 Lauren McGaughy, NPR News. A video of a California driver slapping an autistic boy who touched his car at a red light is going viral. The incident took place on July 1st in the Pacoima neighborhood of Los Angeles. After the video became public, concerned residents helped the homeless family file a police report against the man who was driving a Mercedes-Benz sedan. I'm Duahli Saikao Tao, NPR News in New York.
