I'm sure this has been well covered before but;

How come Testa + Senter didn't stay with the Gambino's after Roy's death ?

I know what Casso book says about Reznikov killing.
But, there must be more to it.
Why didn't Gambino's want them ( or kill them otherwise)??
What happened to Gaggis crew? I know they were all in legal trouble but was it disbanded?

Varios crew was very strong in that area and in the car stuff.

** actually I'm very dubious as to Casso's claim to set Roy up. I reckon it was Gaggi and the twins. Although that doesn't answer how the twins joined the luchesses. (sp)
