A surge in federal immigration enforcement in Chicago has led to increased tension and public outcry. Officers deployed tear gas to disperse crowds during protests following various immigration raids, notably coinciding with a Halloween parade in Old Irving Park. Reports indicate that federal agents have utilized tear gas multiple times this week alone, leading to several arrests and confrontations with community members who interrupted these operations. High school students were reportedly detained during one protest, and residents expressed feelings of humiliation and fear in the wake of ICE raids across neighborhoods, including wealthier areas. Activists and citizens have organized rallies in response, emphasizing the need for change and raising concerns about the tactics employed by federal agents, which have been described as excessive and alarming. The escalated enforcement has not only resulted in confrontations at immigration sites but has prompted schools to implement lockdowns as safety measures amid ongoing ICE activity in the city.
