Where did Zapruder say the he didn't recall stopping and re-starting the film?
Newsweek never had the film. The original (and a first generation copy) was owned/purchased by Time/Life magazine.
Where did you get this information that over a hundred frames were damaged? And where is your information as to which frames were damaged?
From what I've read, Time/Life said the ORIGINAL was damaged (a few frames but not over a hundred). So they took the frames from the first generation copy they had and added or spliced them to the original. Nothing was removed or taken out.
Zapruder's Shaw testimony is here: http://www.jfk-online.com/zaprudershaw.html
ZAPRUDER/SHAW TESTIMONY
ATTORNEY - "Is the copy you have here today Identical to the original or are there any plates missing?"
ZAPRUDER - "That would be hard for me to tell, Sir."
COURT - "I cannot hear the witness. What is it?"
ZAPRUDER - "That would be hard for me to say. He asked me if there were any frames missing."
COURT - "What is your answer?"
ZAPRUDER - " I couldn't say."
Clearly, Zapruder while under oath is Not going to verify that the Zapruder Film he himself brought to court has Not been altered.
