Mr. O'Donnell. I would not know.
Mr. Specter. Do you know what the President's practice was as to whether or not the seat would be raised?
Mr. O'Donnell. I don't know that, either.
Mr. Specter. Do you know what the controls were on the Presidential automobile for raising or lowering the President's seat?
Mr. O'Donnell. No; I don't.
Mr. Specter. How many shots were there in all?
Mr. O'Donnell. Three.
Mr. Specter. What is your best estimate as to the total time which elapsed from the first shot to the last shot?
Mr. O'Donnell. I would say 5 to 6 seconds.
Mr. Specter. And was there any distinguishable tempo to the shots?
