Footage shows the moments before 37-year-old Alex Pretti was shot and killed by US immigration agents in Minneapolis during an enforcement operation on January 24. While the Department of Homeland Security maintains a Border Patrol agent fired in self-defense after Pretti allegedly resisted and approached with a gun, bystander video shows him holding only a phone and trying to help others before being pepper-sprayed, pinned down, and fatally shot, sparking widespread protests and criticism of federal authorities.
