As a writer, I’ve interviewed many Cosa Nostra members, including Philip Leonetti, the former underboss of the Philadelphia Cosa Nostra crime family who became a cooperating government witness; Ralph Natale, the former boss of that crime family who became a cooperating government witness; and Michael Franzese, a former New York Colombo Cosa Nostra crime family captain who walked away from the criminal life and became a Christian public speaker and author.
