This link to a story in Spiegel International Online offers this juicy first paragraph:
The Vatican’s attorney general Nicola Picardi released the astounding statistic at the start of 2007: The tiny nation’s justice department in 2006 had to contend with 341 civil and 486 criminal cases. In a population of 492, that measures out to 1.5 cases per person — twenty times the corresponding rate in Italy.
How ironic is it that Vatican City has the highest per capita crime rate? Apparently, a lot of it is the result of pilgrims, tourists, and visitors to St. Peter’s Cathedral. And besides, Vatical City is completely surrounded by Italy, which has developed a reputation in recent years for brazen pickpocketing and victimization of visitors.
