This chapter identifies the consequence of perceived foreignness on the prosecution of political violence cases in the United States. Methodologically, descriptive statistics reveal that Foreign Terrorist Organization affiliation elongates a defendant’s average sentence length, whereas foreign citizenship, on average, does not significantly alter a defendant’s average sentence length. The most essential presumption being made in this research is that foreign affiliation and the prosecution of political violence share a dependent relationship. If that relationship is deemed ineffective, the findings of this research are thus unsupported and insignificant. From preliminary data collection, group selection, and group comparison, theory is born. According to a grounded theory approach, theory must be developed to suit four properties: fitness, understanding, generality, and control. Grounded theory is, by definition, constructing the framework by which a concept is established based on a given set of data.
