After seeing the re-enactment by the sniper/ballistics expert who tried to get off the 3 shots in the amount of time that Oswald did, and with the same accuracy, he concluded that it was virtually impossible, and it was certainly convincing.
Not sure which re-enactment you are referring to,but there have been several attempts to re-create Oswald's feat. An FBI agent,a television special on Discovery,a few independent investigators,and others have all shown that not only was it possible,but it was actually probable.The discrepancy seems to lie in an initial estimate of the alloted time based on the frame rate of the Zapruder film. The error is in assuming the timing of the missed shot. No one knows if Oswald missed with the first shot,or the third shot.What is undisputed,based on the video,is that the two shots which we see strike Kennedy could easily have been fired in the time shown on the Zapruder film. The other shot is irrelevant because Oswald could have missed with his first shot or could have fired a third shot after the head shot,and missed with that one.
Since no one knows when the third bullet was fired,there is no way to speculate on the timing of anything other than the two undisputed shots that we see.
