Example of "fact checking website", (won the pulitzer… sik) actually forging fakes :
https://www.politifact.com/facebook-fact-checks/statements/2019/apr/16/viral-image/photo-muslims-laughing-front-notre-dame-doctored/
here article from sputnik defending itself, with original photo : https://fr.sputniknews.com/france/201904191040809188-notre-dame-photo-virale-sputnik/
Checked the photo, as long experience graphist and photographer, what's wrong with… wait oh i see, university of Denver….
>But the National Center for Media Forensics at University Colorado Denver pointed us to this version of the image, which appeared online before the Sputnik story. Analyzing that image, the center’s researchers were able to see that the men were inconsistent with the rest of the photograph.
IMO, the inconsistency here resides only into their brains…
