dwalin2011..... my guess he could never reach him. why do you think, seems an interesting question.
Pistone got evidence against Rastelli, they even severed him from the Commission trial so Pistone could testify. Theoretically Farruggia was Rastelli's eyes and hands out of prison, the link between him and the rest of the organization. So it's strange they could indict the imprisoned boss and low-level soldiers and made their case without indicting the middle-man as well.
