On March 12th, Immigration and Customs Enforcement issued a press release about an "enhanced" operation that the agency had conducted the previous week in New Mexico. Forty-eight people were arrested in Santa Fe, Albuquerque, and Roswell. Twenty of them had been "arrested or convicted of serious criminal offenses," which included homicide, sexual assault, drug trafficking, and shoplifting. Others had committed "immigration violations such as illegal entry and illegal re-entry," and twenty-one had final orders of removal issued by an immigration judge. On March 16th, the New Mexico chapter of the American Civil Liberties Union filed a complaint with two oversight agencies within the Department of Homeland Security: the Office for Civil Rights and Civil Liberties and the Office of the Immigration Detention Ombudsman. "ICE has not identified any of the 48 individuals," the letter said. "ICE has not indicated where any of them are being detained, whether they have access to counsel, in what conditions they are being held, or even which agency is holding them." In the past two and a half months, ICE has ended a long-standing policy discouraging arrests at schools, places of worship, and hospitals; its officers have also allegedly entered residences without warrants, arrested U.S. citizens by mistake, and refused to identify themselves while whisking people away on the streets of American cities.
