А по ссылочкам на этом сайте ходить не пробовали? 9.2.7 The three shots were made in under six seconds.
Since Connally reacted to the Magic Bullet eight-tenths of a second af-
ter JFK (so far as they could see in the Z-film), the WC determined two
possible times for the shot. They said the unambiguous head shot there-
fore occurred from 4.8 to 5.6 seconds later. This is where the six-sec-
ond figure comes from. They also said another shot missed, but they
weren't sure whether it came first, second, or third in the sequence.
They argued the merits of all three scenarios. If the second shot was the
miss, the 4.8 to 5.6 seconds would be the overall time for all three
shots. If the first or third shot was the miss, the minimum time to reload
the rifle (2.3 seconds) had to be added to the overall time, giving a min-
imum time for all three shots of from 7.1 to 7.9 seconds. Much study
has now determined the first shot to be the miss. Furthermore, the am-
biguity about the time of the Magic Bullet has been resolved. At about
the time JFK reacts to the shot, the lapel of Connally's suit coat flips
forward. Dr. Lattimer has proven experimentally that this could only
have been caused by a tumbling bullet. Thus, 5.6 seconds becomes the
differential between the Magic Bullet and the head shot, with the over-
all minimum for the three shots established at about eight seconds.
