Two separate videos uploaded to YouTube on Wednesday show the officer pointing a rifle at protestors.
"Gun raised, gun raised and pointed," a protestor shouts out, alerting others as the officer approaches closer.
"My hands are up," another protestor says.
"I will fucking kill you, get back!" the officer shouts.
Another protestor asks for the officer to identify himself.
"What's your name, sir?" he asks.
"Go fuck yourself," the officer replies.
In another video, protestors can be heard shouting at the officer to lower his weapon. At least one other cop can be seen trying to deescalate the situation by placing his hand on the weapon to lower it.
