The police sat on their horses off to the side of Lafayette Park. They stayed out of the demonstation itself. Evidently, they didn't consider the protest likely to get out of hand. Usually, the protests can't get a permit for Lafayette Park, which is barricaded off. They only had a waist high fence down the middle of Pennsylvania Avenue to keep the crowds away from the White House. The cops look bored, unaware that they were the forces of oppression in a fascist Amerikkka that was oppressing everyone, all the time, everywhere.
