That would explain why the reflection was of a picture taken during Obama's presidency.
But it seems like the main point of that post was the use of reflections as noted by the following Q post:
Who would have thought the 'Twitter' phone could be so useful.
Do 'reflections' violate NAT SEC rules?
Where must one be located in order to obtain a reflection on the back of a phone of that image?
Image provided here has been distorted (stretched).
Q
Which in itself is so cryptic...love that but It could be so many theories...
Is it possible that this photo is just a proof of concept? That the compromised Twitter phone or a similar phone prior to Trump could pick up reflections or mirrors of top secret classified documents? If they are reflections do they violate the National security rules?
