People from Bonanno to Buscetta have made it clear that not everyone who gets made has to have participated in a murder. There were people with prestige positions, such as attorneys, politicians, physicians and even priests who were made members but had no need to be called to kill. Frank Desimone, the boss of the Los Angeles Family from 1956-67 was a licensed, practicing criminal attorney who probably never pulled the trigger on anyone. He's only one example and there are plenty of others.
