The Tucson city council voted unanimously in late January to begin a process that would restrict Immigration and Customs Enforcement (ICE) agents and Department of Homeland Security officials from using city property for enforcement activities without a judge-signed warrant.

The decision came two weeks after Renee Good, a mother of three, was fatally shot by an immigration agent on the streets of Minneapolis in January. The shooting prompted swift action from Tucson lawmakers located 1,300 miles from the incident site.

The new restrictions would block federal immigration enforcement agencies from staging operations on Tucson city property unless they obtain proper judicial warrants. The measure represents the city's effort to limit federal immigration enforcement activities within its jurisdiction.

The policy change has set up a potential conflict with state Republican officials, who are expected to challenge Tucson's actions. City officials acknowledge they are preparing for pushback from the state level over their decision to restrict federal immigration operations.

The Minneapolis shooting that triggered Tucson's response has also affected immigration court personnel. David Koelsch, a former immigration judge based in Maryland, traveled to the scene of the shooting to observe. According to reports, some immigration judges have left their positions through terminations or buyouts amid the current political climate.
