Off campus, if you deliberately break a window, and the cops see you doing it, you get arrested. (Whether the local Soros-supported district attorney will press charges is another question.) If you assault someone, you will get arrested. If you threaten someone with imminent bodily harm, and the police hear it and believe there is a chance you will act upon that threat, you will get arrested.

If you take over a building, bring heavy chains to lock up the doors so that the authorities cannot enter, take a facilities worker hostage, and refuse to leave until your demands are met, you are not just a criminal; you are only a bit behind Hans Gruber.
