I’ve been following developments in this theft here
It would be a sin if they had been destroyed but as Bendor points out he wouldn’t be surprised if in 5, 10 or even 20 years from now they will be ransomed back to the art gallery which I believe has happened in the past with stolen art works
UPDATE 28th November Two of the six Romanian suspects have been found guilty of taking part in the theft. They were sentenced to six years and eight months. The trial continues for the other six suspects.
