“Then Agnew was replaced with Gerald Ford, not a threat to them.”
Gerald Ford, who had already participated in the Warren Commission cover up. In other words, a known reliable pawn who wouldn’t betray them, because if he did, he’d take himself down along with them.
Tidbit on Gerald Ford:
J. Edgar Hoover had a file on Ford—apparently Gerald like to enjoy the company of prostitutes at the “Kit Kat Club”—and the FBI had the pictures (maybe even video) to prove it.
Ford was totally owned—and in fact there is his actual handwriting in recently released Warren Commission documents where he changed the location of the “magic bullet”.
This is particularly amusing since Ford was not brightest bulb and wouldn’t understand forensics if it ran him over...
