The criminal trial has begun for the New York City police officer accused in the November 2014 killing of unarmed African American Akai Gurley. Gurley was in the dimly lit stairwell of a Brooklyn housing project when Officer Peter Liang opened fire. Liang faces charges of manslaughter, criminally negligent homicide, assault and official misconduct. Defense attorneys say the shooting was accidental. At Monday’s opening hearing, prosecutors said Liang was more concerned with protecting his job than he was with saving Gurley’s life as he lay dying. Liang reportedly did not call for help or respond to police radio contact for several minutes after opening fire.
