The smugglers' greed and impatience could be to blame for the drug bust.
"Criminal groups must balance efficiency of their operations with security," said David Bright, a criminologist and forensic psychologist at Flinders University. An increase in efficiency often comes at a cost to security, he added.
"Shipping 11,000 pounds in a single shipment is much more efficient than splitting the shipment into 10 different loads requiring perhaps 10 separate ships, crews, etc." he said. "However, shipping so much of the drug in a single shipment increases the risk that the entire shipment will be seized, whereas splitting a shipment into multiple smaller shipments enhances the probability that at least some of the shipments will avoid detection."
Other factors likely played into the smugglers' decision to ship so much cocaine at once.
"The size of the load probably reflects prior bribery and Colombia's huge crop — greatly expanded since 2015," said Bruce Bagley, a professor in international relations at the University of Miami. "It also reflects high profitability in Europe," he added, "the fastest growing market for cocaine in the world that pays three times more than the US market for the same quantity."
Bagley expects the latest bust to spark a short-term shortage, driving prices even higher in Europe. However, he expects the lure of big profits to spur other traffickers to "quickly fill the void."
