Uh oh... I don't think you were supposed to see this... Who is this fellow?

[Jake Maxwell]

Maybe this fellow is on a walkie talkie...

He's in the foreground of Zapruder's film... next to the bench... and likely on a walkie talkie if you examine closely... not invisible... we can see him...
And no, Mrs. Hester is there to scratch his back...

[Jake Maxwell]

This fellow shows up in 3-4 frames hiding behind the bench.
It is very likely the Hesters were present to provide "cover" for nefarious operatives in the Pergola...

[Jake Maxwell]

With enhancements to help the view...

[Steve Barber]

Jake Maxwell...You are one desperate character.   

 I've never seen anything so stupid in my life as these things you come up with-but this one takes the cake.

So this "fellow" is behind the park bench, therefore behind Bea Hester, and in full view of her husband, and Abe Zapruder and Marilyn Sitzman. 

 You should be banned from this forum for spamming it with these absurd threads you start.  But then, on 2nd thought, perhaps Duncan is allowing a bit of
 humor in this place.  You draw these little comical faces over incredibly blurry images, and insult the intelligence of people in here by trying ever so
 desperately to get people to see what you say you see.   You simply can't be taken seriously.
