台灣的民主在解嚴後，邁向嶄新的里程，憲法中人民的集會遊行權利，亦受到更明確的法治規範和保障。從近期大陸海協會副會長陳雲林先生來台所引發的抗爭，以及 2006年間紅衫軍發動有史以來最大型的群眾抗爭來看，在在顯示了媒體在大型群眾抗爭中，不僅扮演著傳遞政府與民眾資訊的關鍵角色，也在執法機關的危機處理中舉足輕重，甚至，執法機關如能善用媒體影響，可以達到冷卻群眾激情、降低動員能量的效果，亦有利於澄清不實指控，強化公權力形象，這是以前執法機關在處理群眾運動時，從未曾思考過的領域。 本文從聚眾活動及危機處理的面向，回顧 2006年間紅杉軍運動期間，警方的執法作為與媒體因應策略，並輔以民調的實證分析，期將結論作為未來面臨類似事件的輿情處理範例，並改善民眾對執法機關的認知與評價。
