New York: Thousands of protesters marched in New York City for the second night Tuesday, chanting loudly and blocking traffic on some of Manhattan's busiest streets to express outrage over the decision not to indict a white police officer in Ferguson, Missouri, in the death of an unarmed black man. The police said that some protesters had been arrested, although no figures were immediately available. A demonstrator burns an American flag during a protest in New York City.
