The issue in the Rittenhouse case was about zooming in on and enhancing a tiny region in a video frame claimed to show Rittenhouse aiming his rifle at protesters[0]. The pixels intepreted as Rittenhouse's support hand turned out to already be present in the frames before he approaches[1], so it's hard to argue that the judge's decision (show the unmodified video, or get an expert to testify about Apple's upscaling) wasn't correct. That there were in fact misleading pixels/artifacts, and that they were from traditional non-AI photography/upscaling, makes this example cut against the article in both ways.
For cases like the rally, where we have multiple independent perspectives, I also don't think much changes. The hard part would be the conspiracy between many participants including major news organisations. Photobashing a crowd, or "An actual, non-AI-generated cockroach in your takeout", in one person's image has never really been difficult.
