I used to think that Fosco's stuff had the ring of truth to it, but the more I read it the more I got the feeling that he is just throwing everything that he can think of but the kitchen sink at DiFronzo and hopes that something - anything, he doesn't care what - will stick.
Agreed, the dude really hates DiFronzo, calls him an informant 5 times in every paragraph.
But I won't stop reading his stuff just when it comes to murders and things about Difronzo and Giancana take it with a grain of salt. I still like the interview with Mike Magnaficci and the ones about cerone are mostly factual
His interview with Magnaficci was great. His stuff about Cerone I take interestingly based on his relations with his children and prison visits.
