This chapter analyzes which party of the conflict was involved in the Maidan massacre in Ukraine on February 20, 2014. Testimonies by the absolute majority of wounded Maidan protesters and nearly 100 prosecution and defense witnesses at the Maidan massacre trial and investigation in Ukraine, testimonies by several hundred witnesses, synchronized videos, and medical and ballistic examinations by Ukrainian government experts confessions by 14 self-admitted members of Maidan sniper groups, bullet hole locations show that both the police and protesters were massacred by Maidan snipers located in Maidan-controlled buildings and areas. Content analysis of synchronized videos revealed that the specific time and direction of shooting by Berkut policemen, who were charged with the massacre, did not coincide with the killing of specific protesters. The Maidan massacre trial verdict confirmed that many protesters and policemen were killed and wounded on February 20 from Maidan-controlled buildings and areas and that there is no evidence of the massacre order by the Yanukovych government or Russian involvement. Because of the cover-up, no one is serving prison sentences for this massacre. The false-flag massacre was organized and carried out with the involvement of oligarchic and far-right elements of the Maidan opposition to overthrow the incumbent government in Ukraine.
