The Arlington, Texas, police recruit who fatally shot an unarmed college football player during a break-in at a car dealership early Friday has been fired for exercising poor judgment, the police chief said Tuesday. Christian Taylor, 19, was fatally shot by Arlington Police Officer Brad Miller, 49, after police were called to a break-in report at the Classic Buick GMC dealership at around 1:06 a.m. Miller, a recruit officer who was undergoing supervised field training, entered the building alone and without telling other officers, setting into motion a chain of events that led to the deadly shooting.
