The fatal shooting of 37-year-old Alex Pretti by federal immigration officers in Minnesota has become a defining moment in the Trump administrations immigration crackdown, triggering protests and exposing deepening tension between federal authority, state power and public accountability in the US.
What began as an enforcement operation has evolved into a wider political and institutional test, drawing scrutiny from state governments, congress and civil-rights groups.
Pretti, an intensive-care nurse and US citizen, was shot during a federal immigration enforcement operation in Minneapolis in late January.
