Are you sure that Lee was being charged as an accomplice ??..... You may be right...but I'm pretty sure that on 11-23-63 Hoover said that the white house needed to release a statement that stated that Lee Harvey Oswald was simply a lone nut killer who had no accomplices.
We need to distinguish between
a) what the press was being told
b) what Mr Oswald was being told
c) what Mr Oswald was being told the press was being told
"I don't know what dispatches you people have been getting............"
