Today I’m pleased to speak about art crime in North America. It is refreshing for me not to have to introduce art crime in general—if anyone knows about it, it will be my fellow speakers. So many of us are obliged to begin talks with an introduction to art crime, because the extent of it, and the facts obscured by fiction, film, and media misinterpretation, create a screen that can be difficult to see beyond. Even the facts, presented by reputable sources like the US Department of Justice, are not always clear and coherent. They rank art crime as the third highest-grossing criminal trade worldwide, behind only the drug and arms trades. This is based on a study that my friend and colleague, Vernon Rapley, could tell you more about—it was a combined Interpol and Scotland Yard study that was also integrated into the UK Threat Assessment in 2006/2007. Another number that we hear is that art crime is worth $6 billion per year. Of course no one has any real idea, and that number is little more than an arbitrary guess. It could only reflect the estimated black market value of art registered as stolen (meaning 7-10% of its estimated auction value, which is itself an unscientific measurement). If that number is correct, then art crime cannot be the third highest- grossing criminal trade. The number is far too low, and human trafficking, even illegal traffic of plants and animals, might be considered higher. We simply don’t know, which can be frustrating—it is also one of the reasons why art crime has gone relatively understudied until recent years. Criminologists shy away from a field such as this, which lacks extensive and accurate empirical data, and relies on macro-analysis from anecdotal material and the experience of those in the field, often related orally or even through the unreliable filter of the media.
