limit this to the top 4 of the bad guys - that they are european, back through their grandparents were all native speakers of a European language and lived (primarily) in Europe
Open til they're caught or this is known.
They all must have been European
@Wott yeah, I agree w/your critique. I was having difficulty figuring out how to divide up the space. There are clear cases where they're not European, but also clear cases where they are, and I unfortunately think it's an interesting question.
Language might be a good way to divide things, since that goes so well with culture. Perhaps something like them speaking a non-European language at home? OTOH say the thieves were all born and bred 3 generations in hollywood, native english speakers, I'd want to count that as not European.
