Seems that way, or overtime, they figured they'd store them until the heat went down and then attempted to move them. There's big money is stolen artwork like the likes of what was stolen during this heist, Rembrandt's, paintings from guys of a bygone time and era, who were long dead before the museum even begun to be built. The problem was nobody wants to be the guy who gets caught with stolen artwork in his home that he purchased off the black market.
