only massino knows why he really had george whacked. some say it was also because he was underminning him with a beef with tg graziano. another reason something like george owed abunch of money to carmine rustelli, the old bosses brother. there was a few reason maybe just a threat to massinos power. perfect storm. ,maybe joe new he knew about the 3 capos hit but so did abunch of guys who were also there. massino said he had to go, but what a weakling move to act like he didnt ok. so the rizzutos wouldnt want revenge. shows he was a pussy boss you think chin or gotti would care what anyone thougth about killing one of there own.
