Mr. Eisenberg. How difficult is it to give this—a lead of this size—to this type of target?
Mr. Frazier. It would not be difficult at all with a telescopic sight, because your target is enlarged four times, and you can estimate very quickly in a telescopic sight, inches or feet or lead of any desired amount.
Mr. Eisenberg. Would it be substantially easier than it would be with an open or peep sight?
Mr. Frazier. Yes. It would be much more difficult to do with the open iron sights, the notched rear sight and the blade front sight, which is on Exhibit 139.
Mr. Eisenberg. Now, you have been able to calculate the precise amount of lead which should be given, because you have been given figures. If you had been in the assassin's position, and were attempting to give a correct lead, what lead do you think you would have estimated as being the necessary lead?
Mr. Frazier. It would have been a very small amount, in the neighborhood of a 3-inch lead.
Mr. Eisenberg. As opposed to the 6 or 8 inches?
Mr. Frazier. As opposed to about 6 inches, yes.
Mr. Eisenberg. What would the consequence of the mistake in assumption as to lead be—that is, if you gave a 3-inch lead rather than the correct lead?
Mr. Frazier. It would be a difference of a 3-inch variation in the point of impact on the target.
