The drug prohibition tactic of interdiction on sea vessels fails to stop cocaine from being trafficked -- somewhere between 10 and 20 percent is seized, but the traffickers simply send more to make up for what is confiscated. In Honduras -- and many other places across the globe -- locals help traffickers recover cocaine thrown overboard to avoid detection. These Honduran locals call the tightly sealed packages of cocaine "square grouper", and they hope to find all they can.
