CNN reports today that the drug enforcement agencies from the US and Ecuador have seized a fully operational ocean-going submarine designed for drug smugglers. (Ecuador authorities seize drug-smuggling sub)
This is the first time a real submarine was captured. But in the past few years the issue of submersible vessels has been a big problem. (Coast Guard hunts drug-running semi-subs from 2008.)
Now would it have been so difficult to refer to the submersibles in the submarine story? Context is everything to good story telling. And when the issue is global in nature and deals with drug running, more information is always better than less.
