The Secret Service has been around since 1865. No agent has ever broken the apolitical rule of the Secret Service until Emory Roberts came along. Roberts was appointment secretary to LBJ while still a member of the Service!
This is covered in the book but I thought you would find this post/ link----with the images attached----fascinating.
Bottom line: what is your take on all the Dealey Plaza, Parkland, and Besthesda witnesses who (seem to) state that the back---the right rear---of JFK's head was missing? Every time I feel confident of this "eyewitnessing", someone comes along and throws somewhat of a monkey wrench into the proceedings (even Jerrol Custer, who i interviewed twice on video [11/22/91 for Livingstone/ "High Treason 2" and with Wiliam Law in March 1998 for his book] seemed to waffle a bit, despite his earlier adamant statements...although that could have been the influence of his friend, the late Tom Wilson)
Gary came out in the pages of the Third Decade journal and lambasted Gerald Posner's book "Case Closed", saying "he has given history a sham of a book" (I believe it was the November 1993 issue or thereabouts). Does he still feel this way?
