This article sketches a case for the importance of allowing and protecting civil disobedience in a democratic society. There are weighty reasons for non-enforcement of certain laws under certain circumstances, which undermines the legalistic claim that justice requires police to faithfully (try to) enforce all laws at all times. Furthermore, questions about how the police should respond to disobedient demonstrations are not settled by popular theoretical treatments of civil disobedience. Police responses to disobedient demonstrations should be guided by a principle (...) of proportionality. This proportionality requirement is more stringent in cases of self-generated needs for self-defense. Common police tactics like “skirmish lines” predictably escalate interactions and create a need for further defensive force, thereby violating the proportionality requirement. (shrink)
