Mr. JACKSON. Right here approximately. And as we heard the first shot, I believe it was Tom Dillard from Dallas News who made some remark as to that sounding like a firecracker, and it could have been somebody else who said that. But someone else did speak up and make that comment and before he actually finished the sentence we heard the other two shots. Then we realized or we thought that it was gunfire, and then we could not at that point see the President's car. We were still moving slowly, and after the third shot the second two shots seemed much closer together than the first shot, than they were to the first shot. Then after the last shot, I guess all of us were just looking all around and I just looked straight up ahead of me which would have been looking at the School Book Depository and I noticed two Negro men in a window straining to see directly above them, and my eyes followed right on up to the window above them and I saw the rifle or what looked like a rifle approximately half of the weapon, I guess I saw, and just as I looked at it, it was drawn fairly slowly back into the building, and I saw no one in the window with it. I didn't even see a form in the window. Mr. SPECTER. What did you do next? Mr. JACKSON. I said "There is the gun," or it came from that window. I tried to point it out. But by the time the other people looked up, of course, it was gone, and about that time we were beginning to turn the corner. Mr. SPECTER. Which corner were you beginning to turn? Mr. JACKSON. Houston onto Elm. Mr. SPECTER. I now show you a photograph marked as Commission Exhibit No. 348 and ask you if you can identify what that depicts? Mr. JACKSON. This is the School Book Depository. This is the window the two colored men were looking out of. This is the window where the rifle was. Mr. SPECTER. Will you mark the window where the rifle was with an "A" and would you please mark the window where you have identified the men below with a "B." (Witness marking.) Mr. SPECTER. Referring to your mark of "A," the photograph will show that you have marked the window on the sixth floor with the mark being placed on the window on the westerly half of the first double window. Mr. JACKSON. I am sorry. This window here on the very end was the window where the weapon was. I am sorry, I just marked the double--actually this is the rifle window right here. Mr. SPECTER. Will you take the black pencil again and draw an arrow--before you start to mark, hear the rest of the question--as precisely as you can to the exact spot where you saw what you have described as the rifle. (Witness marking.) Mr. SPECTER. Was the window you have just marked as being the spot from which the rifle protruded, open when you looked up? Mr. JACKSON. Yes, sir. Mr. SPECTER. What is your best recollection as to how far open it was at that time? Mr. JACKSON. I would say that it was open like that window there, halfway.
