I too believe that it was a Mob hit,approved by Gambino and Genovese Families. From what I heard,a lot of the local merchants and League supporters were informed that their presence at the rally would not be necessary. I believe that the reason they picked Mr. Johnson was pretty simple. They wanted a hitman that would never be connected to the Mob. After all. the agenda of organized crime is to downplay the Mafia's existence. So who better than a member of an ethnic group that would never be in the Mob. Could have just as easily been an Asian or an Indian.
