Two things struck me. One, in order for Oswald to hit Kennedy, he would have to lean out of the window , bend to the left and hold steady. Two, if someone wanted to escape the area where it looks like the shots were fired from on the grassy knoll area ,all they had to do was go around a flimsy little picket fence and, Bingo.. nothing but railroad tracks and highways. They could have disappeared into thin air, very quickly. Espicially while everyone was looking in the opposite direction for a moment. It was a eprfect set up. My only question is by whom?
