PARK CITY   –  Hollywood stars used red carpet appearances at the Sundance Film Festival on Saturday to denounce the killing of an American protester who was shot dead on the streets of Minneapolis by federal immigration agents. Actress Olivia Wilde, who was in Park City, Utah, for the premiere of “The Invite,” said the death of a second protester in just three weeks at the hands of federal agents was “unfathomable.” “I can’t believe that we’re watching people get murdered in the street,” she told mediamen.“These brave Americans who have stepped out to protest the injustice of these ICE ‘officers,’ and watching them be murdered — it’s unfathomable. We cannot normalize it.” Wilde’s comments come after the killing of 37-year-old ICU nurse Alex Pretti, who died after being pinned to the ground and shot multiple times by federal agents. Pretti’s death came weeks after an Immigration and Customs Enforcement (ICE) officer shot and killed Renee Good, also 37, in her car in the city. Wilde, who wore an “ICE OUT” badge, said the US government violence against people exercising their right to free expression was “un-American.” “We may have a government that is somehow trying to make excuses for it and legitimize it, but we (Americans) don’t.” Fellow actress Natalie Portman, who was promoting “The Gallerist,” got emotional as she described her feelings over a “horrible day.”  “What is happening in our country is just obscene,” she told in Park City. “What (President Donald) Trump and (Homeland Security Secretary) Kristi Noem and ICE are doing to our citizens and to undocumented people is outrageous and needs to end.”
