Friends!
There is an extremely important piece of information given by the Wiegman film that remains much ignored in commentary on the issue. Look closely at Prayer Man's hands:
They are holding two different things. How do we know this? Because when his right hand is brought up to his mouth (earlier frames)
his left hand stays where it was---at upper chest level.
I can think of only one realistic scenario that explains what we're seeing here:
--------------Left hand: a drink
--------------Right hand: a piece of food
In my opinion-------we are seeing, in the right hand, the eaten (= white) side of an apple.
Mr Oswald told Captain Fritz he brought
cheese sandwiches and an apple to work that day.
Here's something else he told Fritz:

So! Mr Oswald
-------------Buys coke in 2nd fl lunchroom
-------------Brings coke downstairs to domino room, where eats sandwiches
-------------Brings half-finished coke, and the apple, out front to watch parade.
By the time of Darnell, the apple is all eaten and the (empty?) coke bottle placed down on the ground. Mr Oswald's arms are now folded.
