Now way in a million years would Testa been able to put a crew together and whack Scarfo unless NY gave the ok. NY never would have, especially due to him being so damn young. The only thing that would of saved Salvie Testa is if he grew up and NY, not philly. Of course he would never of been made that young had he been around ny.
I also dont think Salvie would have been able to go to NY and talk to Castellano; i just cant imagine that ever happening. His torso would still be in staten island.
