An Immigration and Customs Enforcement (ICE), officer prepares an undocumented Salvadorian immigrant for a deportation flight bound for San Salvador, Dec. 8, 2010 in Mesa, Arizona. Of the 111 Salvadorians on the flight, most had criminal records and were sent home in chains. Although illegal immigration to the United States has decreased nationally in the last few years, ICE deported almost 400,000 people in the last 12 months, which is a record. Of that number, almost half had criminal records. The Obama administration has made targeting undocumented criminals a priority in its immigration enforcement policy.
