The American Civil Liberties Union requested a reinstatement of constraints on federal officers’ tactics against protesters in Minnesota after federal officers in Minneapolis fatally shot a 37-year-old man.

U.S. District Judge Katherine Menendez agreed to impose constraints earlier this month, but the move was temporarily lifted by the U.S. Court of Appeals for the 8th Circuit on Wednesday. The ACLU is now arguing that the situation has escalated to an extent that the restraints are more urgently needed.
