It reads to be that you’re being purposely obtuse. Any security is going to take into account the appearance of a person. Undoubtedly you understand what that means in practice in America—-that appearance has been boiled down to just race: “be on the lookout for a black man.” It’s lazy and should be called out so that police are forced to do work and learn the difference between a non-violent angry person and a violent angry person in a crowd.
