If the indictments are any guide it would be bookmaking and video poker machines. Also burglaries, stolen goods, etc. You also have examples of bid rigging and getting city contracts. Still some involvement in the Teamsters Union.

I think what makes the situation in Chicago hard to read these days is the quickly shrinking core of made members. Whenever they are gone, there is no family left technically. Even if you have associates or descents of deceased members still active in this or that. We've already seen this in other cities where the family is gone.
