OK, in the godfather series, we could know what mafia activities in 20th century (gambling, prostitution, mob, etc). But are they still use the same activity today? Or have they found another new useful crime to move on? Besides, being mafia in 21th century is not as easy as a century ago, right? They have to deal with the harsher law and cops and they won't be able to do free shootings in street again.
