Maybe Burnstein got one or two things wrong here and there.But the fbi has gotten a few things wrong as well.They didn't know the Chin was boss for years.It is the mafia and their intention is to be secretive.Burnstein,I believe, is the best source period for the Philly Mob.When he states he has been told by people "at high levels of the war" between Stanfa and Merlino I believe every word of it.He has worked with Leonetti and I am sure he has met and spoken with many more mobters
