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. So says a new poll from NORC at the University of Chicago. It finds that about 8 in 10 Americans say that the person who committed the killing has “a great deal” or “a moderate amount” of responsibility for the Dec. 4 shooting of Brian Thompson. Still, some see suspect Luigi Mangione as a heroic figure. About 7 in 10 adults say coverage denials or health insurance profits also bear at least “a moderate amount” of responsibility for Thompson’s death.
