I have read William Roemers book on Accardo "The Genuine Godfather" but its been a while. I recall in there something saying Accardo didn't like Bonanno- and yeah it had something to do with the Arizona conflict of interests. Plus, didn't Joe Bonanno write a book and do TV interviews about his lifestyle? That was totally against Accardo's style-to be very low key. He probably had a personal dislike for all that.
