The Scope of Political Conflict and the Effectiveness of Constraints in Contemporary Urban Protest.

This paper examines the effectiveness of the use of constraints (e.g., direct action tactics and violence) by protest groups. It is suggested that the development of theoretical understanding of protest movements requires that scholars turn their attention away from the question, "How effective is the use of constraints by protesters?" and instead address the more refined question, "Under what conditions is the use of constraints by protesters both most effective and least effective?" In pursuit of answers to this latter question, hypotheses are developed suggesting that the effectiveness of constraint utilization depends on the degree and direction of public (third party) involvement in the protest incident. An examination of 212 protests targeted at elected officials and public administrators in American cities during the period between 1960 and 1971 provides support for the following propositions. Constraint utilization will be most effective when third parties are either uninvolved in the protest or when they are involved and unsupportive of protester demands. Under these conditions, constraints may be effective resources enabling protesters to coerce targets into being responsive to their demands. Constraint utilization will be least effective when third parties are involved and supportive of protester demands or are attentive but initially neutral or divided in their support of the protesters. Under these conditions, the use of constraints may alienate those third parties who might otherwise be influential allies of the protesters. [ABSTRACT FROM AUTHOR]
