Assuming that the story is true, what I don't really get is police using all the f* words and saying things like "don't come in America then" or "go back to your country". I would feel offended by that. "I'm still eating my sandwich while watching the scene. The mighty authority doesn't seem to like it, grab my sandwich and throw it on the ground." - first thing that came to my mind after reading this was "Threw It On The Ground" song by lonely island. That must've been a pretty evil sandwich ;)
