But are museums good targets?

Let's say you steal a famous painting worth millions, how are you going to resell it? These are unique pieces, people will know you are selling a stolen good or a fake, no way around it. And the illegitimate owner of the painting will have a hard time enjoying it too, if you show it off, you will get a lot of unwanted attention. In the end, it is a great way of pissing off many people, probably not a great way to make money.

Maybe you can steal and remelt gold items, but still, I don't think that museums make such good targets, not fungible enough ;)

Safe deposit boxes on the other hand often store easy to resell valuables like cash and gold. I fact, I think it would be a terrible idea to put these in museums as it would make them more attractive targets.
