They killed a person because the individual could not hear, now imagine if you are a tourists that does not know the language well, the cops ask you to raise your hands but you think they want your IDs, you put your hand in the pocket and you will get killed. It seems to me that is better not to go as a tourist in US if you are not good enough in english, if you have the wrong illness or skin color.
