Boston prosecutors released video Friday of the March 27 shooting of a police officer and the subsequent killing of the gunman.
The officer wounded, John Moynihan, is white. Angelo West, the gunman shot to death by officers, was black.
After the shooting, community leaders in the predominantly African-American neighborhood of Roxbury, where the shooting occurred, were quick to call for calm. One said the officers were forced to return fire, CNN reports.
Saturday, Officer Moynihan, who was decorated for his actions immediately after the Boston Marathon Bombings, was released from the hospital.
ABC news reports the Boston Police Department described Officer John Moynihan's condition as "serious but improving." He has been hospitalized since March 27 when he was shot just below his eye during a traffic stop.
