This essay will be a mix of case study and research paper.  This paper focuses on

– Border Security (ideally U.S.)

That’s the whole idea of this paper for this senior-level class, self-guided research in the study area of national security. Casual websites and Wikipedia may be used as supplements but are NOT acceptable as the only sources cited in your paper. Articles from reputable newspapers, scholarly articles, and law review articles are far better choices and will influence your grade accordingly.
