By all accounts, Nino Gaggi hit the roof when he learned that Roy had whacked an innocent kid in broad daylight.

On the subject of Gravano.....

Gravano opened an afterhours club in Bensonhurst. The bar was the scene of a violent altercation one night involving a rowdy biker gang intent on ransacking the establishment A violent melee ensued in which Gravano broke his ankle and the bikers were chased off. Gravano then went to Castellano and received permission to murder the leader of the gang.
Big Paul thought that Gravano would pay someone to do the deed for him.
Castellano was flabbergasted when he later learned the crutch-ridden Gravano personally took part in the hit.
