug runners in the mid-1990s, says Montoya. The so-called "go-fast" boats that tried to outrun Coast Guard patrols were being caught. The go-fasts had replaced cocaine-laden planes when they became too easy to detect.
This just illustrates the wack-a-mole aspect of the farcical "War on Drugs." The laws of the market are pretty irresistible, when demand has money, supply will find a way.
