1) Are you a shooter, who has processed game he has shot before?
2) Have you been to the 6th floor of the TSBD and seen the site?
Have you actually stood in the window? Those many if not all the “documentaries” are shown from a different window because they blocked the correct window off from being disturbed shortly after the museum’s opening. I’ve stood in the correct window and the best shot would have been while the car was coming down Houston, not after the turn onto Elm. Oswald would have had to have crawled out onto the window ledge to get an aim and a miss would have hit Nellie Connally or Greer, the driver. That corner onto Elm is weird as it has a curve and a small hill so the target was moving two directions and out of range of the window. On S. Houston street, the car would have been travelling straight toward Oswald and on level ground. So, why didn’t Oswald take the easier shot?
A shooter from the grassy knoll or the railroad tracks would have taken the Elm St. shot but not the Houston shot.
