I have heard the same (with the help of the US Coast Guard is what I've heard), but I have my doubts as to the completeness before Disney got involved (hard to keep drug runners off a desserted island unless you are willing to constantly patrol it or occupy it - and Bahamian military spending doesn't seem quite up to the task of patroling all their desserted islands) and perhaps the order of events (did Disney's interest spark the Bahamian government - did financial contributions help?). Maybe I'm just jaded. Maybe I'm just enamoured of the idea of mercenaries with MK47s and mouse ears on their helmets shouting FOR MICKEY!!!!!
