“This street dead-ends in a fishbowl of concrete: a line of shops to the right, some formidable, blockish government buildings to the left, and a wall directly in front, which is topped with a second wall, which is topped with a third wall, which is topped with razor wire and mounted cameras. It’s behind this wall, stretching high up into the sky, that the American flag moves stiffly in the mild wind. Only a few feet away from it, on this side of the fence, a Mexican flag also flies.”
