After protests started following Michael Brown's shooting in Ferguson, Mo., by a police officer, police told protestors they had to keep walking and they couldn't keep still. Now U.S. District Judge Catherine Perry has issued a preliminary injunction to stop police from enforcing a practice she found to be unconstitutional, CNN reports: "In some cases, officers told protesters they couldn't stand still for more than five seconds. In others, the protesters were told they were walking too slowly."
