Mr. Jackson. We were sure it came from ahead of us which would be in a northerly direction, northwesterly direction. It did sound as though it came from somewhere around the head of the motorcade.

Mr. Specter. From the second shot, did you have any reaction or impression as to the source of this shot?

Mr. Jackson. No, sir. Through all three shots, I could just tell that it was ahead of me and not behind me, that is it.

Mr. Specter. And the same impression then prevailed through the third shot as well.

Mr. Jackson. Yes, sir. To me it never sounded like it was high or low.

Mr. Specter. Have you had occasion since this incident to relate the factual sequences, your observations and what you heard? Have you had occasion to tell anybody about what you saw and heard as you have described it to us?

Mr. Jackson. Yes, sir.

Mr. Specter. Has there been any variation in your recollection or impressions about your observations on these occasions?

Mr. Jackson. Not to my knowledge. The other times were not as thorough as this.

Mr. Specter. Mr. Chief Justice, those are all of the questions which I have, sir.
