yes, everything you say is true, I really don't think ricca or accardo wanted him as boss, but, he was the boss of the taylor street crews, and they were the power in the oufit. when he came back from mexico In 1975 he was hardly the same man as when he left. his health was rapidly deteriorating and he was called before a senate committee {a closed door session} investigating cia-mafia ties. whether it was aiuppa,or accardo the decision was made to make sure he didn't testify. he could not be trusted any longer.
