sounded like "don't shoot" to me
listening again, maybe it was "hands up - don't shoot"
A dude with a rifle was followed by a dude holding a handgun behind his back in one of the series of vids on undercover vic's twatter, suggestion was it was that handgun dude who was kicked, then shot the two guys, one in the arm. I'm thinking he was antifa following the rifle boy but was mistaken for militia, shot his own comrades, then leaving the scene the headshot guy got in the way. rifle boy just ran over to see what happened.
