Federal immigration agents fatally shot 37-year-old Alex Pretti in Minneapolis during an enforcement operation, touching off large, sometimes confrontational protests and renewed debate over federal enforcement in U.S. cities. Authorities say Pretti approached officers with a 9mm handgun and agents fired “defensive shots,” while family members, witnesses and bystander footage dispute that account — some footage appears to show Pretti holding a phone. The death follows an earlier Jan. 7 fatality involving immigration authorities in the city and has produced sharp partisan and local-state-federal clashes. Minnesota’s governor mobilized the National Guard and said the state would lead the investigation; local leaders and activists demanded federal officers withdraw. Conflicting official statements, restricted access for independent investigators and the release of agency footage have deepened tensions. The case has prompted litigation, calls for independent probes, and nationwide demonstrations that have kept pressure on DHS funding and enforcement policies.
