Moppin-Buckskin was not armed, but the officers believed he was reaching for his waistband when they opened fire, Wilken said in a15-page ruling Tuesday.

"The undisputed evidence shows that Officers Jimenez and Borello acted reasonably when they used deadly force against Mr. Moppin,"Wilken wrote. "The officers shot Mr. Moppin only after he failed to come toward them, as ordered, dropped his hands and then made a movement toward his waist area as though reaching for a weapon."
