The issue here is that with the ukrainian side taking the “there was no gunshots from any maidan protester buildings” position it eliminates all trust. Folks in crimea don’t trust anything they say they’ll do now or in future because they see them as lying about core narratives that led up to this situation. Meanwhile you have research papers in american universities saying things like:

This academic investigation concludes that the massacre was a false flag operation, which was rationally planned and carried out with a goal of the overthrow of the government and seizure of power. It found various evidence of the involvement of an alliance of the far right organizations, specifically the Right Sector and Svoboda, and oligarchic parties, such as Fatherland. Concealed shooters and spotters were located in at least 20 Maidan-controlled buildings or areas. The various evidence that the protesters were killed from these locations include some 70 testimonies, primarily by Maidan protesters, several videos of “snipers” targeting protesters from these buildings, comparisons of positions of the specific protesters at the time of their killing and their entry wounds, and bullet impact signs. The study uncovered various videos and photos of armed Maidan “snipers” and spotters in many of these buildings.
