If anyone wants an example of this, look at the coverage of the crowd size at Trump's inauguration. That's still held up as the canonical example of the Trump administration's "alternative facts" (in fact that's when the phrase was coined, I believe). But there's high resolution video of the crowds during the ceremony that clearly contradicts the photos of sparse crowds. I also think the guy is a lying moron, but the fact that that photo is still the cover image for campaigns against him should give people pause...
