As the world looks on in horror as the Islamic State, ISIL (also known as “Daesh” or “ISIS”) vandalizes and loots cultural heritage objects and sites, people around the world feel helpless and wonder as to how they can halt these criminal activities. Although stopping the vandalism may require military force and may risk the health and safety of volunteers on the ground attempting to stop this behavior, the public may have an influence on the rampant looting. Looting frequently occurs because there is a market for illicit antiquities. It is the responsibility of collectors, public institutions, and other art market players not to purchase or deal in antiquities without full provenance. Buyers must do their due diligence, and they must not purchase works from conflict zones that are not accompanied with full ownership histories and official export documentation. Leila Amineddoleh discusses this topic in a recent editorial in the Guardian.
