I’ve ruled out that PM is the women reporter with a microphone, because its highly doubtful she would have not informed anyone about being on those steps and witnessing the event from that vantage point.
Pauline Sanders is a good fit imo, but as Mr.I and myself have pointed out, her known recorded statements have no mention of moving from her east side of the entrance steps to the west side.
The object in the hands of PM is not likely a camera being raised to take a photo because surely there would have been a photo from such camera contributed to the investigators.
What then is it? It’s not a white sandwich because why would there be only one bite taken and then never again?
A woman’s make up thingy or mirror being raised to check one’s appearance? Now why would a woman who’s basically back in the shadows who isn’t likely going be seen anyway ( and is only a 5’2” woman wearing glasses like Sanders) be worried about her appearance?
Not likely a cigarette lighter as there’s no indication of erratic change/flicker in the shape of the white area nor does there appear to be cigarette in PMs mouth.
A white radio? It would have been held up to the EAR at the SIDE of the head, not up to the mouth.
Since it does appear it’s going up to the mouth and down again in just a few seconds then it’s more probably a bottle with white label or it’s a white cup, with liquid in it, because there’s not much reason to lift up an EMPTY bottle or cup to mouth.
Since it’s therefore promote probably a bootie or white cup, then which one is more probable?
If PM is Pauline Sanders, she could have brought out a white cup of some liquid. However as Walt Cakebread once suggested, would such a small cup if having coffee or tea in it not have already been totally consumed in 15-20 minutes waiting on the steps?
So this points to a larger bottle which contains 20 0z or larger volume of liquid which if such bottle had been bought at 12:17 from the 2nd floor lunchroom, has a fair probability that some % of liquid was still left in the bottle at 12:29.
Now all one has to do is prove that a bottle of a 1963 Dr.Pepper bottle (or Coke) from the 2nd floor lunchroom soda machine has an oval shaped white label that could plausibly appear as a white fuzzy ball if held in hand by someone standing in the shadows at PMs location at 12:29 Nov 22/63, with label facing towards the camera, and the bottle held by the hand at the base of the bottle thus not obscuring the label.
