January 6, 1964, was a long day for Martin Luther King Jr. He spent the morning seated in the reserved section of the Supreme Court, listening as lawyers argued New York Times Co. v. Sullivan, a landmark case rising out of King's crusade against segregation in Alabama. The minister was something of an honored guest: Justice Arthur Goldberg quietly sent down a copy of Kings account of the Montgomery bus boycott, "Stride Toward Freedom," asking for an autograph. That night King retired to his room at the Willard Hotel. There FBI bugs reportedly picked up 14 hours of party chatter, the clinking of glasses and the sounds of illicit sex--including King's cries of "I'm f--ing for God" and "I'm not a Negro tonight!"
