And what many overlook is the 6.5 seconds commenced at the sound of the first shot, so Oswald in effect had roughly 6 seconds to fire the remaining two shots. - ScottinVA
Agreed. PLUS, modern analysis of the Zapruder film, trying to match the frame rate to actual time elapsed, suggested that 8.3 seconds elapsed between the first shot and the last shot, rather than 6.5 seconds.
And that 8.3 seconds STARTS with the first shot, so 8.3 seconds is a long time to fire two shots. Particularly when Oswald was probably familiar with his own rifle, and when sporting goods dealers, sportsmen, and others completely unfamiliar with that make of rifle were able to fire three shots, and hit targets, in 4-6 seconds in the U.S. Army and CBS tests.
Which most likely he was, considering he'd tried it out on retired Maj. Gen. Edwin Walker that previous April. Conspiracy types are having trouble accepting that Oswald was a bad individual with evil in his heart.
