Radical animal rights and environmental activism is considered domestic terrorism under the Animal Enterprise Terrorism Act. Traditional models of terrorism purport that there is a path to radicalization that is influenced by an individual's sense of identity and ideological beliefs. Using collective identity theory and cognitive experiential self-theory as the framework, the purpose of this quantitative study was to examine whether social identity, cognitive processing mode, and ideological beliefs were predictors for engagement in radical animal rights and environmental activism. The Three Factor Model of Social Identity Scale, the Rational Experiential Inventory, and the Activism Orientation Scale were used to collect data from a sample of 65 self-described radical animal rights and environmental activists. Standard multiple regression analyses were used to test each hypothesis. According to the results of the study, only rational processing mode, F(6, 64) = 3.18, (p < .05 ), was a predictor of likeliness to engage in radical animals rights and environmental activism. Although ideology was not a significant predictor, exploratory analysis showed that ecofeminism demonstrated predictive value, F(2, 64) = 6.12, (p < .05). This study contributes to positive social change by expanding the understanding of the profile of radical activists, which may aid those who support radical actions and those who oppose such actions in opening a meaningful dialogue whereby solutions to issues facing the environment and animals can be addressed with successful outcomes.

From 1990-2010 ecoterrorist attacks by the Animal Liberation Front (ALF) and Earth Liberation Front (ELF) created an anomaly in the U.S. with millions of dollars in property destruction. Interestingly, in a post 9/11 era, the FBI warns that the number one threat to U.S. national security is not religious terrorism, but rather environmental-group terrorism. When examining this topic further, there is a void in analysis between examining ecoterrorist attacks and U.S. public policy. Is there a statistical significant relationship between terrorist attacks by ALF/ELF and U.S. public policy towards terrorism? Is per capita income an influence on the attacks occurring in specific states? This study seeks to analyze such relationships through an exploratory analysis and case study approach. I conducted a trend analysis on attacks by ELF/ALF from 1990-2010 and the subsequent adoption of U.S. public policy towards terrorism. I analyzed per-capita income by region and its relationships to attacks occurring. I performed chi^2 hypothesis testing in order to determine the statistical significant relationships between ELF/ALF attacks/U.S. public policy and per capita income by State. The findings of this study suggest that the definition of terrorism is ambiguous and can lead to alternative interpretations, which can affect U.S. public policy towards terrorism. Attacks by ALF/ELF are not deterred by U.S. public policy. Also, a majority of attacks by ALF/ELF are most likely to occur in states that rank in the top 20th percentile regarding per capita income and occur mainly on the west coast. The statistical significance of the relationships between ELF/ALF attacks and U.S. public policy demonstrate that these two entities are mutually exclusive. Per capita income levels by states and ELF/ALF attacks are also mutually exclusive. This study creates an improved understanding of what constitutes terrorism and an understanding of the radical elements in the environmental movement and its place in a post 9/11 America. The significance of this study is to provide a model for analysis of terrorist attacks and government responses and provide a framework of inquiry for the fields of terrorism,public policy and conflict studies.
