In New York City, demonstrators started at Union Square at around nightfall, and then marched north to Times Square, meandering between lanes of traffic as police followed. The protesters, who seemed to grow in number as the night wore on, disrupted traffic on the FDR Drive and congregated at the entrances to the Williamsburg and Manhattan bridges and the Queens Midtown Tunnel.
Commissioner William Bratton said police were giving protesters "breathing room."
"As long as they remain nonviolent, and as long as they don't engage in issues that cause fear or create vandalism, we will work with them to allow them to demonstrate," he said.

In Cleveland, several hundred people marched down a freeway ramp to block rush-hour traffic, protesting not only the decision in Ferguson but also the fatal shooting Saturday by an officer of 12-year-old Tamir Rice of Cleveland, who had a pellet gun that looked like a real firearm.
"The system wasn't made to protect us," said one of the protesters, 17-year-old Naesha Pierce. "To get justice, the people themselves have to be justice."
