Federal immigration agents forced open a door and detained a U.S. citizen in his Minnesota home at gunpoint without a warrant, then led him out onto the streets in his underwear in subfreezing conditions, according to his family and videos reviewed by The Associated Press. ChongLy "Scott" Thao told the AP that his daughter-in-law woke him up from a nap Sunday afternoon and said that U.S. Immigration and Customs Enforcement agents were banging at the door of his residence in St. Paul. He told her not to open it. Masked agents then forced their way in and pointed guns at the family, yelling at them, Thao recalled.
