Ahead of the latest raids, immigrant advocates had attempted their own detective work, trying to ferret out where and how the arrests would be conducted. In Atlanta, lawyers began posting on social media based on a report that ICE agents had rented 40 minivans for the week, a rumor that quickly spread but remained unconfirmed.
Those arrested were expected to be held in detention centers in Texas and Pennsylvania that are specially equipped to hold families. But because of space limitations, some would probably be booked into hotel rooms until their travel documents could be prepared, ICE officials said. The agency’s goal is to deport the families as quickly as possible.
There were a large number of deportations during the Obama administration, but they mainly involved single adults who had been convicted of crimes.
“During Obama, the overwhelming majority of enforcement actions targeted criminal aliens,” said John Cohen, former acting under secretary at the Department of Homeland Security during the Obama administration. “This operation apparently specifically targets families who for the most part present no risk.”
While ICE agents must wait for their targets to come outside of their homes voluntarily in order to arrest them, they are expected to come prepared with common tactics they have used in the past to coax their targets into cooperating. For example, agents often carry decoy photos, holding them up to the windows of migrants who are being targeted and pretending to be looking for someone else, to persuade them to open the door.
Agents also sometimes claim to be police officers responding to calls about domestic disturbances or gas leaks. They also have used social media to capture targets by making fake accounts on online dating websites and arranging rendezvous.
Mr. Cohen said the raids were impractical and not likely to improve the situation at the border — where holding facilities have been overrun recently, and as a result, migrants have been living in substandard conditions.
