During the spring and summer of 1963, there were protests in over a hundred United States cities, including Northern cities. There were riots in Chicago after a white police officer shot a 14-year-old black boy who was running away from the scene of a robbery. In Philadelphia and Harlem, black activists and white workers fought when the activists tried to integrate state-run construction projects. On June 6, over a thousand white people attacked a sit-in in North Carolina; black activists fought back, and a white man was killed.
