A US federal judge has restricted Immigration and Customs Enforcement (ICE) agents from using tough crowd control methods on peaceful protesters in Minneapolis. Judge Katherine Menendez ruled Friday night that federal agents cannot arrest or pepper spray demonstrators peacefully watching ICE actions. The move comes before weekend protests planned against wide immigration raids in the city. It follows the January 7 shooting of Renee Good by an ICE agent, which has sparked unrest. The Department of Homeland Security said it is protecting officers from violent rioters. Minnesota officials urged protesters to stay peaceful. The National Guard has been placed on alert and extra police deployed before protests and a conservative counter-march. Judge Menendez’s detailed 83-page order stops federal agents from arresting or using pepper spray on peaceful protesters. It also stops agents from stopping or detaining vehicle drivers without good reason. "The act of safely following [immigration agents] at an appropriate distance does not, by itself, create reasonable suspicion to justify a vehicle stop," the order states. DHS told CBS it acts within the law to protect officers and the public from dangerous rioters. The White House criticized the ruling. “This absurd ruling embraces a dishonest, left-wing narrative," spokeswoman Abigail Jackson said. "Federal agents have acted lawfully to protect themselves and their operations from interference." Since Good’s shooting, Minneapolis has seen protests and some clashes with federal officers. The Justice Department also announced an investigation of Minnesota Governor Tim Walz and Minneapolis Mayor Jacob Frey. They are being probed for allegedly trying to block federal immigration work. US Attorney General Pam Bondi warned, "No one is above the law." Walz and Frey called the probe an "authoritarian" use of the justice system against opponents.
