Totally disagree with you. Joe Fosco has tried to be careful with his information and has always acknowledged that he gets it from different sources. He'll say who those sources are unless there's an agreement to keep them confidential. He had no personal grudge against Accardo. When Fosco realized that some of his biased sources were putting out false information he admitted that. He's been honest about it the whole time. Just for the record, historians make revisions all the time as they learn new things. Look at the earlier FBI files of mobsters compared to newer ones: they made revisions. And let's be honest, the Outfit structure is a bit different than other crime families, and it is confusing.
