Only days ago, a protester in Oregon, Lavoy Finicum, was gunned down in cold blood. The tyrannical henchmen of the state who executed him will no doubt claim he was reaching for his weapon, so they shot him in order to protect themselves.
Too bad for these Stalinist storm troopers the video shows a different picture. What it looks like, is the cop on the right fires a warning shot into the air. Finicum naturally turns in that direction, due to the noise, and his right hand naturally approaches his weapon. This gives the henchmen on the left cause to shoot him in the face. This appears to be entirely planned out.
