Anyone can look at the newly released file and see that Hoover's testimony was altered to remove his reference to a large wound in the back of the head. The file shows the word “portions” was penciled in before “of the skull,” while the typewritten words “the back” were crossed out. His original statement was that
. . . the back of the skull had been practically shot off.
This was changed to
. . . portions of the skull had been practically shot off.
This is certainly a substantive change. As many here know, over 40 witnesses, in three different locations, said there was a large wound in the right-rear part of JFK's head. These witnesses include two of the morticians who reassembled the skull after the autopsy, nearly all of the Dallas doctors and nurses (including the two nurses who cleaned the skull and wrapped the head in a sheet), and numerous witnesses at the autopsy.
Hoover almost certainly got his information from Sibert and O'Neill, both of whom said there was a large wound in the right-rear area of the skull.
