Carolina Panthers safety Eric Reid continued his anti-police protest by kneeling during the national anthem at the Panthers-Baltimore Ravens game in Charlotte Sunday, and just outside the stadium, about 30 people joined him.

The group carried signs with the names of people killed by police in Charlotte and around the country, Seeking Justice Consortium founder and organizer Kass Ottley told the Charlotte Observer. As the anthem began, they knelt in the intersection of Mint and Graham streets.

“We’re not kneeling to be unpatriotic,” Ottley said. “We’re kneeling to just really put a spotlight on the oppression of people of color in this country, and the history of oppression of people of color in this country.”
