Watch: How Alex Pretti shooting led Trump to shift course in Minneapolis

The death of Alex Pretti in Minneapolis, the second fatal shooting by federal agents there in less than a month, reignited a public outcry at the tactics used in the city's sweeping immigration operation.A growing backlash after the 37-year-old nurse was shot and killed on Saturday prompted a shift in tone from President Donald Trump - who said his administration was going to "de-escalate a little bit".But tensions have been high in Minneapolis for weeks, with frequent protests and confrontations between residents and federal agents. New footage published by the News Movement and shared with BBC News shows an altercation between Pretti and federal officers 11 days before his death.A spokesperson for the family has confirmed the man in the video is Pretti. In a separate statement released to media, the family's lawyer said "nothing that happened a full week before could possibly have justified Alex's killing".BBC analysis editor Ros Atkins examines this new footage - and explains how Trump changed course on Minneapolis.Produced by Katerina Karelli.
