"Hello, Carmen," said Frankie Carbo, boxing's top hoodlum. "Hi, Frankie," said Carmen Basilio (left), the former welter and middleweight champion of the world. Then the two shook hands outside a Los Angeles courtroom. What made this normally unremarkable exchange a remarkable one last week was that inside the courtroom Carbo, currently serving a jail term, stood accused, in effect, of taking over boxing for the underworld, while Basilio was a prosecution witness testifying against him. Although the handshake appeared a set-up—Frankie abruptly shoved through a crowd to wring Carmen's hand—Basilio said tolerantly: "I know who he is, so I shook hands with him. I'd shake his hand again. God forgives everybody. Who am I not to forgive?"
