Driver ran a stop light, almost crashed into us, was indignant afterwards and sped around us on double yellow lines to speed over 40mph in a 25. Once we photographed the back of his license plate, he then turned into our lane and followed me back to the apartment until i threatened to shoot him in self-defense, at which point he sped off and the police were called.
