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. Mr. SPECTER. Now, which street did the Presidential motorcade take coming on to that scene which you have described as the assassination scene. Mr. JACKSON. They were on Houston. Mr. SPECTER. And before Houston what street were they on? Mr. JACKSON. Main Street. Mr. SPECTER. What direction were they proceeding on Main Street? Mr. JACKSON. West. Mr. SPECTER. Now without reference to the photograph, will you tell us what happened as the motorcade proceeded west on Main Street? Mr. JACKSON. Well, on Main, as we neared Houston Street everyone was more or less in a relaxed state in our car, because we were near the end of the route, I guess, nothing unusual happened on Main Street. The final block on Main, before we turned on Houston I was in the process of unloading a camera and I was to toss it out of the car as we turned right on Houston Street to one of our reporters. Mr. SPECTER. Had that been set up by prearrangement? Mr. JACKSON. Yes, sir. And that I did as we turned the corner, and when--it was in an interval and as I threw it out the wind blew it, caught it and blew it out into the street and our reporter chased it out into the street and the photographers in our car, one of the photographers, was a TV cameraman whom I do not recall his name, and he was joking about the film being thrown out and he was shooting my picture of throwing the film out. Mr. SPECTER. At this point could you tell us, to the best of your recollection, precisely who was with you in the car at that time? Mr. JACKSON. Jim Underwood from KRLD-TV station, Tom Dillard, chief photographer for the Dallas Morning News, and me, and then two newsreel cameramen who I know by sight but I don't know their names.
