In regards to the Gallos, I think that they would have started trouble anyway. Especially Joe Gallo. Al Gallo seems to have fit in well in later years, Larry Gallo died of throat cancer but there was an attempt on his life. Joe Gallo was just looking for trouble in my opinion. Right up until his death he was feuding and drawing a lot of attention to himself and the mob. I ff he had not been killed in Umbertos it would have gotten worse with him.
