 Some scholars also see nothing inherently contradictory in the notion of “violent civil disobedience” independent of its communicative aims. John Morreall views a person’s physical assault on a slave owner chasing a runaway slave, in violation of the Fugitive Slave Act of 1850, as a case of “justifiable violent civil disobedience” (1976, 42–3). Jennifer Welchman considers “violence, threats of violence, covert acts of sabotage, blackmail, and even assault” as means that civil disobedients can justifiably use to obstruct and frustrate injustice (2001, 105). But, arguably this route is too hasty, as it disregards what seems to be an essential and powerful association between civil disobedience and non-violence: the civility of civil disobedience seems to entail non-violence. The difficulty is to specify the appropriate notions of violence and non-violence.
