 I've got three large categories of political violence beginning with the Kennedy assassination in 1963. I want to try them out on you for your immediate reaction. Category one is mob violence of the sort we saw on January 6th, the aftermath of George Floyd's murder all across the United States, the 1968 riots, the 1971 riots. We've got mob violence. Then we've got deranged individuals such as John Hinckley who attempted to kill the president for motives unrelated to politics.
