Are you ok, Mr Graves? Is this the kind of manic behavior that got you banned from the Education Forum?
Now! That particular frame is important simply because it's the only frame after the man's turn in which we get an unobstructed view of his left arm 

I never believed he had his left hand in his pocket while turning, silly! 
Is he holding something in that left hand as he's turning? I don't know, that's what I'm trying to establish...

I think his left hand is in his (left!) pocket in the final frame (on the right here):

You--------------on the other hand--------------think he's holding an umbrella as he turns and is still holding (or "clutching") it by the handle in this final frame. This is clearly because you want him to be the man in Bell, who is carrying something.
But! You haven't explained the fact that we don't see any of his hand in this final frame:

Is this because you don't have an explanation?
------------------------ Alan,
----------------------------------- No, it was the machinations which Michael Clark perpetrated on me and an unwitting Kathy Beckett that got me banned from James "Jumbo Duh" DiEugenio'd
de fecto (sic) forum.
As far as your slightly paranoiac nature and tendency to assume too much is concerned, I believe it's possible that
both of those tan-jacket-wearing guys were carrying umbrellas that day, don't you?
And let me remind you that it was a highly respected JFK researcher at the EF who posited that the dude in the parking lot was grasping the curved, dark-colored handle of an umbrella in his left hand, not I.
Didn't you notice that when you read that EF thread for the first time in your life a couple of days ago?
