When I read Phil Leonetti’s book I read that he was in the running to become boss .

Good Question. Other than the Scarfo-Riccobene war I don't know too much on how Harry operated. I know that Bruno gave him freedom as long as he gave him a tribute but other than that I'm not sure if he would have had enough support

I dont think Harry ever wanted to become boss. He just wanted to be left alone. Harry was a southwest philly guy.

Leonetti saying he wanted to become boss, was a reason to kill him and take over his rackets.

That Riccobene wanted to become boss was fruit of the paronoid head of Scarfo sr; Riccobene had his small family and was a huge drug trafficker due the Bruno ban on drugs.If Scarfo would continue to accept the tribute and don't pretend all the riccobene rackets,there would be no war because harry was old (he was born in 1909) and was a old school guy in fact don't had problem with chicken man testa but only with the greedy scarfo.

There is an interview w/Harry w/himself saying he had many ample opportunities 2 become boss through the ages but he wanted to just b on his own,hence the peace b-tween him & Bruno & his longevity in the Philly mob..as well as quoting he did not respect nor like Scarfo whatsoever. I think he would have made a reasonable boss given his experience,& seemed a likable as well as a humorous guy.

Interview easily found on you tube,just type in his name.

I seem to recall in interviews with Riccobene that he wasn't interested in being the boss and was "over" Cosa Nostra. If he became boss I'd presume he'd take a laid back attitude towards it and just focus on his own rackets. Possibly the family would disintegrate or maybe a faction would try to take over to gain power.
