Mr. Jackson. I would say to me it seemed like 3 or 4 seconds between the first and the second, and between the second and third, well, I guess 2 seconds, they were very close together. It could have been more time between the first and second. I really can't be sure.
Mr. Specter. Are you sure you heard three shots?
Mr. Jackson. Yes, sir.
Mr. Specter. Now, will you mark on the overhead shot, which is Exhibit 347, with a "Y" as precisely as you can the position of your automobile at the time you heard the second shot?
Mr. Jackson. With a "Y"?
(Witness marking.)
Mr. Specter. Would you now mark on the same exhibit the precise position of your car as closely as you can recollect it when you heard the third shot with a letter "Z"?
(Witness marking.)
Mr. Specter. When, in relation to the timing of the shots, which you have described, did you first look toward the Texas School Book Depository Building?
