Calling all Freeper PixellPeepers... I know that there are forensic image analysis tools that will definitively find evidence of Photoshopping in any image, including jpegs and multi-generational copys. I believe one program is a plugin for Matlab, I think it looks at the statistical distribution of pixels to determine forgery. Perhaps somebody here has actually used it or at least knows what I am talking about.
I just saw 0’s photo op at the Washington Monument on a Sunday talk show and his scar was visible.
