The Chairman. Between it and the Vice President's car?
Mr. Jackson. Yes, sir; that is right.
Mr. Specter. Wasn't there a Secret Service car immediately behind the Vice President's car, if you know?
Mr. Jackson. There must have been. That is what I can't recall is which was which in there. I knew the White House press was in there but I didn't know how many cars. I am sure there were Secret Service cars, yes, sir.
Mr. Specter. As you were proceeding along in the motorcade, were you within sight of the President's automobile?
Mr. Jackson. At times. When he was—when we could not get a clear view of it because of the photographers in the car ahead of us who were sitting up on the back of the seat just like we were, we did not have a clear view of the car at all times.
Mr. Specter. As you proceeded along approximately how far behind the President's car were you, expressed either in cars, block lengths or in any way that is convenient for you?
Mr. Jackson. Well, I would say approximately a block, average city block, maybe closer at times.
Mr. Specter. Mr. Jackson, I show you a photograph which has been marked heretofore as Commission Exhibit No. 347, and ask you to look at it for a moment, and see if you can identify what that photograph depicts.
Mr. Jackson. Yes, sir; this is the scene of the assassination, parade route, Main and Houston, left on Elm.
