In North Dakota, a group of lawyers from the National Lawyers Guild has filed a class action lawsuit against Morton County Sheriff Kyle Kirchmeier, Morton County and other law enforcement agencies, arguing they are using excessive force against Native American water protectors fighting the $3.8 billion Dakota Access pipeline. In recent weeks, police have attacked the protectors with rubber bullets, bean bag rounds, water cannons in subfreezing temperatures, sound cannons, explosive tear gas grenades and concussion grenades, injuring hundreds of people. One water protector, Sophia Wilansky, was critically injured during one police attack, after her father says a police concussion grenade exploded and nearly blew her arm off.
