The Los Angeles District Attorney's Office says a grand jury indictment was unsealed charging a former Los Angeles police officer in the 2015 shooting death of an unarmed homeless man. Clifford Proctor pleaded not guilty to second-degree murder on Friday. Brendan Glenn was killed during a struggle with officers outside a bar. His name became a rallying cry against police shootings in Los Angeles. The indictment comes after the previous district attorney reexamined four use-of-force cases involving police. Current District Attorney Nathan Hochman will decide whether to continue with the case. A previous district attorney in 2018 had declined to charge Proctor.
