At the time, Tom(Fish Cafaro son) took his sentence so he woukdnt get clipped! At least on the surface they "split". Tom Cafaro and Barney are and were tight. Who knows if Fish and the kid have made amends, but on the surface at the time there were seperate and the kid turned his back on the old man. It got so bad for Fish at one time he refused to testify at Larca, Bellomo and Gurino trafficking trial and they threw his as in solitary for over a year at Otis!
