Abraham "Crocodile-Tears" Zapruder... on a walkie-talkie!

[Royell Storing]

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...
 

      Zapruder was wearing a suit with dress slacks, so I do not believe this is him. This individual looks to be wearing a heavy coat or duster of some kind. I do Not see a rifle. All of that said, this image is a very good find.

Fella, you need to get your eyes checked if you think that still frame shows "someone" "holding a rifle" ...

  I can Not say I see a rifle, but this is still a very good find.

Those who are familiar with rifles will most likely recognize what is called a high "low" ready position...

[Tommy Shanks]

Uh huh. And this person with a rifle standing in a "firing" position was somehow not seen or noticed by anybody else in Dealey Plaza? Your  magical powers of photo interpretation never cease to amaze!

   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.

The worst elements of law enforcement were in the game...
Only Oswald needed to be fearful, since he was the pre-selected fall guy...
Everyone else on site for nefarious reasons were likely instructed to claim they were Secret Service on security detail... so having a rifle in sight of everyone was not a problem if you were given a badge to wear or had uniformed law enforcement nearby as cover...
This is likely a shooter in the high "low" ready position, perhaps using his rifle scope to view the damage...
