Samuel DuBose, an unarmed black man in Ohio, was pulled over by University of Cincinnati police officer Ray Tensing for a missing front license plate on his car. He was then shot and killed by the officer, who is now charged with murder. Tensing was arraigned today and pleaded not guilty. His bail was set at $1 million. The incident has drawn attention to the city, which has been hailed as a model for police reform after riots 14 years ago led to department-wide changes.
