“What we have here is two nuns in coats. That is all.”
You are wrong. Look at the vehicle behind the nuns in both pictures. Different vehicles.
What you have is a nun who is walking many steps with her hand in one position. Keeping the coat closed but not zipped up.
She is hiding something.
Could be something innocent.
But she is hiding something. I can see it in those photos. You can see it better in the lightened photos.
Seriously, you need to step back and breathe. The photos were taken at different times, maybe 30 seconds, a minute, or more apart. It is pretty obvious they were walking so the surroundings would be different as their position changed as they walked. Like I said, you are obsessing over irrelevant details. This is exactly why lib trolls love to push conspiracy theories on sites like this, it gets us distracted and chasing invisible rabbits down holes so we not only look like idiots, but we are distracted and spend our time away from the bigger issues.
OK addressing the different vehicles in each picture- photographers take a bazillion pictures, so in this case we have one picture taken with the first car in the background, then as they walk some more another picture is taken and it has the second car in the background.
What we have left is the “bulging” jacket of the nun on the left.
Question: what is she holding in her left hand?
A more likely scenario than the nun being a disguised hitman dressed as a nun who hangs around the crime scene to watch would be that she is holding her arm over her pregnant belly.
