Der Spiegel reports that the sovereign Vatican has the highest per capita crime rate in the world:
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.
Most of that, of course, comes from tourists, not full-time residents. Bill Donohue does not appear to have weighed in on this yet. Tim Cavanaugh surveyed the farthest reaches of the anti-defamation-of-anyone movements in our Dec. 2002 issue, and the Catholic Church is prominently featured therein.
UPDATE: And the Vatican has held this grim record for a long time–as noted way back in 2003 by Jesse Walker on this very page.
