How can someone claim this stuff to belong to him ? To whom belongs the stuff ? How can it be sold ??
If there is something hauled up at all, this stuff belongs into a museum with indication of exact point found, and where it belonged on the ship.
Reminds me of troops in Iraq plundering museums.
If private people (no others but millionaires) buy the stuff to found a museum that is one thing.
If they want it in their Frank Loyd Wright villas or some russian Datscha to show off, bomb them
