This method is time-consuming but you won't get your crime rings owned for sure. In New York, do all missions until they let you to speak to people for favors. Talk to four people (since there are four henchmen to C-Rosato), then find their kill and do it. When they're all dead and the boss is the only one alive, do the rest of the missions as the soldiers are the ones that take your crime rings. Since they are dead, they can't do this with their families.
