This is the famous picture taken by Associated Press photographer
James Altgens, snapped between gunshots #2 and #3. Both of the
limo's victims (JFK and Governor John Connally) can be seen through
the car's windshield reacting to their wounds, which were sustained
just seconds earlier when bullet "CE399" from Lee Harvey Oswald's
rifle pierced the backs of both men.
