The American Civil Liberties Union (ACLU), has published a guide to photographers' rights in the US. Following a series of cases of photographers being challenged, and even charged, over shooting images and video of police officers, the ACLU has published a guide to what you are allowed to do as a photographer. It goes on to advise on how to respond if you are challenged by the police and details the additional considerations for people capturing sound recordings of events.
