Everyone can see that BHO has been retroactively inserted into the exact photograph shown in post #109.
The moment in time of the facial expressions of the Dunhams is identical in both pictures.
In #109 the vertical line of mortar to the right of the granny is in the exact same spot as shown in this photo even though another body has been inserted in between the old couple. This indicates she did not move to make room for him to sit there.
It's tricky. If the Dunham couple were sitting next to each other, and were moved apart by manipulation of the image to accommodate zero, both sides of the wall and mortar would stay the same. Just as they remain the same when zero is removed...
A better indication might be the position of the bench supports and the position of the three people in relation to the bench. Does it seem there's enough room there for three people? Have the uprights of the bench been moved?
There's no doubt the actual location of the bench has been found and photographed. The small dip in the top of the wall confirms it. It's all far from conclusive imo.
What interests me is that Stanley Ann Dunham obviously visited him in New York, and might have been the one who took the photographs. That's the Boener guy who maintains he shared an apartment with zero, standing in the group with zero and Stanley Ann. Zero appears to be wearing the same blue shirt he is shown wearing under the leather jacket on the bench, and sitting on the bridge. One has to look at all the images from that episode to attempt to get some context.
I don't recall seeing any photographs of the elder Dunhams and zero after he graduated from Panahou. This appears to be the only one, and if it's a manipulation, is has to because it serves a purpose.
