If we make bad manners a crime, everyone will be a criminal.
In any event,bad manners do not excuse the criminal acts by the cops or make them legal.
Bad manners are not a crime, but people often commit crimes due to their bad attitude that is engendered by their chronic bad manners. Sorry, but this kid refused lawful requests to comply with campus rules which then led to his criminal acts of trespass and resisting arrest.
No doubt he thinks he's a crusader, but he's just another dumbass kid with a limited understanding of real tyranny.
