As a result of an edict issued in 1931 by William Tocco and Joseph Zerilli, that members of the organization must marry the daughters, sisters, nieces or cousins of other members, in a measure to ensure loyalty, the Detroit Partnership has been affected significantly less by defections, law enforcement infiltration and infighting than other Mafia families in the United States. The crime reporter Scott Burnstein has called the Detroit Mafia "the picture of success, stability, functionality and diversification".
