I think the question here was why if all people was he chosen as a shooter on the Galante hit.
His father and uncle were dead at the time.
That’s an important hit
It should have only went to someone that was trusted.
From what I read after the 3-captains hit he was looked upon as a junkie.
Maybe they planned on whacking him after the hit, but he got locked up and they weren’t able to get to him?
You've got the timeline the wrong way around, Galante was killed two years before the three captains. Bruno was made a captain after the Galante hit but was taken down
later when his father, Giaccone, and Trinchera were killed. They wanted to kill Bruno and his uncle JB Indelicato after the three captains to prevent retaliation, but the contracts expired. They were then allowed back in and put in Massino's crew.
JB is also still alive.
