@GaryMartin thanks a lot. By the way how are you?Long time no see. Regarding Accardo...as you said he was a quite smart guy who always removed himself from a dangerous situation more than few times. But he wasnt always like that. Maybe he larned his lesson after the meat scandal and later the tax trial but even during that period some of the top guys such as Ricca and Giancana made the same mistake, meaning, having contacts with low level associates. Ricca paid the price by going to trial and so he had to tell on Cerone, who in turn took the rep so the old boss can walk away free. No wonder Cerone's nickname was "lackey". As for Walsh and company such as Brodkin or Bieber, these guys sometimes also acted as recruiting team for the syndicate.

@Slick also thank you for the additional info. I totally forgot about that case.
