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 say the person who committed the killing has "a great deal" or "a moderate amount" of responsibility for the Dec. 4 shooting of Brian Thompson. About 7 in 10 adults say that denials for healthcare coverage by insurance companies, or the profits made by health insurance companies, also bear at least "a moderate amount" of responsibility for Thompson's death. 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.
