There were so many errors in your post, I don't know where to start. So I will respond only to item #3) second and third shot were very close together. Are you "Oswald Framers" so blind that you don't see what this means? It takes time to operate the bolt of the "humanitarian rifle." YOU CAN'T HAVE A SINGLE ASSASSIN AND TWO SHOTS VERY CLOSE TOGETHER, RIGHT? This could be done with an automatic rifle, but not a bolt action rifle. If you have two shots close together, you have two assassins. But again, this is only one of a startling number of reasons why the magic bullet is a scientific impossibility.
If the second shot was just before JFK's hair flies up, which was seen to occur by Hickey on the second shot, (which is just before Greer turns around for the first time, which he said he did immediately after the second shot) then the second shot was about z271-272. That fits the shot pattern: 1 ..........(4 seconds).........2..(2.3 seconds)..3
2.3 seconds between 2 and 3, is enough time for Oswald to fire all the shots.
