Ya i gotta think pre commision trial they they wouldve gotten involved. But during the 90s who wouldve gotten involved? Gotti who did the same exact thing(or was he already in prison when this was happening?), vic and gas psycho asses, and the both the bonnanos and the columbos didnt really have enough influence to do anything. And the only reason i can think about the chin not getting involved is maybe the geneveses were somehow profiting from all the chaos like they did after the bruno hit.
