MINNEAPOLIS — On the seventh Friday of the largest immigration enforcement operation in a U.S. city, during a presidency defined by the issue, a growing cadre of activists searched tinted car windows for masked federal agents. A man facing a deportation order in connection with a rape more than 20 years ago begged one of those agents for a final moment to say goodbye to the mother of his children. A child care worker blowing desperately on a whistle sprinted after two federal officers pursuing a person. And a 22-year-old Ecuadorian asylum seeker ventured out nervously to a new job in a city that seemed to be tilting on end, in a country threatening to shake her loose.
