(CNN) -- [Updated 2:30 p.m. Monday, November 21] An Occupy Wall Street protester raises his fist Thursday while chanting on the Brooklyn Bridge in New York City.
Photographer Andrew Burton said Thursday was one of the most violent days yet in the movement.
"I was on top of people, and people were on top of me," said Burton, who works for Getty Images. "I had a police officer body-slam me for trying to take a photo of a protester being arrested on the pavement."
More of Burton's great imagery can be found on CNN's new photos blog.
"I photographed protesters aggressively resisting arrest, but also ... protesters dancing in the streets, hugging during a quiet moment and offering the police a candle as a sign of peace," Burton told CNN's Angie Walton.
