In this Tuesday, Feb. 7, 2017, photo released by U.S. Immigration and Customs Enforcement shows foreign nationals being arrested this week during a targeted enforcement operation conducted by U.S. Immigration and Customs Enforcement aimed at immigration fugitives, re-entrants and at-large criminal aliens in Los Angeles. Immigrant advocates on Friday, Feb. 10, 2017, decried a series of arrests that federal deportation agents said aimed to round up criminals in Southern California but they believe mark a shift in enforcement under the Trump administration.
