 And it was not a question, but a statement. Wanting to be certain, Bobby sent that same Walter Sheridan to Dallas to find out if the mafia had planned the crime. They had not. Bobby also asked a mafia-connected Chicago lawyer, Julius Drasnin, who worked for the NLRB, the same question. The answer, as Drasnin reported to Walter Sheridan, was that the assassination was not a mafia hit. Years later, Sheridan would testify under oath that the mafia was behind the assassination. He knew better.
