The deaths of Alton Sterling in Baton Rouge, Louisiana, and Philando Castile in Falcon Heights, Minnesota, were both captured on video. So were the deaths of Walter Scott, Eric Garner, and so many others. That’s not new. But technology has become more and more sophisticated, and so have the bystanders using it, primed by grim history to turn the camera on, and, increasingly, involve an audience. We explore the role of Facebook Live in the events of the last week and offer you our Breaking News Consumer’s Handbook: Bearing Witness Edition, for guidance on how to film the police, wisely and within your rights.

Brooke speaks with journalist Carlos Miller of Photography is Not A Crime, former police officer and current law professor Seth Stoughton, and Jennifer Carnig, former communications director for the New York Civil Liberties Union.
