Are you arguing that because there are hypothetically a million mobilizable supporters of Trump that the image doesn’t clearly contain deep fake crowd size expansion? Refer to the image. It is as clear as day.
In this case there is clear evidence that tampering of images and video of the event has taken place. If you look at the video and many of the still images from Getty of Jan. 6th you can clearly see content-aware crowd filling alteration. This evidence does not in any way necessarily imply the existence of a grand conspiracy, nor am I making any claim supporting anything of that nature.
