Look at the shape of their heads. The street Derek has a rectangle face. The mugshot Derek is of a man who has a rounded head.
Their faces are also different
Same guy. Don’t even try some stupid conspiracy theory.
The street cop’s face looks rectangular because of the shadow from his sunglasses. The mugshot’s head looks round because the image is compressed.
Their faces are the same except for shadows and expression.
The ears are different.
the perspective of the face may be changed by the size of the jpeg... distorted, but his ear is the same and it is the same guy... a murderous cop, drunk with power.
