GRAZ, Austria — In my degree thesis I tried to present El Paso as a political nation-state buffer zone between Mexico and the United States, an unconventional view of the Sun City sparked by the near-omnipresence of the Border Patrol. Everything started with naïve questions to my Mexican-American roommate regarding the Border Patrol. I would sometimes see them eat tacos at the table next to mine – in the first couple of weeks after my arrival in El Paso in August 2007. What were they doing? What were they after?
