The show showed that over a 7 year period, roughly from 2000 to 2007, or so the Feds were building a case specifically against Tony. He was the focal point. They had numerous rats who had Tony on tape, but all died before they could make it to the witness stand, and from what I understand, if if a witness isn't alive to verify what's on the tape, it's usually thrown out as evidence. In the case of Puss, he never got anything really incriminating on tape as is. Ray Curto did, but most of the guys who he had on tape were also dead like Ralphie and others by the time Tony goes to Holstein's. Chris is dead, so he's out as a potential witness and anything said about him on tape is kaput and even if it involved others, it can't be verified since he's dead. We never saw any of the other guys, besides presumably his crew, interacting with him, and that was before he was on Team Fed.

So, they have Carlo. Carlo answered directly to Tony, and to a lesser extent, Silvio.

Presuming Silvio never wakes up, and Tony did die in Holstein's - do they have to start from scratch?

Yes, he made a deal but pointing the finger on other guys, like Patsy or Paulie - without any wiretap evidence or wire evidence to back it up, isn't it just hearsay?

For example, the Feds had Gotti on tape discussing murders but it wasn't until they got Gravano on the stand to not only verify, but expand upon what was on the tapes, that they got him.

So, if Tony takes one at Holstein's - is the rest of the Family secure as far as indictment goes, for now?
