Is racism on rise in America?

America being a super power often puts pressure on other countries to establish the rule of law or democracy. They are vocal about violation of human rights all over the world. But paradoxically, they themselves do not care for those things. The killing of Eric Garner (by using chokehold) is nothing but a racial killing, as the protesters have termed it, because the grand jury did not indict the police officer involved in his death. American police is continuously killing and harassing black people there. Michael Brown is another victim of police brutality. There are many more examples of police killing. It seems racism in America is rising or can we say that it has been there all along?
