 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 in 1981. The killer of Judge Roll and the wounder of Gabby Giffords and 16 other people in Tucson. The mugging, the brutal attack on Paul Pelosi in 2022. These are deranged individuals without political motives. But then we've got the killing of JFK.
