Carolyn Arnold basically has 3 Different stories
The Nov 26 1963 FBI statement which she did NOT sign, (my mistake earlier) which has NO mention of a 2nd floor lunchroom sighting of Oswald. This is the the statement of a 12:15 “glimpse” of Oswald in the front foyer of 1st floor between the front doors and the 2nd set of double doors to the warehouse
Then the March 18 1964 FBI statement which she DiD sign, Carolyn Arnold has NO mention of any sighting of Oswald WHAT SO Ever. There is Nothing at all about a 2nd floor lunchroom sighting. She changes time of exiting the TSBD from 12:15 to 12:25.
It’s not until 1978 when Carolyn
Arnold’s no.3 story of 2nd floor sighting of Oswald is told in interviews with Earl Golz and Anthony Summers.
And it was then that she denies the Nov 26/63 statement is true.
IDK what to think now, but I doubt seriously that the FBI would falsely make a statement that would give Oswald an alibi, such as having witness observing him in the front foyer entrance at 12:15
More probably, IMO, the FBI would be compelled by the Hoover memo to “convince” Carolyn Arnold that she must have seen Lovelady instead of Oswald and that a statement of NOT seeing Oswald at the time of shooting would be helpful. And to sign that statement.
Hence the follow up March 18 1964 Signed FBI statement by Carolyn Arnold declaring not seeing Oswald at time of shooting and no statement of lunchroom or any other sighting of Oswald.
