Mr. BELIN. Well, here is Exhibit 482. First of all, I see a box on Exhibit 482, right in the window. Mr. BRENNAN. Yes; I don't recall that box. Mr. BELIN. Do you recall that it definitely was not there, or just you don't recall whether it was or was not there. Mr. BRENNAN. I do not recall that being there. So, therefore, I could not say it definitely wasn't there. Mr. BELIN. You cannot say whether it was or was not? Mr. BRENNAN. No. Mr. BELIN. On Exhibit 482, do you want to point an arrow to where you believe you can see boxes back there. Or where you saw boxes. All right. Let the record show that Exhibits 480, 481, and 482 were taken by, I believe it is, Underwood or--just a second. Thomas C. Dillard, Chief Photographer of the Dallas Morning News, who was riding in the car with Robert H. Jackson, who has already testified before the Commission, and the deposition of Mr. Dillard will be taken by Mr. Ball and me in Dallas in the first part of April. And that Exhibits 480, 481, and 482 were taken shortly after the firing of the third shot. I think that this should appear in the record. I think it should also appear in the record that Exhibit 479 is one of the frames from the Abraham Zapruder movie film. Mr. Brennan, from the time you first saw the Presidential motorcade turning north on Houston from Main, did you observe the window from which you say you saw the last shot fired at any time prior to the time you saw the rifle in the window? Mr. BRENNAN. Yes. Mr. BELIN. Well, what I am saying is this. You saw the motorcade turn? Mr. BRENNAN. No; not after I saw the motorcade, I did not observe a man or rifle in the window. Mr. BELIN. Did you observe the window at all until after you heard that first sound which was a backfire or firecracker, at least you thought it was? Mr. BRENNAN. No. Mr. BELIN. So you did not observe the window and would not know whether or not there was any man in the window during that period? Mr. BRENNAN. No. Mr. BELIN. Well, let the record be clear. The first sound you first thought was what? Mr. BRENNAN. Backfire of a motorcycle. Mr. BELIN. And then you later said something about a firecracker. Did that have reference to the first shot, or something in between the first and last? Mr. BRENNAN. I positively thought that the first shot was a backfire of a motorcycle. And then something made me think that someone was throwing firecrackers from the Texas Book Store, and a possibility it was the second shot. But I glanced up or looked up and I saw this man taking aim for his last shot. The first shot and last shot is my only positive recollection of two shots. Mr. McCLOY. Did you see the rifle explode? Did you see the flash of what was either the second or the third shot? Mr. BRENNAN. No. Mr. McCLOY. Could you see that he had discharged the rifle?
