Unrest and rioting in cities in throughout the United States, the world’s largest economy and one of its richest, have been going on now for a week. Protests have taken place in at least 75 cities and have reached the gates of the White House. The immediate cause for these riots was the killing of an African American man by a white police officer in an especially brutal way by keeping a knee on his neck. This killing was filmed as it was happening in public on the roadside and showed other police officers looking on while people passing by plead with the police to get off the dying man.
