When was that data for Italians collected? Nobody in this thread was saying that Italians in the 1990s were forming Mafia...It was about the mass immigration at the end of 19th-beginning of 20th centuries. Just look at the bigger picture: when the US imported large amounts of un-vetted immigrants, you had several ethnic based gangs. The Italian mafia was hard to get rid off once established, but in general you didn't have new ones popping up - that stopped with tougher immigration. Now the only ethnic based gangs are the Spanish speaking ones...it's such a coincidence that the latino gangs started around the time of mass immigration...
