I don't live in the USA so I can't make any claims about the American mob, but over here where I live there are a lot of serious guys involved in organized crime that are not publicly known names. I figure that if it's like that in a bumfuck place where I live, there must be a lot of the same things happening in places like NYC, Chicago or Detroit.
As long as you're not actively involved in the life, you can never actually know what's going on and who's involved.

Organized crime is a shadow world in itself. What the public knows and what the media can tell you is only scratching the surface.
