Even if Mancuso never whacks anyone, that is NOT indicative of the mob's decline. Just because bodies aren't dropping everywhere means absolutely nothing. There are still several recent unsolved 21st Century mob hits out there, the mob still kills when it really has to. But Mancuso would be a complete imbecile to kill anyone right now. And if you ask me, mob wars within a crime family is a sign of its weakness, not its strength.
Can you name these several recent mob murders? Murders that were actually ordered by the Family and not just someone going off the reservation.
