Sinatra , anyone who lived in bensonhurst knows all about greg and his crew, greg got away with everything, the guys above him protected him from getting killed, he brought money in for decades and killed on their orders, it was around for years he may be an informer, the gambino's were given the contract to kill him, then the colombo's called it off,circa 1989 90. he killed so much the thinking was no way he is a rat..this guy was pinched by the secret service and the case went away..he was so brazen ,he kills big donnie in the club on 13th. not worried about bugs in the club or maybe agents outside..his guys dealt drugs all over..he could be the worst guy in the history of the american mafia.ill think who could possibly be worse..any idea's out there?
