Regardless of fakeness, misleadingness, or realness, is the the dunkee referring to an actual photo album, or is he just aggressively squeezing the faith out of his mustard seeds on this one?
As far as I can tell, he is just kind of guessing based on cultural osmosis. There is no photo of tank man being crushed, and I don't think even photos people claim are him being crushed. People just allude to "evidence" that they have never even looked up, let alone looked at, let alone verified.
Tank Man himself was videoed leaving the scene without being squished by tanks (there's something slapstick about how the tank keeps trying to go around and he keeps moving) but there is an album floating around on imgur and such with a bunch of gore photos. This is probably what he's talking about:
Probably NSFL
Here's one small iteration of the album. I've never seen it accompanied by provenance, and the photos are scattered enough that I don't feel confident drawing any conclusions without expert interpretation. Pic 14 is a good example. Without priming your mind via caption, what is even depicted here? How can we tell where or when it was taken? The Tank Man video (and some of the photos with bodies lying in the square) you can at least clearly place the location.
Like GalaxyBrain says, it's also possible to look at some of these photos and say "these are actually dead Chinese LEO/military" or whatever. Idk about that one way or another except where we can clearly see uniforms.
