That's from the 1984 documentary "Crime Inc", the 1st episode. It's a little funny to hear though, when the narrator says "Perhaps Bruno was killed because he opposed drugs.
Perhaps younger men simply wanted to take over". "YOUNGER"....Tieri was not only older than Bruno, he was in a worse health shape even, since he died only a year after the hit. And Caponigro was younger...By 2 years, really a HUGE difference

A "generational conflict"!
They didn't know yet who killed him when the documentary was made though, but still, now when it's known, defining Tieri as a "younger man" compared to Bruno, when he even had to attend his RICO trial in a wheelchair with an oxygen tank....He barely made it in time to authorize the hit, but could never enjoy the profit he could get out of it...
