What do you think is really going on there behind the scenes?
If I had a dollar for every theory that has been thrown out there...
Internal struggle within the Rizzuto organization, Calabrian 'Ndrangheta takeover, Haitian street gangs wanting a bigger piece of the pie, New York mob families making a move, etc.
Answer: Nobody really knows for sure yet. Pieces of the puzzle come slowly, one by one. As I've said before, it might be a combination of some of the above.
