of course the mafia has a minor role in this kind of murder, but i wouldn't sursprised it's involved
according to a sicilian mafia informant who kills kennedy are the same who wanted enrico mattei dead, who was the head of the national italian petroleum company and died in a plan crash in 1962
recently inquiries showed somebody put a bomb in the plane
according to some informants the mafia was involved in the mattei's murder, they did it to do a favour to somebody in the states
behind the murder there's some texas petroleum lobby and probably even behind kennedy one
