As he is stating in his article
There never was a group of hired killers waiting for contracts from
the Bosses of Cosa Nostra. The main focus of all the convicted killers
was making money from the rackets.

Now that may be true but that doesn't mean that there weren't men being clipped left and right. These were stone cold killers.

Do not let Capeci or whoever wrote that article fool you into thinking these men wouldn't whack you as soon as look at you for getting in the way of their business of making $$$$ money.
