I think with Gravano and the tapes that Gotti would have lost the case anyway BUT Cutler was not charged or disqualified was he? So it seems to be very self-serving for the government to charge you with a crime and then say you can't use the lawyer of your choice who has (fairly or not) beaten them in previous cases.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
