In ´ndrangheta it´s allowed for a Santista (highranking member) to report some criminals to the police in order to prevent feuds and murders.
in fact sicilian mafia members always considered ndranghetisti prone to be informants, ndrangheta is not the most secretive criminal group, since the beginning it was by far less secretive than sicilian mafia, sicilian mafia has more informant only because italian government go after it heavily after 1992
