The response to the killing of UnitedHealthCare CEO Brian Thompson says a lot about our society. We've seen his death mocked online and his accused assassin, who is now facing a terrorism charge, outright supported and even admired, while Thompson's family grieves.Justifying violence is not OK. In recent years people have been far too willing to justify violence to support their views.From the violence and destruction of businesses during riots after George Floyd's killing, to the clashes with police and even multiple fatalities during the insurrection at the Capitol – and now an execution in broad daylight on a New York City sidewalk. It even spurred a new hit list and torrent of threats for other CEOs at the crosshairs of social issues. Where does this mob justice end? It is true that many people have had heartbreaking experiences with the health care system in this country. The issues are valid. The violence is not. There is an argument to be made that throughout history great change has sometimes followed tragedy and even violence. But history also teaches us change can come about through nonviolence and activism—the kind of righteous engagement that brings people together. It's so much better to build rather than destroy, to love instead of hate, to get involved and find common ground for solutions instead of withdrawing and only coming together to hurt each other. We don't have to make violence the catalyst for change – we can choose another path.Ariel Roblin is the president and general manager of KCRA 3 and My58. See more of her editorials here.
