Arya News - Most Americans believe health insurance profits and coverage denials share responsibility for the killing of UnitedHealthcare`s CEO — although not as much as the person who pulled the trigger, according to a new poll. In the survey from NORC at the University of Chicago, about 8 in 10 U.S. adults said the person who committed the killing has “a great deal” or “a moderate amount” of responsibility for the Dec. 4 shooting of Brian Thompson. Despite that, some have cast Luigi Mangione, the 26-year-old suspect charged with Thompson’s murder, as a heroic figure in the aftermath of his arrest, which gave rise to an outpouring of grievances about insurance companies.
