Put your handbags away.
I think you have a number of conspiracy theories, urban legends mixed together in one story.
The are many theories regarding Tupac and his "death", and other than the one where he is actually dead, none have any evidence except supposed
sightings abit like Elvis
There were military organisations trained in Cuba for most wars "apparantly" and both America, Malitia, and Even the Orient have been accused of
using this country as a training ground over the years.
There was a rumour that tupac was in Cuba, Mexico, Brazil and most south American countries at one time or another, the escape of his family member
was, I imagine, just tied into one for more realism.
Entertainment is a money game, and big money at that, and yes money makes the world go round. In saying that groups have tried to manipulate the
public through this medium, again apparently, just look at the rat pack and there will be a long list of reasons and conspiracies as to why they were
so successful.
I would recommend breaking your story down into elements and researching each part, there is no point just posting a load of stuff without showing you
have done a bit of research first, you'll just get flamed.
Have a look into a re-post if your find anything, including where you found it.
Best of luck
