A police officer from Montgomery, Alabama has been arrested on murder charges over the fatal shooting of an unarmed black man. His lawyer claimed the arrest was politically motivated, while the family says the man was shot because of his skin color. Officer Aaron Smith, 23, was arrested on Wednesday on suspicion of murder in the death of Gregory Gunn, a 58-year-old African-American man who was walking home around 3 a.m. a week ago when he was stopped. According to the Associated Press, police said Smith, who is white, believed Gunn looked “suspicious,” and left his police vehicle to approach Gunn on foot. It’s unclear exactly what happened during the confrontation between the two, but Gunn family attorney Tyrone Means told AP that Gunn was shot five times – three times in the chest and two times in the buttocks.
