Calls for changes to California’s police use-of-force policies echoed throughout the state capital Saturday after the district attorney announced that two local officers who fatally shot a black man after mistaking his cellphone for a gun will not face criminal charges.

Sacramento County Dist. Atty. Anne Marie Schubert said Officers Terrence Mercadal and Jared Robinet acted legally when they fired 20 rounds at Stephon Clark, 22, last March after chasing him into his grandmother’s backyard and confusing his iPhone for a weapon. Schubert said the officers acted reasonably because they saw a flash of light near Clark’s hand seconds before Clark advanced toward the officers.
