A federal judge on Thursday dismissed the indictment against two people accused last month of "ambushing" federal agents conducting an immigration sweep in Chicago.

For nearly two months, federal agents have been carrying out surprise raids in Chicago in pursuit of the Trump administration’s immigration agenda, emerging from unmarked vehicles in neighborhoods throughout the city to confront and detain stunned members of the public.

Local officials and community leaders had urged residents to stay safe as they braced for increased immigration enforcement actions.

The dayslong immigration crackdown that arrived in Charlotte, North Carolina, last week appeared to end with the same level of confusion it began with, as local officials announced the operation concluded Thursday while federal officials refuted those claims.

A federal appeals court temporarily halted an order restricting immigration agents' use of force in the Chicago area, calling the ruling "too prescriptive."

Skip Yates was in his home office when he heard screams and the shrill whistles Chicagoans have been blowing to signal immigration agents are nearby. He peered from his veranda to see large vehicles and tear gas wafting down the street. Yates shut the door as he began coughing, his eyes burning.

A review of polls of the general public shows how opinions on immigration vary widely based on the details included in poll questions.
