Public relations research has paid considerable attention to foreign terrorist crises but relatively little attention to domestic ones—despite the growing salience of domestic terrorism in the United States. This study content analyzes 30 years of network television news coverage of domestic terrorism to gain insight into four theoretical issues of enduring interest within the literature on news framing and crisis management: sourcing, contextualization, ideological labeling, and definitional uncertainty. Results indicate that the sources called upon to contextualize domestic terrorism have shifted over time, that ideological labels are more often applied on the right than the left, and that definitional uncertainty has increased markedly in recent years. Implications for the theory and practice of public relations and crisis management are discussed.

公共关系研究对外国恐怖主义危机给予了极大的关注，但对国内恐怖主义危机的关注却相对较少，尽管美国国内恐怖主义的严重性日益增加。这项研究内容分析了30年网络电视新闻对家庭恐怖主义的报道，以洞悉新闻框架和危机管理方面的四个长期引起关注的理论问题：寻源，语境化，意识形态标签和定义不确定性。结果表明，要求将国内恐怖主义情境化的来源已经随着时间推移而发生了变化，意识形态标签在右侧的使用比左侧更多，并且定义的不确定性近年来显着增加。
