WASHINGTON -- Police overseeing security at protests in Ferguson, Missouri, in August violated the constitutional rights of demonstrators and journalists by forcing them to stay in constant motion and not stop walking, a federal judge ruled on Monday.

Chief U.S. District Judge Catherine D. Perry held that the "practice of requiring peaceful demonstrators and others to walk, rather than stand still, violates the Constitution." She issued a preliminary injunction banning St. Louis County Police and Missouri State Highway Patrol officers from using the tactic.

"The evidence from plaintiff’s witnesses shows that the police, including those from St. Louis County, told many people who were either peacefully assembling or simply standing on their own that they would be arrested if they did not keep moving," wrote Perry, who sits on the U.S. District Court for the Eastern District of Missouri. "Some law enforcement officers told people that they could stand still for no more than five seconds. Others gave instructions that people were walking too slowly, or that they could not walk back and forth in a small area. http://www.huffingtonpost.com/2014/10/06/ferguson-protesters-keep-walking_n_5942482.html
