Je suis frappé par le témoignage de Altgens devant la commission Warren et surtout de l’absence de question de la WC à propos des deux policiers l’ayant éloigné de la zone des voies de chemin de fer.
Cela semble cohérent avec le témoignage d’Hoffman et de plusieurs personnes qui ont été éloignées de cette zone.

Il serait intéressant d’en faire la liste et d’identifiant les éléments semblables et dissemblables.

Mr. ALTGENS - I arrived on the triple overpass at approximately 11:15 a.m.
Mr. LIEBELER - When you say the triple overpass, you mean the railroad tracks that cross over Elm, Commerce, and Main Streets ?
Mr. ALTGENS
– Yes, sir.

Mr. LIEBELER
– As they run near the Texas School Book Depository Building ?

Mr. ALTGENS
– As well as in the opposite direction.

Mr. LIEBELER
– Yes, sir.

Mr. ALTGENS
– My original assignment was to make a pictorial scene of the caravan with the Dallas skyline in the background and the triple overpass was selected as the site for making that picture, and when I arrived on the triple overpass there was no one up there but two uniformed policemen and one of the uniformed policemen came over to me and asked me if I was a railroad employee and I told him, "No," and I showed him my press tag and told him I had a Department of Public Safety ID card showing I was connected with the AP—Associated Press, and he said, "Well, I’m sorry, but this is private property. It belongs to the railroad and only railroad employees are permitted on this property." And, I explained to him that this was a public event and I thought I would be privileged to make a picture from that area, and he says, "No. This is private property and no one but railroad personnel are permitted in this area."
This is a little extraneous but I wanted to point this out, and I said, "Well, it looks like you have got it pretty well protected from this area because I see you two uniformed policemen on this overpass and I see you have another uniformed policeman on the overpass on Stemmons," and he said, "Yes, and no one is permitted over on that overpass." So, then, I had to decide on another location for shooting my pictures, so I proceeded on across the triple overpass into the parking lot which is just behind the Book Depository Building and proceeded on down to Elm to the corner of Elm and Houston, crossed Elm going—is that east or south—I guess it is south on Houston. Yes ; south on Houston over to Main and Houston. That seemed to me to be the most likely spot to make any pictures. Then I could, by advance planning, get away from that spot after I had made a picture or two and run across the Dealey Plaza and catch the caravan again down on Elm as it proceeded toward the triple overpass and probably get some more pictures, and that was my planning.
Well, I was at that site when the Presidential caravan arrived at that intersection.

Mr. LIEBELER
– That intersection being the intersection of Houston and Elm Streets ?

Mr. ALTGENS
– Houston and Main.

Mr. LIEBELER
– Houston and Main ?

Mr. ALTGENS
– Yes ; Houston and Main.
