By ED WHITEA law enforcement agency executing the Trump administration’s immigration crackdown has been described as a serial violator of court orders in Minnesota. It was a federal judge with a conservative pedigree who has added a powerful voice to a saga that has stirred the nation. “ICE is not a law unto itself,” Chief U.S. District Judge Patrick Schiltz wrote this week, referring to U.S. Immigration and Customs Enforcement. In November, a Chicago federal judge put similar limits on the use of force and said a Border Patrol commander lied about threats faced by officers. The Department of Homeland Security responded by calling him an “activist judge.” Schiltz canceled the hearing after an immigrant in that case was released.
