From what little I do know based on practical experience having only been over to work within the Bahamas 3 times in the last several years...I simply do not believe that the Bahamian government has either the resources or the knowledge to engage in any real search or recovery operations....I also think that the level of corruption prevalent within the political structure has made it impossible to mount any type of meaningful effort...layers and layers of bureaucracy, dept after dept, and multiple people, all requiring a "fee", and buy the time you reach a high enough rung on the ladder, you've spent millions of dollars, months and years, and than....nothing...new government, new depts, new people, and start the process all over again from square one.
Of course...this is just my opinion...I'm sure that the reality is much more streamlined if you just contact the "appropriate" minister or what have you... just ask them...
