The article presents information on the trail of Jack Ruby, who killed Lee Harvey Oswald, the accused assassin of former U.S. President John F. Kennedy. For five weary weeks the nation's attention had been focused on the Dallas, Texas courtroom, where the trial was taking place, in the hope, however illogical, that a glimpse into the mind of Ruby, who had performed one irrational act, might provide a faint glimpse into the mind of his victim Oswald, who had performed another. But the trial fizzled. The defense did not show Ruby's mind, they showed only a literal recording of his brain waves. There was no psychiatric testimony that went much deeper than the pity-the-poor-boy-who-never-had-anybody-to-love-him level.
