This still image taken from video by Diamond Reynolds shows a police officer pointing a gun at her boyfriend, Philando Castile, during a traffic stop on Wednesday, July 6, 2016 in Falcon Heights, Minn. The officer shot Castile, and Reynolds apparently livestreamed the aftermath on Facebook from the passenger seat. As the video and word of the shooting spread, scores of people gathered at the scene and outside the hospital where Castile died. (Diamond Reynolds via AP)
