Using helicopters and chemical agents, immigration agents become increasingly aggressive in Chicago

Using helicopters and chemical agents, immigration agents become increasingly aggressive in Chicago 8 mins ago Activists, residents and elected leaders say increasingly combative tactics used by federal immigration agents are sparking violence and fueling neighborhood tensions in the nation’s third-largest city. That includes storming an apartment complex by helicopter as families slept and deploying chemical agents near a public school. About 1,000 immigrants have been arrested since an immigration crackdown started last month in the Chicago area. But U.S. citizens, immigrants with legal status and children have been among those taken into custody in increasingly brazen and aggressive encounters which pop up daily across neighborhoods in the city of 2.7 million and its many suburbs.
