Violence erupted at the University of California, Los Angeles after pro-Israeli counter-demonstrators attacked a pro-Palestinian campus encampment. Bubbling tensions on the campus boiled over following the alleged breach of a “buffer zone” between the rival groups.
I think this is a good example of how vigilantes often work to support the state’s goals when it can’t legally/easily complete their goals.
For every fascistic government still bound by laws, there will be fascists willing to ignore them to support it. See this. See the KKK carrying out lynchings on people who are barely escaping the grasp of the state. See the settlers illegally settling on Palestinian land to carry out the state’s goals of ethnic cleansing.
