80s Movie Sub-Plot Question

I am looking to remember the title of a movie that I saw in the 80s. The sub-plot was of a young girl who was a photographer or photo journalist who was sent to take photos of two african american boys who were on trial for some sort of crime. The scene I recall is the girl taking photos of them (possibly outside a courthouse) and she gets knocked down out of the way by the crowd but manages to get off a few photos. She is then shown in a darkroom developing the photos and from what I recall somehow the photos she took exonerates the two boys. Sound familiar to anyone??
