“I was shocked to see so many white kids out here”

From Minneapolis to Washington, D.C., marchers noticed the change, and wondered what it meant that so many white Americans were showing up for the cause of justice for black Americans.

“I was shocked to see so many white kids out here,” said Walter Wiggins, 67, as he sat near the heart of the protests in Washington last week.

White protesters made up 61 percent of those surveyed in New York over the weekend, according to the researchers, and 65 percent of protesters in Washington. On Sunday in Los Angeles, 53 percent of protesters were white.
