Yeah that does look odd, but it could be just a slight error in the way the visual image was coded into digital data by the camera. Digital cameras don’t actually record a physical image of the picture in the way old chemical film cameras captured a physical image on film. Digital cameras read the visible light at one instant in time and convert the visible light into a digital code using a complex algorithm and processing by semiconductors. That digital code then gets saved as a picture file on the camera, and is transferred over to a computer, where it now can be decoded and view on any computer.
There may have been just a slight error in the way the visible light was converted into digital code by an algorithm in the camera, and that’s why the frame of the sunglasses appears to be out of position.
Btw, regarding post #721 there seems to be another anomaly in that same exact area of the suspects head.
Look closely, directly above suspects right ear, at the hair of the man standing behind him. It's the hair, right at the top of the ear area. This area also appears as though it was possibly manipulated.
So there seems to be not one but two anomalies exactly where someone would manipulate the image if they were going to replace the face. Both anomalies are directly around the suspects face and in the same area. I did not see any others in the image. Could these anomalies be a fluke or digital artifacts? I dunno, but they sure jumped out at me, given their locations on the image.
