Okay... what is your best argument against or explanation of this image in the Bell Film... right next to the perch where Zapruder was supposed to be filming?It looks like someone is holding a rifle...
Fella, you need to get your eyes checked if you think that still frame shows "someone" "holding a rifle" ...
Those who are familiar with rifles will most likely recognize what is called a high "low" ready position...
This figure appears to be moving toward the Pergola Shelter. Where would he have been positioned previously, to NOW be in this position? A possible shooter would Not be in this position only seconds after the Kill Shot. You have a very good find, but you have not found a possible shooter. His physical position at this point in time after the Kill Shot rules that out.
