The routine so far is that it doesn't matter what the Russian counter-argument is, or what their evidence is, suppression is the real problem on their side of any argument.
Lets say hypothetically that Russia had clear video of blue-armbands throwing 6 gorillion people in a gas chamber, complete with satellite shots, etc, to back it up. The first thing that would happen is search engines and social media blocking it, followed by the Kyiv Independent flipping the script into Russians throwing 6 gorillion people into a gas chamber, their version gets boosted by NATO media, becomes the first version seen by most, while the Russians can only seethe as they're muted and filtered worldwide.
A real example being the woman Azov tortured to death in Mariupol (with the swastika), that the Russians reported week or so ago (
example from March 27), is just now being
re-used with a flipped script where Russians did it. If you try googling about the tortured Mariupol woman now,
you'll just get the newer stories with the new spin.
My point being the information/event itself wouldn't matter if NATO controls the narrative, they have free reign to flip the script, any Ukrainian crime can become a Russian crime instead, any Russian evidence can be repurposed for a new narrative.
