Mr. Frazier. Yes. I would say from 4.8 to 5 seconds, in that area—4.6 is firing this weapon as fast as the bolt can be operated, I think.
Mr. Eisenberg. I am now going to ask you several hypothetical questions concerning the factors which might have affected the aim of the assassin on November 22d, and I would like you to make the following assumptions in answering these questions: First, that the assassin fired his shots from the window near which the cartridges were found—that is, the easternmost window on the south face of the sixth floor of the School Book Depository Building, which is 60 feet above the ground, and several more feet above the position at which the car was apparently located when the shots were fired.
Second, that the length of the trajectory of the first shot was 175 feet, and that the length of the trajectory of the third shot was 265 feet.
And third, that the elapsed time between the firing of the first and third shots was 5½ seconds.
Based on those assumptions, Mr. Frazier, approximately what lead would the assassin have had to give his target to compensate for its movement—and here I would disregard any possible defect in the scope.
Mr. Frazier. I would say he would have to lead approximately 2 feet under both such situations. The lead would, of course, be dependent upon the direction in which the object was moving, primarily. If it is moving away from you, then, of course, the actual lead of, say, 2 feet which he would have to lead would be interpreted as a considerably less lead in elevation above the target, because the target will move the 2 feet in a direction away from the shooter, and the apparent lead then would be cut to one foot or 12 inches or 8 inches or something of that nature, due to the movement of the individual.
Mr. Eisenberg. Have you made calculations to achieve the figures you gave?
Mr. Frazier. I made the calculations, but I don't have them with me.
Mr. Eisenberg. Could you supply these to us, either in further testimony or by letter, Mr. Frazier?
Mr. Frazier. I have one object here, a diagram which will illustrate that lead, if you would like to use that. This is drawn to scale from those figures which you quoted as building height, and distances of 175 feet and 265 feet.
