The settler-colonial hypothetical is more comparable to this atrocity than the Tiananmen Square massacre. Did you associate this with Tiananmen Square simply because of tanks?
The one where... Tank man blocked a convoy of tanks by standing there?
The one where he was pulled away by his friends afterwards?
It's sort of challenging to hide a crushed body, and yet no journalists who were there the night of or the morning after reported anything. No photographic evidence is available.
You know they pulled those soldiers out and replaced them with soldiers from other regions who would, and did, right? Tiananmen Square is famous because of the massacre they committed after Tank Man.
