The autopsy of Kennedy shows small wound in the back of head, top and side blown off, and no wound in the front. The bullet fragments were in his head, which makes a forward shot impossible. The video is deceptive because it is from behind and doesn't see full explosion.
Oswald was a good shot, he was rated sharpshooter and marksman in the Marines. Lots of people left to watch the motorcade. Memories are always unreliable. Oswald was supposed to be working.
It is possible that FBI was working from bad info or incompetent. It was thought that the last two shots were rapid fire. But there is better info now that the shots were spaced out with plenty of time for bolt action rifle, and the "rapid fire" was echos. Lots of people have recreated the shots, some not that good shots.
