Let's consider the issue of whether Oswald looked pale. We heard the reporter Tom Petit say that Oswald looked very pale when they brought him out from the P.D.
I'm not detecting any paleness, myself. Compared to the others, the greyscale of his coloring in the black and white issue is comparable to theirs and not particularly pale. But, let's look at him at Parkland.
Well, he doesn't particularly pale to me there either. His skin tone is comparable to the others. Yet, I cannot doubt that he has been shot at this point because they are at the hospital, and they certainly didn't shoot him after this. So, this remains an enigma why his paleness isn't evident.
