A newly introduced bill that would bar former Immigration and Customs Enforcement agents from working in state and local law enforcement in Illinois is sparking intense debate, with supporters calling it a necessary accountability measure and critics warning it could worsen police shortages and undermine public safety. State Sen. Laura Fine, D-Glenview, who is also running for Congress, announced the legislation in a social media video this week, saying it was prompted by recent immigration enforcement actions she described as violent and intimidating.
