Mr. Specter. And what did you see? You have described what you saw in terms of position of his hands.
Mr. Kellerman. That was it.
Mr. Specter. What did you do next?
Mr. Kellerman. That is when I completely turned to my right and grabbed for the mike in the same motion, sideways telling the driver, "Let's get out of here; we are hit."
Mr. Specter. Will you give us the best estimate of the lapse of time from the instant you heard the sound which appeared to you to be a firecracker until you instructed Mr. Greer in the way you have described?
Mr. Kellerman. Seconds.
Mr. Specter. How many seconds?
Mr. Kellerman. Three or four.
Mr. Specter. Now, how long did it take you to relay the instructions which you have told us about to Special Agent Lawson; what your best estimate would be?
Mr. Kellerman. Instant, in seconds again. Again it is three to five.
