Ten days ago, a Banksy print valued at about $40 000 was stolen from a Canadian exhibit of the artist’s work. It was a seemingly effortless crime—a man walked in, took the work off the wall, and walked out—but then, most art crimes are. The heavy lifting comes later.

“The main rule is that it’s not that hard to steal art, even from museums, but it’s almost impossible to translate that art into cash,” says Noah Charney, a scholar and author who’s published multiple books on art theft. Paintings can be quickly cut out of frames, and small sculptures can be tucked into bags—even jewelry can be secreted away—but finding a buyer for your art or diamonds is often impossible.

“Criminals don’t understand that, because their knowledge of art crime is based on fiction and films,” Charney says.
