He's being completely serious when he says his name is G-d. He knows he holds their lives in his hands. Notice how he flexes on the black guy while yelling, "what are you going to do to me?" into the phone. Then he lies and says they are trying to put a boat into the water. Finally he flips the narrative and yells, "you're harassing me, you're harassing me," as if some wolf pack just descened upon him. Take away Amy Cooper's Academy Award and give it to this guy, then lock his ass up.
