Protesters are still demanding justice for the shooting death of unarmed teen Michael Brown by a police officer in Ferguson, Missouri.
Rallies were held in more than three dozen cities, including Pittsburgh, Thursday night.
About a dozen people held signs and candles on the steps of the city-county building downtown.
“If we don't come out and say something and stand against this, we will all lose our rights,” said Carolyn Cane.
“We need more peace in the world and more people who care,” said Jeff Kromer.
