An Italian prosecutor and his 9-year-old son are under 24-hour police protection after a clan boss from the Sicilian Mafia or Cosa Nostra ordered their murders as reported by Michael Day for The Independent:
Whatever the "code of honour" mobsters claim they abide by, it certainly doesn’t prevent the killing of children. This was brutally demonstrated by the deliberate (and separate) killings of two toddlers, Nicola Campolongo and Domenico Petruzzelli, in Calabria and Puglia respectively, in the first few months of 2014.
The leading Mafia writer, Corrado De Rosa, said that these killings amounted to the "umpteenth demonstration that a Mafia code of honour does not exist."
"People often say that bosses don't touch women or children. It's not true," he said.
There are no Mafia rules and there never were; not in Italy and not in America.
