Unlikely Gaddafi moves the gold in such an obvious way.
He would use this as a ruse to distract NATO.
The Touregs are a wild bunch and know no borders, they would extract a heavy price from Qaddafi. Burkina Faso would hardly be a safe place for that gold.
Qaddafi has 5 billion, that's 160,000 pounds of gold. He could be quite safe right now in Sirte, a busy port city on the Med. He could easily have that gold in any number of ordinary freighters that could go anywhere in the world, undetected.
The world is far too busy thinking he's a nut case.
